Hi!

I'm using Nucleo-f429zi board and my trying to configure it to read and write data over modbus RTU (RS485)

and i'm using keil uvision 5 to program. I have referred some videos and post on how to configure STM32 and its USART port for modbus communication but when I try to configure RCC in STM32cubeMX i get a error highlighting

master clock 1 and when i hover mouse courser over it, it says conflict with usb.

can someone explain me how to solve this error and why i'm facing this issue?

Is the Master clock output (MCO) output needed for the project? If not, ignore this and keep going. It is not a real conflict.
