We use a PIT and DMA to scan a number of ADC channels ever ms on a KV31. The ADC clock is 10 Mhz (MCU clock divided by 8). On occasion, post a reboot, the single ended temperature reading from ADC0 will be stuck at 25 C or on rare occasion report roughly 10 C below the actual measured temperature. All other voltages on that ADC appear to be normal.
Has anyone had an issue like this?
