MCU: STM32G474 (100 pins)PIN: PD12 configured as ADC input with 12-bit resolutionPIN: PE1 configured as GPIO_Input to trigger software reset thru NVIC_SystemReset()How to duplicate:1.) Inject voltage on PD12 and monitor the ADC raw reading.2.) Trigge...

Been using ADC channels: ADC1, ADC2 and ADC3Upon checking the other ADC channels being used, found out that the whole ADC3 channel was affected.The code is being built on a lower version of STM32Cube (1.5.1) and the delay being used was 10us.When com...

Just want to share that by injecting an additional delay in the initialization of the ADC, the error improved. The ADC init sequence becomes:(1) Initialize(2) >20us Delay (manually added)(3) Calibrate(4) Enable(5) Convertand it seems related to the A...

Hi JW,Thanks for the info.The ADC is configured as follows:(1) Initialize(2) Calibrate(3) Enable(4) ConvertThis configuration is also within the main() function.The triggering and conversion are done considering what's written on the errata (ES0430)....
