Hi all;
Iam doing a project and i was wondering if i can setup my stamp to communicate with IrDA enabled devices?
My goal is to have the stamp use a modem to log onto the internet, download a picture or data file and send it via infrared to·a PDA.
Iam looking at speeds of 115kbps.

Thanks for your help!

    I'm not sure IR buddy product can be used with the IrDA protocole, since the doc mention the RC-5 protocole...rolleyes.gif

    idea.gif So I typed IrDA in the Parallax search engine and I got a book which mentionned a commercial product called IrDA Communicator and seems to be sold per a swedish company.
    To code IR communications on a Windows Mobile device with the Compact Framework have a look here

    Bluetooth would be a better data link to the PDA, more bandwidth. Since IR is line of sight, you have to be in the same room or very close by. Palm has a cheapo version of 'C' for $18USD that can get you into creating a software applicaton.

    Stamps have a Bluetooth link now, but I am not sure if it is bi-directional or only passes data towards a computer.

    The EB500 is a complete 2 way bluetooth system. I haven't used it with a PDA, but it does great with a PC.

    1. IrDA is very limited in distance.
    2. The BS2 is very limited in memory capability. Downloading a picture file takes a LOT of ram.
    3. The IR-Buddy is more a TV Remote Control device replacement than it is a generic IR device.
    4. IrDA is basically RS-232, modulated on an IR driver. You'll need external hardware to implement this.

    Hi all;
    I bought the Stamp 2 Communication book and built the IrDA Communicator circuit. The main issue was actually the fact that it doesn't implement the IrDA protocol its a very simple transmit of RAW infrared. It doesn't do initiate discovery of a device communicate and do all the required stuff as if you want it to communicate with a laptop.

    The problem with the Sweedish company's Irda is that it is a bit slow.....i asked them they said the fastest is 57600bps, i looking for 115kbps.

    All i want to do is program a microcontroller to detect an IrDA enabled device. Have three buttons (one for picture, one for schedule, one for map) and then have that file sent via infrared. If that works i will then take it a step further and have it log on to the internet and transmit real-time data like news.

    i greatly appreciate your help!
