Arduino for STM32

Thanks. About ADC sampling it can be redefined using the build_opt.h: https://github.com/stm32duino/Arduino_Core_STM32/blob/6dec3b655fda17ba0f33cf12cef16b64d0333abd/libraries/SrcWrapper/src/stm32/analog.cpp#L33-L47 Simply defined ADC_SAMPLINGTIME with the value you want ;) Help..! I tried every way...
