Suppose you want to get the max sample rate out of the ADC and you can not use DMA, how would you do that?

I need to have ADC1 and ADC2 run sumultaneously. Each ADC has 2 injected channels. I want to start the ADC once and then have it constantly run converting the 4 injected channels, putting the result in the 4 associated JDR registers and raising a fla...

Hi,When I add variables to watch during debugging, the watch window does not display the actual value of the variable. I know the variables have the correct value because the program flow based on the value of the variable is correct. The watch just ...

Hi,I am working with the Nucleo-H743zi. I am unable to get the DMA working in dual simultaneous mode. I see the ADC12_Common CDR registers are showing the ADC values properly, but my DMA never seems to fire.I can not find an example of ADC dual simul...

I think part of the issue is that the HAL ADC ISR is too heavy. I will trim the ISR code and just set registers directly and see if that improves things. In my ADC ISR, I set a flag to indicate that new data is available. is there a way to do that wi...

I have DMA channels free, but I have to transfer 16 ADC samples or more at once using DMA or else the CPU is constantly servicing the DMA and ADC interrupt leaving no left over CPU cycles for my application. 16 sample latency is too high for my appli...

Turning off the cache was the panacea. Thank you.I had almost given up on the H7, was going to admit defeat and to go back to using a M4 class uC.
