Hi! I am a beginner in programming STM32f4 and that is my biggest problem, I think...
I am working now on the project where I need do profile the velocity of servo motor (i.e. trapezoidal velocity)... So I need to control the number of pulses I have sent and periodically update the frequency of signal...
So I have a question: Can I just change just: TIMx->ARR, PSC and CCRx registers in the PWM signal generator...? Or for example I must turn of timer first, and then update parameters...?
Thanks a lot for any hints, best regards,
P.S Have You any example projects of velocity profiling in C...? Or any tutorial of doing that on uC... Thanks again...
Hi!
Thanks a lot for Your fast replay. I thought that it is possible but I wasn't sure...
I would have one more question: I need to control the number of pulses I have sent in PWM channel to know position of serwo motor... Could You suggest me a few method which I can use to do that...? And which is the best...?
Now I am using 2 timers linked by wire: one in PWM Out Mode and the other in Input Capture Mode with External CLK on this pin. It is working "quite good" but I dont know if it is the best method to implement...
Thanks for any advice,
