    Re: Infra Red Remote control project

    well most of the remotes used today follow RC5 coding, a type of manchester code.Connect an IR receiver TSOP 1738 with its associated circuitry mentioned in its datasheet to one of the external interrupts of 89C51RD2. i don't know of any C program but assembly language decoding program is available on the internet.

    Using an external interrupt plus 1timer, you can decode it by start and stop and read timer data inside an external interrupt routine.
