#86209 - P1 serial data |
Hello there, i am trying to intereface an AM-TX module to the 8051 uC. I am using the uC to transmit an id to the AM module port one, this is used due to the logic levels. Is it possible to use transmit serial data over one bit of port one.
I understand that P1 can be used for parallel data but i want to use just P1.1 or P1.2 etc for serial transmission. Is it possible to use PCON ? Many Thanks S Harris |
