Voltage reference buffer output does not match expected value?
Device: STM32G061 (custom board), system running at 8mhz.I set the vrefbuf mode to Internal voltage reference mode in cubemx. According Scale 0 the expected output on Vref pin should be 2.048V but the value i measured was always 0.2-0.3V greater than...
Resolved! STM32H743 ADC/DMA apparently skipping samples
I have a set up where I'm reading from ADC1 via DMA1 S0 into a circular buffer in RAM2. The problem is that it is randomly skipping samples. I initialise the buffer to a known bad value so I can see that some addresses in the buffer are not being ove...
