Resolved! STm32G431: Advice on how to continuously scan (regular) ADC input channels and place results in memory?

I assume I would use DMA and have gone some way to (unsuccessfully) sample values in 4 channels in ADC1 and 3 channels in ADC2. However all the sample values seem unchanging for each ADC and obviously don't contain data for all the channels.I can't f...

STMh734 GPIO as parallel bits interface

HiI would like to use the GPIOs on the STMh743 as a parallel bit bus for A2D sampling through an external A2D device. The sampling resolution could be low as 4bits thus 4 pins could be used for data. The sampling rate should be 100Mhz so it will take...
