Previously through testing using fast channal, single-ended input can realize less than 1.5M sinusoidal FFT, I want to add RC filter on the input, but I don't know what is the limitation for RC selection? Please help me, the cutoff frequency of the r...

I want to use STM32H7 SPI to drive DAC chip to generate sinusoidal wave. Can you recommend me relevant routines or ideas

I would like to use the ADC3 of the STM32H7 series chip to realize that the voltage is collected once, and then the voltage is collected at a different point (meaning is it necessary to use two channels, because I see several channel choices in there...
