As adcresults is of length 4, this would be the correct length. That said a higher buffer size decreases your CPU load, as it can process several samples at once.Both callbacks are always called and I would use them both to avoid data corruption by...
In an old project for an STM32L4 in stm32h7xx_hal_adc.c it states:"@param Length Length of data to be transferred from ADC peripheral to memory (in bytes)"I remember that was an issue in that project, too.In a fresh STM32H7 project the same line is:"...
Similar here. I tried it on two different laptops for the NUCLEO-H743ZI.A short test on a ubuntu machine revealed no problems.On the other machine running macOS High Sierra the user interface for the clock configuration seems broken.When I click one ...
