git clone --recursive https://github.com/STMicroelectronics/STM32CubeC0
One demo sends ABCD to the bus at 1 megabits when the user button is pressed.
Makefile
Create a GNU Makefile with EWP.py.
cd STM32CubeC0/Projects/NUCLEO-C092RC/Examples/FDCAN/FDCAN_Classic_Frame_Networking ewp.py -p1 . EWARM/FDCAN_Classic_Frame_Networking.ewp FDCAN_Classic_Frame_Networking > Makefile
Edit the makefile changing FIXME ARCH to cortex-m0 and FPU to soft.
vi Makefile
