CANtact Firmware

This repository contains sources for CANtact firmware.

Building

Firmware builds with GCC. Specifically, you will need gcc-arm-none-eabi, which is packaged for Windows, OS X, and Linux on Launchpad. Download for your system and add the bin folder to your PATH.

With that done, you should be able to compile using make. If you are compiling for a device that has no external crystal, compile with make INTERNAL_OSCILLATOR=1.

Flashing & Debugging

Debugging and flashing can be done with any STM32 Discovery board as a programmer. You can also use other tools that support SWD.

To use an STM32 Discovery, run OpenOCD using the stm32f0x.cfg file: openocd -f fw/stm32f0x.cfg.

With OpenOCD running, arm-none-eabi-gdb can be used to load code and debug.
