Hi,guys! I really need help here!!!!
Anyone can give me a LPCexpresso 1769 sample code on RF communication (T5/R5)?
Really headache!!!!

I hope you have the 3.3V versions of hardware, otherwise you will need level shifters.
these are just serial devices, so a UART connection should work.
If you control both ends, then there are many open source protocols but the T5/R5 is uni-direction.
if not, then you have to implement the protocol and you didn't say what that might be.

Thank you for replying me!!
Actually want I want is just using T5 to give out instruction and R5 to receive them using UART.
At the transmitter side, I use simple membrane keypad as input and and different colours of LED as output.
So it' s like press "2" on the keypad, and the corresponding LED will light up.

I'm not very sure what library I need to include in my cold and what values do I need to put eg. Baud rate.....
Hope you can give me as ample code for my case!
Thank you once again!
