CMake template for STM32 projects

STM32 CMake Project Template

This template has been tested in Linux. Additional adjustments may be required for use in Windows.

How to compile code

Prerequisite:

This cmake setup assumes the gcc-arm-none-eabi toolchain has been set up correctly in your system.

Generally there are two ways to set up the toolchain:

1. Install using the package manager

   $ sudo apt install gcc-arm-none-eabi
   

2. Download the toolchain binaries and add its directory to system path

• Find the binaries from the website:

  https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads

• Add the path in .bashrc (for example, if you put the extracted files at /opt/gcc-arm-none-eabi-7-2017-q4-major-linux)

  $ export PATH=/opt/gcc-arm-none-eabi-7-2017-q4-major-linux/bin:$PATH
  

• Make sure you can invoke the toolchain from a terminal

  $ arm-none-eabi-gcc -v
  

Now you can try to compile the sample project using the cmake template.

$ cd <path-of-this-repo>
$ mkdir build && cd build
$ cmake ..
$ make -j

If the "cmake .." step runs successfully, you should see something similar to the below screenshot:

Then you can continue to actually compile the code and you can expect a similar result:

You can find the compiled .elf, .hex and .bin binary files in "build/src".
