#100209 - Serial RF with AT89C51 to AT89C51
Hi

I have recently bought TLP-434 and RLP-434 and I decided to experiment with it. So I wanted to implement directional serial data transmission from AT89C51 to AT8951 and my code from TX basically use the UART in order to transmit a data to the receiver where it use UART to capture the 8 bits. My both uC implement 2400 Baud.

There are two buttons in my transmitter circuit and I expected that red LED switch if I pressed the first button. The second button allows my blue LED switch on. Unfortunately the RF link was not very stable as LED didn't switch on straight away after pressing one of the button. Sometime the LED switched on without me pressing the button.

I have been informed that if I use bit-banging at the receiver instead of UART, would solve the problem. I don't know it is true or not.

Btw do you have serial bit-banging for the receiver in C? I would be very very grateful if you provide me the C asap because I have been struck with my project for nearly two weeks :-(
