I saw a similar post here that is related to my problem. But unlike in this post, I want to read to adc channel inside a timer interrupt which has a sampling rate of 50KHz. How do I do it? I tried following this post and but adding start and stop adc...

I am using stm32 g071 and what I have done in the code is to toggle pin and send the value through adc and finally output through dac. Theoretically, the GPIO output and DAC output should be simultaneous but due to processing time and all, there will...

I am using STM32-G07RB and reading the sine signals passed from a LPF circuit. There is a delay between the signals directly from the circuit and when passed through the MCU (adc port) to dac for oscilloscope display. The adc is triggered by the time...

Hi, i am trying to call timer interrupt handler using registers and the following is my code, but the problem is that the function is being not called, I see no output in the oscilloscope or live expression. First my DAC value is still 0, the counter...

I am using HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) to generate a sine wave based on DDS and I have also implemented ADC to get the value and perform some calculation. My sampling rate is 100KHz so my timer interrupt should trigger ever...

Thanks for the suggestion. For now, somehow, I got the result. Hopefully, this won't change. I just changed the adc channel. @RhSilicon @GwenoleB Edit: Seems like it's reading the opposite way. Will try to update here if I fix the problem. 

Hmm okay. As i understand these three adcs can read values simulatenously.In my case, it's fine for me if the same adc with two different channels read values sequentially because I assume the HAL get value is fast enough that i can read two values w...

Hi Gwénolé,This is what I am doing right now. As I learnt that getvalue doesn't actually do anything more than accessing the registers, I am not sure where the conversion is taking place. void TIM2_IRQHandler(void){if (TIM2->SR & TIM_SR_UIF){HAL_GPI...

But it says, 16-channels like in DAC where it has 2 channels. I used two DAC channels successfully. It should be able to read sequentially inside the timer, I assume? Maybe my question was a bit misleading. But thanks for the video, i did check it ou...

Hi. How does one use this select channel, if you want to read adc values inside a timer interrupt? I have started the ADC in the main loop once, but starting and stopping inside the timer didn't work for me.
