I've been trying to use the TIM2_CH1 function for PA15 but without success on a Nucleo-L073RZ. This function works OK on pins PA0 and PA5. Also PA15 works if set in GPIO output mode.Errata document does not state anything about this pin.Could you con...

External oscillator: MC-146 32.7780KA-A0Load capacitors used: CL_1 = CL_2 = 8pFWith Drive Level of Low the application works. I would like to obtain better understanding of how the G_m_crit_max is connected to the CL. I've had a look at AN2867 - Osc...

Oh! That was it. For some reason I connected the "_0_7" part of the name to the Alternate Functions which are also (AF_0..AF_7).

With the debugger I can see that while PA5's Alternate function can be set to AF5, PA15's cannot (AFRL register). The below snippets shows the cases with each pin. Breakpoint 1 holds the initial state and Breakpoint 2 the initialization. Note that PA...
