Hi there,I would like to execute some code in an interrupt handler when the pulse value for TIM16 is reached. But for some reason, none of the interrupts provided by HAL seem to trigger for this event.I have setup the timer using the configuration to...

I'm following this tutorial on DMA (https://www.youtube.com/watch?v=EsZLgqhqfO0) which at the end shows how to set up the DMA peripheral to continuously perform ADC conversions and store the results in a circular buffer.I am using an STM32F051C6 (dif...

If I recall correctly:HAL_TIM_PeriodElapsedCallback is called when the timer reaches the value stored in the 'reload register' (This is when the timer 'updates' and determines the frequency of your PWM signal)As TDK has said above HAL_TIM_PWM_PulseFi...

It makes so much more sense now! Thanks so much!

Thanks, turns out I was clocking the DMA at 8MHz while the ADC was operating on 14MHz.

So I think I've figured it out.The issue was my clock configuration. I was using 8MHz to clock the DMA peripheral, while using the asynchronous internal 14MHz clock source for the ADC. Hence why the ADC kept getting over-run and why the DMA ultimatel...

So I have narrowed the problem further.It seems that the ADC is being over-run.If I change the ADC clock source to 'synchronous clock mode' the code works fine, but if I use asynchronous there ADC is overrun and the DMA freezes up.I'm not sure why th...
