NECLEO-H753ZI CUBEMX Pinout View PD8/PD9/PB0 pins in RED

[RongShengWang]

Hi,

    I do not use PD8/PD9/PB0 pins in my design. Therefore I did not configure them in CubeMax.

    Why NECLEO-H753ZI CUBEMX Pinout View PD8/PD9/PB0 pins are in RED? 

Thanks,

 

Peter

Hello,

All these pins are colored in red because you started your project from the board and you selected at the beginning to intialize the BSP:

You've clicked OK:

So you get:

To disable these IOs, go to Bsp tab and uncheck all these checkboxes.

 

Hope that answres your question

Hi,

    Are those pins used for USB-Serial Debug purpose?

    If so, I can't disable them.

    Can I just leave them in Red and generate the code? Any trouble?

    Thanks,

Rong

Hello,

Are you the original OP?

If yes please use one profile.

If you are talking about VCP pins, the answer is No. These are for the virtual comport not for debug.

 "These pins ( PD8/PD9) are reserved for the virtual comport " - I have to leave them unchanged. Hopefully the compiler will keep the reserved function without any change. This is what I mean.

The compiler doesn't make any change on the generated code, otherwise the option you selected in CubeMx doesn't make sense any more ..
