folder structure

code

STM32 Firmware projects based on libopencm3. There is one for the STM32F4-Discovery Board for prototyping and testing code and one for the finished custom PCB with a STM32L1.

• Firmware library: libopencm3.
• Display driver: u8g2 (0.96" 128x64 OLED display, SSD1306, I2C)

cad

3D models of the housing as source (FreeCad) as well as the STLs for direct 3D printing

pcb

Design files for the PCB (made in KiCad) as well as the Gerber files

Building the firmware

Make sure you have the GNU ARM Embedded toolchain installed. Also, building is much easier on a Linux machine. Windows is still porssible but requires a few more steps, see the linopencm3 repository for details)

After cloning the repository, make sure to run git submodule init and git submodule update in order to pull the libopencm3 submodule. Then go to the code/libopencm3 directory and run make TARGETS=stm32/f4 (or TARGETS=STM32/l1, depending on which project you want to use). This builds the libopencm3 library. After that, go to the firmware directory, for example ´code/f4discovery´ and run make
