In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program including its Contributions under the new version.
Except as expressly stated in Sections 2 a and 2 b above, Recipient receives no rights or licenses to the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or otherwise. All rights in the Program not expressly granted under this Agreement are reserved.
No party to this Agreement will bring a legal action under this Agreement more than one year after the cause of action arose. Each party waives its rights to a jury trial in any resulting litigation. Applicable Licenses Unless otherwise indicated, all Content made available by the Eclipse Foundation is provided to you under the terms and conditions of the Eclipse Public License Version 2. Java and all Java-based trademarks are trademarks of Oracle Corporation in the United States, other countries, or both.
A Contribution "originates" from a Contributor if it was added to the Program by such Contributor itself or anyone acting on such Contributor's behalf. Contributions do not include changes or additions to the Program that are not Modified Works.
Modified Works shall not include works that contain only declarations, interfaces, types, classes, structures, or files of the Program solely in each case in order to link to, bind by name, or subclass the Program or Modified Works thereof.
For example, if a third party patent license is required to allow Recipient to Distribute the Program, it is Recipient's responsibility to acquire that license before distributing the Program. The Program including Contributions may always be Distributed subject to the version of the Agreement under which it was received.
In addition, after a new version of the Agreement is published, Contributor may elect to Distribute the Program including its Contributions under the new version.
Nothing in this Agreement is intended to be enforceable by any entity that is not a Contributor or Recipient. No third-party beneficiary rights are created under this Agreement.
If it is not possible or desirable to put the notice in a particular file, then You may include the notice in a location such as a LICENSE file in a relevant directory where a recipient would be likely to look for such a notice. You may add additional accurate notices of copyright ownership. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users.
You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price.
Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software and charge for them if you wish , that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code.
And you must show them these terms so they know their rights. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.
Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products.
If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary.
To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. Each licensee is addressed as "you".
To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy.
Propagation includes copying, distribution with or without modification , making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that 1 displays an appropriate copyright notice, and 2 tells the user that there is no warranty for the work except to the extent that warranties are provided , that licensees may convey the work under this License, and how to view a copy of this License.
If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other than the work as a whole, that a is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and b serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form.
A "Major Component", in this context, means a major essential component kernel, window system, and so on of the specific operating system if any on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and for an executable work run the object code and to modify the work, including scripts to control those activities.
However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same work. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met.
This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work.
This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright.
Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December , or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a The work must carry prominent notices stating that you modified it, and giving a relevant date.
This requirement modifies the requirement in section 4 to "keep intact all notices". This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a Convey the object code in, or embodied in, a physical product including a physical distribution medium , accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server operated by you or a third party that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source.
Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either 1 a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or 2 anything designed or sold for incorporation into a dwelling.
In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product.
A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term regardless of how the transaction is characterized , the Corresponding Source conveyed under this section must be accompanied by the Installation Information.
But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product for example, the work has been installed in ROM. The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed.
Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented and with an implementation available to the public in source code form , and must require no special password or key for unpacking, reading or copying.
Additional Terms. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it.
Additional permissions may be written to require their own removal in certain cases when you modify the work. You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. All other non-permissive additional terms are considered "further restrictions" within the meaning of section If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term.
If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. You may not propagate or modify a covered work except as expressly provided under this License.
Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License including any patent licenses granted under the third paragraph of section However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated a provisionally, unless and until the copyright holder explicitly and finally terminates your license, and b permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License for any work from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License.
If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance.
However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License.
Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations.
If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License.
For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation including a cross-claim or counterclaim in a lawsuit alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version.
For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent such as an express permission to practice a patent or covenant not to sue for patent infringement. To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either 1 cause the Corresponding Source to be so available, or 2 arrange to deprive yourself of the benefit of the patent license for this particular work, or 3 arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients.
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License.
You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license a in connection with copies of the covered work conveyed by you or copies made from those copies , or b primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
No Surrender of Others' Freedom. If conditions are imposed on you whether by court order, agreement or otherwise that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work.
The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. Revised Versions of this License. You can view my profile or follow me via contacts. June 17, February 12, November 29, GPIOA ,.
TIM2 ,. GPIOB ,. TIM3 ,. TIM4 ,. Like this: Like Loading Search The Blog Search for:. Sorry, your blog cannot share posts by email. Previous Tutorial. Tutorial Next Tutorial. So now let us start. You can look at a board and if the board has 16MHz crystal you became sure that this board is running at 16MHz. This beast is not running at 8MHz!
Here comes the first new concept of this new domain, the PLL. The PLL stands for phased lock loop. Wait, wait, wait! From your point of view, that is a software developers point of view this is a very simple thing which multiplies the input frequency and makes it large. Learn how to make a LED based display system for jewelery stores for showing current rate of gold.
The system is operated using a IR remote and displayed digits could be updated easily using the remote. This tutorial on Digital-Wizard explains in details the complete procedure to make such a system.
Read more …. Learn how to read data from a one-wire digital temperature sensor like ds18b Recently, after tearing down a few cheap Chinese products, I found that most of them had an STM8 microcontroller inside it. The IC is not only cheap but also packed it with lots of features and options making it suitable to be used in many different applications.
For instance, the STM8S series of controllers which we will learn in this tutorial series is a general-purpose controller but there are other series like the STM8A for Automotive Designs and STM8L for Low Power battery-powered designs which extends the application of these controllers.
The reason for getting started with this specific part number is just for its price to performance factor. Who would not be intrigued? Also, the STM8SF3P6 is widely popular, and hence as a beginner, you will find enough support if you need help outside the tutorials.
Starting from this, we will have a sequence of tutorials, similar to the PIC Programming Tutorials where we will learn how to program this controller from a basic blink to various display and sensor interfacing.
Now that we have deicide the microcontroller, we will have to select hardware and software development tools to begin our learning process. There are many options, here I have selected the ones that are free to use and easily available to everyone. The board only consists of the bare minimum components that are required to begin development. It is breadboard friendly and suitable for compact applications.
The internal circuit diagram for the development board is shown below. Taking a closer look, you will notice, apart from the STM8SF3p6 controller, we have a reset button to reset the controller. The controller can also be made to operate on 5V if required. The different parts on the controller are marked below. We also have 4 programmer pins namely 3. There are many variants metal, plastic, gold, pink, bare board of this ST-LINK v2 board and all serve the same purpose.
Mine is shown below but you can use any type of ST-LINK programmer , the pinout will differ, so just make sure you read the pinouts on the casing correctly. The official tools that are available for the STM8 Microcontroller are shown in the below image. It can only generate pin mapping for visualization purposes and might come in handy if you are porting your code from one controller to another.
Other than that, I would not use it. For the IDE and Compiler, we have a lot of options to choose from. Similarly, for the Compiler, we will be using the Cosmic C Compiler , again only because it is totally free. Another reason for choosing this IDE and Compiler is that, once we get familiar with the environment, it should be easy to use any other 8-bit Microcontroller from ST without much effort.
It will be integrated in the IDE itself, helping us to quickly program and debug.
