RS232 to IrDA

[Dingus]

Hi,

I have a piece of equipment that spews out serial data. I need to capture
this data with a PDA's IrDA port. Half duplex only, machine to PDA.

Has anyone got info/circuit details preferably using a PIC, and hopefully
the software in PIC assembley code ?

The commercially available stuff is all too over the top, and pricey, and
besides I want to construct it so that it fits snuggley onto the PDA.

Thanks kind folks, hope you can assist!

Look at the Microchip IrDA stuff.

We played with the MCP2120 and the MCP2150.
If memory serves, it was pretty easy to get the 2150 to just to a serial
to IrDA link.
