Dear all,
My design is working.There was something wrong with 3.3V supply. But there is another problem now.
Pic18F1320 on transmitter board gives some data to xbee transmitter.It then sends data to xbee receiver.Value is received correctly by xbee receiver on receiver board.I can check it on hyper terminal.Now I want to do calculations on this data via another 18F1320 on receiver board.
The problem is for some strange reason 18F1320 pulls the voltage level down of serial data to almost 1.3V. A soon as I remove controller from circuit or reset it permanently the voltage level of serial data goes up to correct 3.3V. I have changed the controller & related circuitry as well as breadboard but to no avail?
D0 of Xbee is connected to RX of 18F1320.
any suggestions.
