This repository contains sources for CANtact firmware.
Documentation can be found on the Linklayer Wiki.
LD4: "RED" led (can frame rx/tx) LD5: "Green" led (status)
CanBUS connection:
PB9: CAN_TX
PB8: CAN_RX
Firmware runs from internal HSI48 oscillator. The connectors are nicely aligned together in top right of the board, on P2 connector. GND, PB9, PB8, VCC is available in a single row.
Tested with: Waveshare CAN breakout board
USB connection via USB USER connector on the board
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.
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.
