I'm a student and i'm creating a project of a HMI adc acquisition interface with a STM32H757I_EVAL according to this video: https://www.youtube.com/watch?v=Y7d6-59YQu8
I created the HMI as simple as possible, simulated and uploaded into the board via TouchGFX and works fine. Then i wrote the code according to the video with my teacher into STM32CubeIDE, compiled and got 0 errors and 0 warnings. Simulated again into TouchGFX and still simulated fine.
When i upload the code into the board via STM32CubeIDE it upload but the lcd monitor shows a pixelated grey screen, but if i touch the button i placed into the HMI it changes screen into a different pixelated grey scale screen, so the "button object" works but not displayed properly.
When i upload the code via TouchGFX it compiles but when flashing it got "undefined reference" error to the hal adc instruction i wrote (start, pollforconversion, getvalue,stop) and the flashing fails. I got this exact errors:
