hi sir,

thanks for your reply. my problem is unable to identify the key pressed in receiver side(in microcontroller). i thing this is not sufficient to identify the key at microcontroller. i like to know output details of the remote like waveform (time vs data). after that only i can able to identify difference between the keys. please help in this issue sir.
