Resolved! What voltage should be clamped on for analog input, vref or VDDA? At what condition positive injected current happen when the pin is used as analog input?

Hi, I'm using STM32H7A3, and I’m a bit confused about injected current for pins used as analog input. In our design, I used both 5V tolerant and 3V tolerant pins as analog input. And VDD=3.3V, VDDA is connected to VDD with a bead. And Vref is 3V. And...

ADC gives clumped values that result in a poor waveform.

hadc4.Instance = ADC4; hadc4.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV4; hadc4.Init.Resolution = ADC_RESOLUTION_12B; hadc4.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc4.Init.GainCompensation = 0; hadc4.Init.ScanConvMode = ADC_SCAN_DISABLE; ...

MEM TO MEM DMA

I am using STM32H743ZI2. I am using 6 ADC with external timer and dma to acquire data. After I acquire adc data (16bits), I will use scale ratio to obtain physicals value I would like to get. This value will be 32bits. After I do power (a x a), the r...
