interfacing RF wireless modules to ATMEGA16 microcontroller

[D.V.G. Krishna]

how to interface RFmodeles to atmega16 microcontroller. i heard that we cannot connet them directly with out  HT12E & HT12D and it need a saparate code

any idea of code ?????????

Hi 

It is not necessary to use HT12E/D in order to interface RF moduels with AVR microcontrollers. These MCUs support USART communication which means that you can directly connect Atmega's RX & TX to RF modules TX & RX respectively.

This doesn't need a separate code; regular USART functions can be used to transfer data wirelessly through RF moudles.

if you are talking about 434 MHz ASK RF modules then you are correct

you need HT12E and HT12D chips because they are RF encoder-decoder chips

how ever you can eliminate use of them by writing program for wireless RF protocol to send and receive data

arduino can help you here because it has virtualwire library
