I have the Nucleo-H743ZI2 board. It uses the STM32-H743ZI part which has a reasonably fast 16-bit ADC, or at least that’s how it is specified: https://www.st.com/en/microcontrollers-microprocessors/stm32h743zi.html3× ADCs with 16-bit max. resolution ...

I am trying to run a simple ADC example provided by STM32CubeIDE for my Nucleo-H743ZI2 board. I know the basic functionality of the board hardware and computer connection is OK, because I was able to write a simple program to blink all three user LE...

Thank you, that is good to know about L1. We are not using the ethernet port at all. I've got my soldering iron warming up now.EDIT: you were absolutely right. Removing L1 reduced the Nucleo-H743ZI2 board current draw from USB power at 5.14V from 155...

FWIW I managed to get some code working by modifying a project I had previously from a different board. Still feels odd that ST has example code for the obsolete H743ZI board, but not the current H743ZI2 which is not exactly brand new, given it came...

Further reading indicates there are differences between the H743ZI and the H743ZI2, the boards are apparently not compatible, including in the ADC section definitions. So there should be a separate, different example for the ZI2 board, but there is n...

I might add, the call to HAL_ADCEx_Calibration_Start() takes about 66 seconds after start before returning with a value 1 and while I'm not sure how long is normal, this length of time seems excessive. I have now tried this on two different Nucleo-H...

Update: using a different browser, different login and different computer (Linux) I did get the download to start. So this could be some new company IT rule preventing downloads to my work laptop.

Nucleo board using STM32-H743ZI ADC seems noisy. Is there any way to improve?

Nucelo-H7432ZI2 basic ADC example fails in HAL_ADCEx_Calibration_Start()
