:roll: HI All

I am trying to make a digital data transmitter and receiver. I am thinking whether to go with ASK or DTMF..... Can any guys here help me in this regard... Please read the following to understand my project better.


I have two bytes of data that need to be transfered from Unit 1 to Unit 2. The unit 2 may reply back with 1 byte of data to Unit 1.


That means the first byte is bi-directional and the second one only flows from Unit 1 to 2.

Guys, please help me do this...

Thank You a lot. (IF you need further clarification on the project, please send an IM on my yahoo Messenger (johnmmbae)).

Thank You In Advance.

John
