Hello, I´m trying to connect my 8051 to another 8051 with P3.0 and P3.1 using UART, but I can´t, I dont know why?.....The way that I do is:
*Start UART in both Systems *Send data to the first 8051 (TXD-P3.1) *Receive data in the second 8051 (RXD-P3.0), Then I will send it to the P1 to view it on display
Help Please!!!!!!!!!!!
