Hello, I am trying to do an injection conversion of the DFSDM peripheral with the read process being triggered via an internal timer (TIM1) utilising the HAL drivers. Specifically, I want to set the counter to count up and trigger the read process ev...

Hello, I am working with the low level drivers and trying to configure an ADC to read 2 channels via the Cube IDE. I am triggering the read of the ADC via a 1 ms internal timer interrupt. Note I am trying to do this read via polling and not via inter...

Hello, I am trying to interface to an external ADC via SPI. I amusing the STM32Cube IDE with a Nucleo-144 STM32L552. The issue I am having is that the ADC requires an unusual number of clock pulses (18 as per data sheet - see attached screenshot). No...

Thank you for your response. Yes, I think you are correct. You would have to directly set and clear the ADC registers if you were to approach it this way. However, I found doing it via an injection conversion worked for me as I only needed to read fr...

Thanks for the replies. I managed to solve the problem, and as you suggested, I used the 8 bit mode to write 3 byte frames worth of clock pulses. It was then just a case of parsing the desired 16 bits together. initially i was having difficulties as ...
