Hello, 

Is TIM_TimeBase example project supposed to output PWM on PA6, PA7, PB0, and PB1?

    Perhaps you can narrow that down to a specific STM32 family and board?

    Hi mesal.sel,

    There is no PWM output for this example.

    Based on the readme file, there is only an output on PD12 (When the counter value reaches the auto-reload register value, the TIM upadate interrupt is generated and, in the handler routine, PD.12 is toggled with the frequency 0.5Hz).

    Hi Mayla,

    Is toggling PD.12 equivalent to a very slow PWM (i.e. with 0.25 Hz frequency)

    Should I expect PD.12 to transition at (t=0, t=2s, t=4s ...)
