The STM32's have a possibility to bring out a clock signal called `MCO`. It takes one of the selected clock sources, puts it through a divider and brings it out to a GPIO pin. I use it to spare a crystal in a design. Be aware that when having a long wire attached to the pin, you create a nice transm...

Dear all, Before diving into a night of debugging with the STM32L476RG port: Are there instances that need to be reinitialised after the system is woken up from a pyb.stop()? Same measurement code: - using a loop that fires a measurement using pyb.ADC() every 2 seconds --> works - using rtc.wakeup(2...
