boelle HiWould it be much trouble to add the STM32F103 to the list of processors?It also an ARM chip like the DUE
Repetier Can't say for sure. I've seen there is a Arduino compatibility library for STM not sure if that one is included. If it is compatible enough all that remains in modifying HAL.h/cpp to the special needs as number of timers or so may differ. But I think most can be used as it is.
