Is it possible to use Timer 3 in input capture mode on channel 1 and output compare mode on channel 3 simultaneously on STM32F103?

Hello Clive One,

I see from the diagram for the general-purpose timers (in the RM0008 Reference Manual for the STM32F1xx) that each channel has its own capture/compare register.  This is good because I want to capture the time between successive events on channel 1 while simultaneously producing a timebase time tick on channel 3.  The prescaler and period of this timer are selected to produce a roll-over period that is correct for the timebase tick on channel 3 while simultaneously producing a timing resolution sufficient for measuring the time between events on channel 1.  

Since the two applications are entirely separate,  I don't have to deal any operations that depend on both of them.

However, your reply prompted me to do a little more digging into both the source code and the reference manual, whereupon it dawned on me that I was looking for a rollover of the timer that was independent of the channel or mode.  As a result, I found HAL_TIM_PeriodElapsedCallback which of course was a solution to my problem.  

Thank you for your help. It is much appreciated.  Now I just need to find out how I can mark this question as 'closed'.

Best regards,

Peter
