Hello Jan,as you suggested, I set a trap detecting the condition of prescaler different from 32.I also set a trap inside the HAL_RTC_Init function.However after two days of testing I had no luck and no GPIO were asserted. Are there some other conditi...

Hello Jan,Thank you for your answer, however I'm not talking about Cube generated code as I'm working in bare Eclipse. I only downloaded the Hal layer from ST, where no error is returned when trying to configure internal channel when ADC is already e...
