Hello All, and Clive,
I've went back into the guts of my program after a long time being out of it, and I dont know how I can know the actual clock speed of my unit. I dont have a scope that does more tha...

I finally got ADC to work, so I went overboard and enabled 6 adc channels plus the temp, vref and vbat all on ADC1. Problem is when its running my data coming out of dcmi seems to get garbled.
I know its...

I refactored my interrupt based circular buffer into a dma RX stream coming from the USART2.
I frequently read how many bytes the dma stream has read and then reset it back to zero. For example.

Hello Yora,
It's nearly impossible to help you without seeing your code, specifically the initialization of the vector table and your usart init code. The best thing we can do is point you to example code wh...

Yes Clive your exactly right (as usual). The errata states
2.1.10 DMA2 data corruption when managing AHB and APB peripherals in a
concurrent way

I went down this path, it seems to be almost working. Just the tmp/vbat/vref dont seem right. I'll look for errata.
void ADC_IRQHandler(void){
static int i;
if(ADC_GetITStatus(ADC1, ADC_IT_EOC))
{...
