By the way, I didn't touch it because I was unsure if there was a good reason, but why is continuous conversion mode used if we stop the ADC after receiving the first conversion? Wouldn't it be simpler to just use single conversion mode? |

This moves the ADC and channel configuration code to a new public function
prepare_read, then adds aread_without_preparingfunction which just starts a DMA transfer and starts conversion. This reduces wasted time reconfiguring the same channels repeatedly.Tested on my STM32WB55RG
