Hai everybody,

I'm doing a project on wireless communication,
I need to transmit data from the serial port of my system to the PIC 16F877 Microcontroller or to a serial port of another system

Please anybody provide me with the perfect working diagram and circuit diagrams that are needed to transmit data and receive that data.If U have used Max 232 then send me its circuit dig also.

I've planned to use a 433.92 MHz transmitter and receiver.

I've to transmit say 'A' from one serial port to another wirelessly.

Thanking you,

Waiting for all your reply's,
