How can I use a serial port on the arduino connectors?

[Maximiliano]

I have a stm32H745I-Disco and I would like to use some UART and I would need it to be through one of the pins that the board has called arduino connectors.

I was able to use the USART1 without problem but now I want to use it together with the display and I realize that the pins PB6 and PB7 are being used by vsync_freq and render_time.

What can I do?

The schematic is : https://www.st.com/resource/en/schematic_pack/mb1381-h750xb-b01-schematic.pdf

Doesn't PB6/PB7 clash with the CAMERA (DCMI) not the DISPLAY

Hello Tesla DeLorean

STM32Cubeide indicates the following:

and if I am not mistaken in PB6 named B5 in the schematic it says that it is connected to a pin of the LCD.

Show me this on the MB1381-B schematic for the H745I / H750I DISCO board..

Not associated with SCREEN/DISPLAY, only DCMI

LCD_VSYNC is PI9

Are you sure you're using the right board template?

@STTwo-32 This schematic is unhelpful, the ARD_D0/ARD_D1 connect to PB7 / PB6 USART1 / LPUART1

Show more of you screen so we can understand the CONTEXT CubeIDE is working with, that the board and the part selection are internally consistent.

ST could have messed things up, but this is for DCMI, and the H750B-DK (w/STM32H750XB) doesn't have a camera interface connection.
