Hi all,

I am using USART on the PIC18F at a baud rate of 9600 (Xtal 20MHz). Should I set BRGH to high speed or to low speed?

Thanks in advance.

Thanks for the reply. Since the PIC18F has a USB protocol, is there any advantages of using USART over USB?

USART RS232 is +-9v (generated by the MAX232 etc) or RS485 differential, the USB is 5v, with generally a higher BAUD rate but lower distance capability.
Max.
