dmn-edc32

DMN-EDC diesel engine control (Bosch VE and inline pumps) for STM32. Current status: porting from avr (Arduino) in progress. For more information, contact syncro16@outlook.com.

Tools needed

• stm32f334 board (nucleo or discovery version)
• openocd (debugger interface over usb)
• gcc-arm toolchain
• gdb recommended for uploading binary. Other ways may work, but they might erase entire flash, including the last 3 pages, which is reserved for saved user settings.
• terminal emulator (screen is fine)
• STM32CubeMX if you want to reconfigure some lowlevel HAL things (automatically generates main.c and some other files)

Compiling

Manually check Makefile in sources directory, edit BINPATH for your gcc-arm toolchain location. Type make to compile sources.

Communicating with openocd

Start openocd with openocd -f util/stm32f334discovery.cfg

Uploading binary with GDB

Go to sources/build directory aAnd start gdb with command arm-none-eabi-gdb dmn-edc32.elf --eval-command="target remote localhost:3333"

• Type load to load binary to stm32 board
• Type c to start the program
• You may stop the program execution in with ctrl-c

Serial communucation

While program is running on board, you can connect it with serial port. Port name will vary depending your operating system (/dev/ttyUSBx, COMx, etc..). In my system (macOS), it appears at /dev/tty.usbmodem1413.

• Type screen /dev/tty.usbmodem1413 115200 to open connection.
• Type ctrl-k and y to exit from screen.

Daughter card for communicating with engine electronics

Development in progress. Available soon. See docs directory for updates.
