Hello,now I try some equipment control which has function that watching some fault vibration, with using displacement sensor & ADC.while I want to reduce ADC output noise and found that FMAC works pretty good.but now the problem is, when ADC-DMA outp...

Once I posted the issue about 2 PWM outputs synchronize.https://community.st.com/t5/stm32-mcus-products/2-pwm-outputs-is-this-possible/td-p/587654 Now every 1st time after power on (or CPU reset if connected with IDE/Programmer) it works exactlly syn...

now I'm about to try 2 PWM outputs on STM32G4, one is 1/2 time-base delayed from another one.I think that it is difficult with using only 1 timer, and if using 2, is it possible?maybe like following.. using TIM2 & TIM3 for example, both are PWM gen...

hello @waclawek.jan thank you for your advise, and now it was solved.I used HAL_TIM_PWM_Stop() before, but it reset CR1.CEN I found.then I modify it not to reset CR1.CEN as followings, and works as well expected.regards.

represent the problem by diagram. see attached 'diagram1.png'. >>now I'm trying some TIM initialization made before restart, but still not work as expected.following is one of my trial.I wonder that the answer is close here but not found now.. -call ...

hello @Issamos thanks you for informing, but no hint about my problem is there.1st time to start synchronizing PWM output is completely works, no doubt.but problem is after stop PWM output and then restart it.now I'm trying some TIM initialization ma...

hello @Jason_fx >I can't find the ___HAL_TIM_SET_COMPARE function on the PWMOutput sample codeyou can find in stm32??xx_hal_tim.h. (?? = depends on your project, I guess) One important thing that duty must be 0 ~ 1 (or can say 0 ~ 100%).is your sampl...

hello, @Jason_fxoff course join the codes into your main() or some applicable place by yourself.and, if the Counter Period in your project is for example "999" (=1000-1), I mean V_TIM_Cbase = 1000,then it should be refered in the code which I show yo...
