![]() ![]() Then build it with: ninja Build with NinjaĪn easy way to switch between the two build systems or to start from scratch is to delete the content of the ‘build’ folder. If using ninja: call CMake with the following command line: cmake -DCMAKE_MAKE_PROGRAM="ninja.exe" -G "Ninja". If using make: call CMake to generate the make files: cmake -DCMAKE_MAKE_PROGRAM="make.exe" -G "Unix Makefiles". Open a terminal in the build output folder: Open Terminal (or Console/PowerShell) With CMake it is a two stage process: running CMake to create (or configure) the make or ninja files and then I use ‘make’ or ‘ninja’ to build it. Actually we need to ‘configure’ it first. CMakeList in Visual Studio Code Configure This completes setting up the configuration for the build. Set(TOOLCHAIN_PREFIX $ PRIVATE ): list of linker options Set(ARM_TOOLCHAIN_DIR "C:/Program Files (x86)/GNU Arm Embedded Toolchain/10 2020-q4-major/bin") I have named it arm-none-eabi-gcc.cmake and placed it in the project root folder. A simple and easy way is to to add a the following file to the project. CMake needs some information where to find the tools. I’m going to use CMake with Make to build the project. The next steps are about compiling and linking. Proposed Directory Structure Startup, System and Linker filesįrom the SDK copy the system, startup and linker files to the project folder. For the rest of the article I’m going to use that structure. Everything in this folder can be disposed/deleted/cleaned as it built from the sources.Īgain, it is up to you. build: Scratch, holds all the generated build files, object files and executable.src: application source files including main file.device: device specific header files, system initialization, startup code and linker file.CMSIS: contains the ARM CMSIS header files.My preferred ‘standard’ organization is using the following folders: It is really up to you how you organize the files. I recommend to organize files in folders. Implement the main function, then save it (CTRL+S): Folders This folder now shows up in the workspace: Main Use File > Add Folder to Workspace … Menu to add folderīrowse to an existing new (empty) folder or simply create one from the dialog:īelow I have created a new ‘FRDM-K22F_Simple’ folder and then add it: In the most simple case a workspace just contains a folder which is the folder for the project. In simple words, a workspace is a collection of Folders open in the IDE. Similar to other IDEs, VSC is using the concept of a ‘workspace’. Colors? Colors!īefore I forget: Something very easy to start with: here is where you can change the color theme in Visual Studio Code to whatever you like: Change Color Theme Workspace and Project(s) The advantage of using such an SDK is that you have the freedom of choice and complete control, without the ‘lock-in’ into custom frameworks and dependencies from the beginning. Make sure you have the SDK for the GNU gcc: MCUXpresso SDK with files for GCC ARM Embedded NXP provides all the needed files in the MCUXpresso SDK. from my GitHub) or from the SDK/examples provided by the vendor of your silicon device, e.g. The other items you can get from examples (e.g. ![]() Item one is something you easily can write yourself. Linker File: this defines the memory mapping plus how the application shall be linked together.In addition it provides header files for the memory mapped device registers and peripherals like I2C, SPI, … System: In a CMSIS environment, the startup code calls a system initialization callback (SystemInit() to set clocks, configure watchdog, …).Startup code: this gets executed out of reset, initializes the system, memory, library and jumps to main().Main: a file with the application main entry point (main()).And all the files used/created here are on GitHub: SDKīeside of the compiler/linker/debugger you need some minimal files to build a project: I’m not going to use ‘fancy’ wizards or frameworks, I’m just using the base tools for a reason: to keep things simple.ĭon’t worry: it is easy. It is about creating a main file, adding a startup code and build it as a project. It is about using the most essential tools to do the job, without the need for other ‘frameworks’ unless you really want them. The goal is is to create something simple and easy you can use for your own projects. Part 2 is about creating a very simple C project. In Part 1 we have installed the necessary tools, so make sure you have completed that part. Building with Visual Studio a simple ARM Cortex-M Project (NXP K22FN512) Outline In this part I’m going to show how to create and build a project using CMake running Make or Ninja as build system. This is the second part of series or articles how to use the Microsoft Visual Studio Code for embedded development on ARM Cortex-M.
