I am trying to set up a timer on my STM32F103 Blue Pill with Arduino framework
platform = ststm32
board = bluepill_f103c8
framework = arduino
upload_protocol = stlink
Having a problem here:
The compiler shows an error, TIMER_CH1 is not defined.
What could I have missed? I have included HardwareTimer.h
Have also tried several other code examples with the HardwareTimer instance, but none of them I was able to compile.
And how can the interrupt priority changed with NVIC_SetPriority()?
Does not appear in the STM32 core (Search · TIMER_CH1 · GitHub), but appears in the Maple core (Search · TIMER_CH1 · GitHub). If your intention is to develop for the Maple core, see docs.
Thanks a lot for your hint. Where can I find the functions in STM32core to set the timers?
See the Wiki that is linked in their repo: HardwareTimer library · stm32duino/wiki Wiki · GitHub. I think the function you’re looking for is
void setCaptureCompare(uint32_t channel, uint32_t compare, TimerCompareFormat_t format = TICK_COMPARE_FORMAT); // set Compare register value of specified channel depending on format provided
