Prototype release firmware for CAN Gateway hardware v02
Features:
- Receives CAN traffic at 250kbps on up to 6 busses simultaneously
- Logs received CAN frames on inserted SD card
- Keeps time and timestamps logs using on-board RTC. Set Unix epoch time in the Serial debug menu.
- CAN traffic live view is available over Serial in the debug menu.
- Alerts when CAN frames are dropped.
Note:
- This firmware does not meet "bulletproof" timing for all 6 busses at 250kbps (will drop CAN frames if all busses are fully saturated)
- Release binary limits log file size to 200MB (at which point a new file begins)
- Power the board for 24 hours before setting the time in order to charge the RTC backup battery
To use the flash script:
- Supply 6.5-36VDC to the CAN Gateway screw terminals (the board is not powered through the USB port)
- Connect the CAN Gateway to your computer using a USB-C cable
- Download and extract the release .zip file
- Edit flash_fw.bat
- Change
set COM_PORT=COM3to match the serial port assigned to the CAN Gateway hardware - Run flash_fw.bat
