Hardware and firmware for the CANtact CAN bus tool.

CANtact

This repository contains the design files for CANtact, an open source CAN bus tool.

Firmware

Firmware is located in the fw/ folder. It contains the sources for this project, and all the driver sources for the STM32 microcontroller.

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.

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.

Hardware

The hardware design files are in the hw/ folder. These files are editable with KiCad.
