i'm trying to learn about ST USB LIBRARY AND CLASSES . i tried to run an example on my stm32h7a3ZI-Q board but i didn't succeed . i tried the HID class to make the board act like a mouse . i really copied the MOOC tutorial video step by step and the code was compiled with 0 error but when i run it ,nothing happen when i press the blue button( i checked it in an other led blinking project and the button is working fine) . so i tried the keyboard tutorial from the mooc tutorial also but the serial monitor didnt show anything . i checked the internet and it appears the board lacks a VCP so i tried to run a project with the CDC class to simulate a VCP to link the board with the serial monitor but also it didn't show anything despite code was clean from any error and im pretty sure i used the right functions(CDC_TRANSMIT_HS) . i used CN1 if this helps . so is there any guide? . i really didnt now where i went wrong . i didn't find any article that guides me to run a project step by step like (webcam on h747i for example) i also tried the USB _standalone project .in the readme they said i only need to plug the board and run the project but when i did nothing happend . the cursor didnt move when i clicked the blue button.
here is the video i followed : https://youtu.be/6MJJwDKsKsc?si=t5FA9LdYFcq1V_7C
