Issues should be opened here if they affect the code you write (e.g., \"I would like to be able to do X with PROS,\" or \"when I call X doesn't work as I expect\")\n - [purduesigbots/pros-cli](https://github.com/purduesigbots/pros-cli): the repository containing the source code for the command line interface (CLI). Issues should be opened here if they concern the PROS CLI (e.g., problems with commands like `pros make`), as well as project creation and management.\n - [purduesigbots/pros-atom](https://github.com/purduesigbots/pros-vsc): the repository containing the source code for the VSCode extension. Issues should be opened here if they concern the coding experience within VSCode (e.g., \"there is no button to do X,\" or \"the linter is spamming my interface with errors\").\n - [purduesigbots/pros-docs](https://github.com/purduesigbots/pros-docs): the repository containing the source code for [our documentation website](https://pros.cs.purdue.edu). Issues should be opened here if they concern available documentation (e.g., \"there is not guide on using ,\" or \"the documentation says to do X, but only Y works\")\n- **Verify the bug lies in PROS.** We receive quite a few reports that are due to bugs in user code, not the kernel.\n- Ensure the bug wasn't already reported by searching GitHub [issues](https://github.com/purduesigbots/pros/issues)\n- If you're unable to find an issue, [open](https://github.com/purduesigbots/pros/issues/new) a new one.\n\n**Did you patch a bug or add a new feature?**\n1. [Fork](https://github.com/purduesigbots/pros/fork) and clone the repository\n2. Create a new branch: `git checkout -b my-branch-name`\n3. Make your changes.\n4. Push to your fork and submit a pull request.\n5. Wait for your pull request to be reviewed. In order to ensure that the PROS kernel is stable, we take extra time to test pull requests. As a result, your pull request may take some time to be merged into master.\n\nHere are a few tips that can help expedite your pull request being accepted:\n- Follow existing code's style.\n- Document why you made the changes you did.\n- Keep your change as focused as possible. If you have multiple independent changes, make a pull request for each.\n- If you did some testing, describe your procedure and results.\n- If you're fixing an issue, reference it by number.\n" }, { "path": ".github/ISSUE_TEMPLATE.md", "content": "#### Expected Behavior:\n\n\n#### Actual Behavior:\n\n\n#### Steps to reproduce:\n\n\n#### System information:\nPlatform: \nPROS Kernel Version: \n\n#### Additional Information\n\n\n#### Screenshots/Output Dumps/Stack Traces\n" }, { "path": ".github/PULL_REQUEST_TEMPLATE.md", "content": "#### Summary:\n\n\n#### Motivation:\n\n\n##### References (optional):\n\n\n#### Test Plan:\n\n\n- [ ] test item\n" }, { "path": ".gitignore", "content": ".vscode/\n.idea/\nbin/\n.*.sw*\ntemplate/\nversion\ncquery_log.txt\ncompile_commands.json\n.ccls-cache/\n.ccls\ntemp.log\ntemp.errors\n.d/\n.clangd/\n.cache/\n.DS_Store\n" }, { "path": ".gitmodules", "content": "[submodule \"firmware/libv5rts\"]\n\tpath = firmware/libv5rts\n\turl = git@github.com:purduesigbots/libv5rts.git\n\tignore = dirty\n" }, { "path": "LICENSE", "content": "PROS 4.0 contains modified or linked source code from the following packages:\n - FreeRTOS (src/rtos/LICENSE)\n\nUnless otherwise specified, PROS 4.0 is distributed under the Mozilla Public\nLicense Version 2.0, reproduced below:\n\nMozilla Public License Version 2.0\n==================================\n\n1.

PROS is built with developers in mind and with a focus on providing an environment for industry-applicable experience.\n\nPrimary maintenance of PROS is done by students at Purdue University through [Purdue ACM SIGBots](http://purduesigbots.com). Inspiration for this project came from several computer science and engineering students itching to write code for the extended autonomous period. We created PROS to leverage this opportunity.\n\nAll PROS development is open sourced and available for the community to inspect. We believe that sharing source improves PROS through community contributions and allows students to learn by example.\n\nPROS is built using the GCC toolchain and standard C/C++ practices (C23 & C++23 w/GNU extensions) to make the learning curve small. Structures, pointers, dynamic memory allocation, and function pointers are all available. Additionally, code is run on bare metal, allowing you to take full advantage of the microcontroller's power.\n\nYou can develop code on Windows, OS X, or Linux. Code is compiled using GCC and the PROS CLI is available on most operating systems. The PROS development team makes distributions for Windows, OS X, and Debian-based Linux distributions.\n\nThe PROS team develops a plugin for Atom to making developing projects in PROS the best possible experience. The highly customizable editor designed for the 21st century enables students to learn how to code in a modern environment.\n\n### What's the difference between PROS 4 and 3?\nPROS 4 is a Kernel upgrade from PROS 4 to both decrease the size of the base Kernel, and provide utilities such as the base device class and liblvgl that makes it easier for both users and library writers to customize their PROS projects. This version also moves all documentation to a doxygen site rather than a Sphinx documentation page. \n\n### What's the difference between PROS 2 and PROS 3?\nPROS 2 refers to the kernel that runs on the [VEX Arm Cortex-based Microcontroller](https://www.vexrobotics.com/276-2194.html). The source for this kernel is still available on the `cortex-master` branch. The future development for this version of the PROS kernel will be focused on maintenance and critical bugfixes.\n\nPROS 3 refers to the kernel that runs on the [VEX V5](https://www.vexrobotics.com/vexedr/v5) microcontroller platform. The majority of our development focus will be on this version of the PROS kernel.\n\n### Does PROS support C++?\n- PROS 3.x and 4.x (V5) officially supports C++. We're still working on enabling all of the features of C++ (particularly in the I/O area).\n- PROS 2.x (Cortex) does not officially support C++. Some users have found ways around this, but be warned: we will not be able to help if you run into issues doing this.\n\n### Cool, how do I get it?\nPay a visit to our website, [pros.cs.purdue.edu](https://pros.cs.purdue.edu), to download our latest installer or view installation instructions for your preferred platform.\n\n### How do I use it?\nWe have a number of resources available on our website, including\n- [A basic tutorial to get you acquainted with the PROS ecosystem](https://pros.cs.purdue.edu/v5/getting-started/new-users.html)\n- [A series of tutorials on how to use some of the more advanced features of PROS](https://pros.cs.purdue.edu/v5/tutorials/index.html)\n- [Extensive documentation on the kernel's API](https://pros.cs.purdue.edu/v5/api/index.html)\n\n### I still have questions!\nDrop us a line\n- at pros_development@cs.purdue.edu\n- on the [VEX Forum](https://www.vexforum.com/)\n- on [VEX Teams of the World Discord](https://discord.gg/xddjWGj)\n\n### I think I found a bug!\nWe maintain GitHub repositories for the three major components of the PROS ecosystem:\n- The Command Line Interface (cli) at [purduesigbots/pros-cli](https://github.com/purduesigbots/pros-cli)\n- The VS Code plugin at [purduesigbots/pros-vsc](https://github.com/purduesigbots/pros-vsc)\n- The kernel [here](https://github.com/purduesigbots/pros)\n\nIf you find a problem with our documentation or tutorials, we have a repository for that, too, at [purduesigbots/pros-docs](https://github.com/purduesigbots/pros-docs).\n\n### Hey! Why can't I build the PROS kernel?\nThe PROS kernel depends on VEX's proprietary Software Development Kit (SDK), which is not publicly available.\n" }, { "path": "STYLEGUIDE.md", "content": "# PROS Kernel Styleguide\n\nMaintaining a consistent coding style throughout the PROS kernel is important for future developers and students to learn about the PROS kernel. An inconsistent style can lead to confusion for everyone.\n\nThe PROS style is based on the Google C++ coding style (with some modifications noted a bit farther down), which allows `clang-format` to be used on every file and get correctly formatted code.\n\nSome additional notes follow:\n\n## File extensions\n- C source files will have the extension `.c`\n- C++ source files will have the extension `.cpp`\n- C header files will have the extension `.h`\n- C++ header files will have the extension `.hpp`\n\n## Naming Conventions\nThe PROS kernel follows these naming conventions:\n\n- Structures: `structname_s`:\n - Structure members: these do not have any special convention, as you will never see a structure member without seeing that it is in a structure.\n- Enumerated types: `enumname_e`\n - Enumerated type members: `E_ENUMNAME_MEMBERNAME`\n\n For example, in `task_state_e`, you might have members such as `E_TASK_STATE_RUNNING`. Note that \"ENUMNAME\" can be multiple words, separated by underscores.\n- Function pointers: `funcname_fn`\n- Type definitions: append `_t` to the end of the structure/enum/function pointer name\n- C++ classes: these should be named in UpperCamelCase (also known as PascalCase)\n - Class members: use lower_snake_case as normal, and use good sense when naming\n\nThis section provides only a brief overview of the naming conventions used in the PROS kernel. For more about the motivations behind these, see section 4 (Naming) below.\n\n## Documentation\nUse Doxygen-style comments as shown in the sections below.\n\n### File-Level Comments\nThese should be placed at the very start of a file.\n```c\n/**\n * \\file filename.h\n *\n * Short description of the file\n *\n * Extended description goes here. This should explain what the functions (etc)\n * in the file contains and a general description of what they do (no specifics,\n * but they should all have something in common anyway).\n *\n * This file should not be modified by users, since it gets replaced whenever\n * a kernel upgrade occurs.\n *\n * \\copyright Copyright (c) 2017-2026, Purdue University ACM SIGBots.\n *\n * This Source Code Form is subject to the terms of the Mozilla Public\n * License, v. 2.0. If a copy of the MPL was not distributed with this\n * file, You can obtain one at http://mozilla.org/MPL/2.0/.\n */\n```\n\n### Enum-Level Comments\nThese should be placed immediately before the declaration of the enum.\n```c\n/*\n * Short description of the enum\n *\n * Extended description of the enum goes here. This should explain general usage\n * patterns for the enum.\n */\nenum my_enum {\n E_MEMBER_0, // short description of member 0 goes here.\n E_MEMBER_1, // these can be omitted if it's painfully obvious\n E_MEMBER_2, // what each is for, or if there are just so many of\n E_MEMBER_3, // them it doesn't make practical sense to\n E_MEMBER_4 // document them all.\n}\n```\n_Note: in the above example, the comments describing each member of the `enum` run together and form complete sentences for effect. Please do not do this in your code!_\n\n### Function-Level Comments\nThese should be placed immediately before the function prototype they are describing in a header file.\n\n```c\n/**\n * Brief description of the function.\n *\n * An extended description of the function (if applicable).\n *\n * This function uses the following values of errno when an error state is\n * reached:\n * ERRNO_VALUE - Description of what causes this error\n *\n * \\param parameter_name\n * The parameter description\n * \\param other_parameter_name\n * The parameter description\n *\n * \\return The description of the return value, if this is longer than one line\n * then it will wrap around under the return statement\n */\n```\n\n### Inline Implementation Comments\nSometimes it is necessary to explain a particularly complex statement or series of statements. In this case, you should use inline comments, placed either immediately before or trailing the line or lines in question. In general, prefer placing such comments before offending lines, unless the comment is quite short. These comments should start with a `//` followed by a space. If they are placed trailing a line, they should be separated from the end of the line by one space.\n```c\nfloat Q_rsqrt(float number) {\n long i;\n float x2, y;\n const float threehalfs = 1.5F;\n x2 = number * 0.5F;\n y = number;\n // perform some absolute magic on these numbers to get the inverse square root\n i = *(long*)&y; // evil floating point bit level hacking\n i = 0x5f3759df - (i >> 1); // what the [heck]?\n y = *(float*)&i;\n y = y * (threehalfs - (x2 * y * y)); // 1st iteration\n //y = y * (threehalfs - (x2 * y * y)); // 2nd iteration, this can be removed\n return y;\n}\n```\n_Note: in the above example, there is a line of code that has been commented out. This is fine to do while testing, but any commented out lines of code should be removed before any merge into the master branch takes place, unless a compelling reason can be presented for them to remain._\n\nAll that being said, try to avoid code that is so complex that it requires inline comments for its purpose to be clear.\n\n#### Notes to Other Developers (Or Yourself)\nWhen writing code, it can sometimes be useful to leave notes to other developers or to yourself in the future. Examples of these include:\n\n- `// TODO: something that should be done`\n- `// NOTE: a note about something in the code`\n - `// NB: this is the same as NOTE, but it's in Latin, so it's fancier`\n- `// HACK: used to describe a particularly nasty way of solving a problem-- could be improved, but it works for now`\n- `// FIXME: this code is broken and should be fixed`\n - `// XXX: this is like FIXME, but it's worse (note that this has also been used in the same way as HACK, so you should use that or FIXME to clarify what is meant)`\n - `// BUG: this is used to mark a line of code that is known to cause a bug. kind of like FIXME, though it may include some more specific information than FIXME would`\n\nWhile it is not strictly necessary to use these keywords in comments, they can be helpful-- modern editors (like Atom or VSCode) either highlight some of these keywords by default or have extensions that do. This can make certain comments stand out even more when developers are \"grepping\" the codebase (visually or otherwise).\n\n### Word Choice and Tense\n\nContent for the docs should follow the\n[Google Developer Documentation Style Guide](https://developers.google.com/style/),\nand the [API Reference Comments Section](https://developers.google.com/style/api-reference-comments)\nin particular.\n\nWhile the Google Style Guide should determine the vast majority of the docs' word choices,\nadditionally follow these content-specific guides:\n\n- All ports, Smart, ADI, or otherwise, should be referred to as a port, not a channel\n or pin.\n- C++ functions should be written as their full function name, without removing the\n `pros::` namespace (e.g. `pros::Motor::move`).\n- All enumerated values referenced in the code comments should be written as their\n full name per the PROS Style Guide, not the `PROS_USE_SIMPLE_NAMES` version.\n (e.g. `E_MOTOR_GEARSET_18`, not `E_MOTOR_GEARSET_18`).\n\n### C/C++ Format Guide\n\nThe PROS Coding style is based on the [Google C++ Coding Style](https://google.github.io/styleguide/cppguide.html) with the following modifications:\n\n```\nTabWidth: 2\nUseTab: ForIndentation\nColumnLimit: 120\nDerivePointerAlignment: false\nPointerAlignment: Left\nFixNamespaceComments: true\nReflowComments: true\nSortIncludes: true\nAccessModifierOffset: 0\nAllowShortBlocksOnASingleLine: false\nAllowShortCaseLabelsOnASingleLine: false\nAllowShortFunctionsOnASingleLine: Empty\n```\n" }, { "path": "VSCode.md", "content": "Use the following include paths for intellisense completion:\n\n\"${env:PROS_TOOLCHAIN}/arm-none-eabi/include\",\n\"${env:PROS_TOOLCHAIN}/lib/gcc/arm-none-eabi/6.3.1/include\",\n\"${workspaceRoot}\",\n\"${workspaceRoot}/include\"\n\nAdd \"_INTELLISENSE\" to your defines to fix certain intellisense errors that will actually compile without issue" }, { "path": "azure-build-libc.yaml", "content": "###############################################################################\n#\n# This pipeline builds newlib with the same flags as the official toolchain,\n# but adds -funwind-tables so we can have proper unwind info inside libc\n#\n###############################################################################\nvariables:\n source_url: 'https://developer.arm.com/-/media/Files/downloads/gnu-rm/8-2018q4/gcc-arm-none-eabi-8-2018-q4-major-src.tar.bz2'\n source_directory: 'gcc-arm-none-eabi-8-2018-q4-major'\n\njobs:\n- job: BuildLibc\n pool:\n vmImage: 'ubuntu-16.04'\n timeoutInMinutes: 0\n steps:\n -

It is safe for the\n * writer and reader to be different tasks or interrupts, but, unlike other\n * FreeRTOS objects, it is not safe to have multiple different writers or\n * multiple different readers.  If there are to be multiple different writers\n * then the application writer must place each call to a writing API function\n * (such as msg_buf_send()) inside a critical section and set the send\n * block time to 0.  Likewise, if there are to be multiple different readers\n * then the application writer must place each call to a reading API function\n * (such as xMessageBufferRead()) inside a critical section and set the receive\n * block time to 0.\n *\n * Use msg_buf_recv() to read from a message buffer from a task.  Use\n * xMessageBufferReceiveFromISR() to read from a message buffer from an\n * interrupt service routine (ISR).\n *\n * @param xMessageBuffer The handle of the message buffer from which a message\n * is being received.\n *\n * @param pvRxData A pointer to the buffer into which the received message is\n * to be copied.\n *\n * @param xBufferLengthBytes The length of the buffer pointed to by the pvRxData\n * parameter.  This sets the maximum length of the message that can be received.\n * If xBufferLengthBytes is too small to hold the next message then the message\n * will be left in the message buffer and 0 will be returned.\n *\n * @param pxHigherPriorityTaskWoken  It is possible that a message buffer will\n * have a task blocked on it waiting for space to become available.  Calling\n * xMessageBufferReceiveFromISR() can make space available, and so cause a task\n * that is waiting for space to leave the Blocked state.  If calling\n * xMessageBufferReceiveFromISR() causes a task to leave the Blocked state, and\n * the unblocked task has a priority higher than the currently executing task\n * (the task that was interrupted), then, internally,\n * xMessageBufferReceiveFromISR() will set *pxHigherPriorityTaskWoken to pdTRUE.\n * If xMessageBufferReceiveFromISR() sets this value to pdTRUE, then normally a\n * context switch should be performed before the interrupt is exited.  That will\n * ensure the interrupt returns directly to the highest priority Ready state\n * task.  *pxHigherPriorityTaskWoken should be set to pdFALSE before it is\n * passed into the function.  See the code example below for an example.\n *\n * @return The length, in bytes, of the message read from the message buffer, if\n * any.\n *\n * Example use:\n
\n// A message buffer that has already been created.\nMessageBuffer_t xMessageBuffer;\n\nvoid vAnInterruptServiceRoutine( void )\n{\nuint8_t ucRxData[ 20 ];\nsize_t xReceivedBytes;\nint32_t xHigherPriorityTaskWoken = pdFALSE;  // Initialised to pdFALSE.\n\n    // Receive the next message from the message buffer.\n    xReceivedBytes = xMessageBufferReceiveFromISR( xMessageBuffer,\n                                                  ( void * ) ucRxData,\n                                                  sizeof( ucRxData ),\n                                                  &xHigherPriorityTaskWoken );\n\n    if( xReceivedBytes > 0 )\n    {\n        // A ucRxData contains a message that is xReceivedBytes long.  Process\n        // the message here....\n    }\n\n    // If xHigherPriorityTaskWoken was set to pdTRUE inside\n    // xMessageBufferReceiveFromISR() then a task that has a priority above the\n    // priority of the currently executing task was unblocked and a context\n    // switch should be performed to ensure the ISR returns to the unblocked\n    // task.  In most FreeRTOS ports this is done by simply passing\n    // xHigherPriorityTaskWoken into taskYIELD_FROM_ISR(), which will test the\n    // variables value, and perform the context switch if necessary.

\n *\n * Receives bytes from a stream buffer.\n *\n * ***NOTE***:  Uniquely among FreeRTOS objects, the stream buffer\n * implementation (so also the message buffer implementation, as message buffers\n * are built on top of stream buffers) assumes there is only one task or\n * interrupt that will write to the buffer (the writer), and only one task or\n * interrupt that will read from the buffer (the reader).  It is safe for the\n * writer and reader to be different tasks or interrupts, but, unlike other\n * FreeRTOS objects, it is not safe to have multiple different writers or\n * multiple different readers.  If there are to be multiple different writers\n * then the application writer must place each call to a writing API function\n * (such as stream_buf_send()) inside a critical section and set the send\n * block time to 0.  Likewise, if there are to be multiple different readers\n * then the application writer must place each call to a reading API function\n * (such as xStreamBufferRead()) inside a critical section and set the receive\n * block time to 0.\n *\n * Use stream_buf_recv() to read from a stream buffer from a task.  Use\n * xStreamBufferReceiveFromISR() to read from a stream buffer from an\n * interrupt service routine (ISR).\n *\n * @param xStreamBuffer The handle of the stream buffer from which bytes are to\n * be received.\n *\n * @param pvRxData A pointer to the buffer into which the received bytes will be\n * copied.\n *\n * @param xBufferLengthBytes The length of the buffer pointed to by the\n * pvRxData parameter.  This sets the maximum number of bytes to receive in one\n * call.  stream_buf_recv will return as many bytes as possible up to a\n * maximum set by xBufferLengthBytes.\n *\n * @param xTicksToWait The maximum amount of time the task should remain in the\n * Blocked state to wait for data to become available if the stream buffer is\n * empty.  stream_buf_recv() will return immediately if xTicksToWait is\n * zero.  The block time is specified in tick periods, so the absolute time it\n * represents is dependent on the tick frequency.  The macro pdMS_TO_TICKS() can\n * be used to convert a time specified in milliseconds into a time specified in\n * ticks.  Setting xTicksToWait to portMAX_DELAY will cause the task to wait\n * indefinitely (without timing out), provided INCLUDE_vTaskSuspend is set to 1\n * in FreeRTOSConfig.h.

    "content": "## The FreeRTOS Kernel Library\n\n__Note: modifiying these files may break PROS or make PROS unstable__\n\n_This file serves as an introduction to how PROS uses FreeRTOS if you're just_\n_getting started with development of the PROS kernel. It also contains some_\n_notes from configuring FreeRTOS to work with the V5._\n\nPROS 3 uses FreeRTOS 9.0.0 to implement scheduling, queues, and lists - the \nbarebones of an operating system. In some respects, FreeRTOS could be thought of\nas a C library that we have ported to the V5. It of course does more significant\nwork that a typical application library.\nSince computer architectures are different and FreeRTOS aims to work with many\nembedded architectures, some work must be done to let FreeRTOS work with the \nhardware.\n\nFreeRTOS provides many demo projects and the developers recommend modifying one \nof the projects to suit the needs of the project. Since the V5 is Zynq-7000 board,\nwe're modifying the Cortex\\_A9\\_Zynq\\_ZC702 demo.\n\nYou should read some of FreeRTOS's documentation and/or take an equivalent of \nPurdue's CS250 (Computer Architecture) and CS354 (Operating Systems) for \nrequisite background knowledge. For more info about the Zynq/A9 port, see \nFreeRTOS's documentation on [Zynq](http://www.freertos.org/RTOS-Xilinx-Zynq.html) \nand the [A9](http://www.freertos.org/Using-FreeRTOS-on-Cortex-A-Embedded-Processors.html).\n\n## Modifications to FreeRTOS\nWe've somewhat significantly refactored the FreeRTOS kernel so that any FreeRTOS\nfunctions used within PROS align with the PROS coding style. See refactor.tsv in\nthis directory.\n\nWe've removed the use of `int32_t` and `uint32_t` from any public facing\nAPI since we felt it unnecessary. Additionally, all variables pertaining to ticks\non the PROS internal or public facing APIs have become millisecond precision, and \nthe conversion done immediately upon entering the functiion.\n\n"

sem_t mutex_create( void )
\n *\n * Creates a new mutex type semaphore instance, and returns a handle by which\n * the new mutex can be referenced.\n *\n * Internally, within the FreeRTOS implementation, mutex semaphores use a block\n * of memory, in which the mutex structure is stored.
