I'm using an STM32F407, I want to use the falling edge of a PWM to trigger the ADC and then with the DMA move the data into a variable. The problem I have is that I am trying to check if the ADC is actually taking samples at the PWM frequency. I am t...

Hi, I need to sample a signal at a frequency of 10kHz. To avoid the use of the microprocessor I thought of doing it using a 10kHz Timer that triggers the ADC conversion on its falling edge, in addition, I need the ADC read value to be transferred via...

Hi, I am using a STM32F407. I programmed one channel of ADC1 to start on the falling edge of TIM8, which has a frequency of 100 kHz. So far so good, the ADC performs a conversion every 10 us (100kHz), measured with the HAL_ADC_ConvCpltCallback functi...

Hi!!I am using a STM32F4 Discovery board. I am using the ADC1 and ADC2, both with DMA. I need the conditional to know which ADC was the one that finished reading data. I tried if(hadc->Instance == ADC1) but it only works when DMA is not used.Could yo...
