hi guys
how will interfacing irda communication

Re: irda

Hi

From the hardware point of view you need a IRDA transciever from for.ex. Avago, Vishay etc.
If your serial port isnt IRDA compatibel i.e. 3/16 encode/decode you can use a interface chip like Avago HSDL-7002 or Vishay TOIM4243

You can find much information at www.irda.org

hi jzo777n
thanks for reply
can you give circuit diagram for MCP2155(IRDA Encoder/decoder) interfaced with at89s51.

I can provide you with a circuit diagram for the MAX3131(IrDA Encoder/Decoder).

If you want it, just ask.[/b]

Re: irda

You can just use a modified version of a software UART to do the same job, but instead it toggles the TRIS of a hardware PWM pin on a micro controller...


Depending on the receiver, upto 1200 baud is no real issue. Not sure what the TRIS is referred too on an AVR, but for a PIC it’s the input/output control of a pin

microchip provides many application notes, u can search in microchip site
