> >What's the chip number, and where do I get it? Microchip has an app note on doing this. I don't recall which chip they used, but I'm sure a search will pop it up. Ubicomm also has this as a reference design, with freely available source. That takes an SX28 at 50 MHz, and their code. You can use any of the available IRDA transcievers, Agilent and Zilog both make compatible units. However, you can't just tag the transcievers onto a serial line. You need a micro to manage the link. Watch the transciever power, they draw large pulses of current, and have poor rejection of power supply noise. Bypassing is critical, PCB layout is important. ************************************************************** http://libretto.basiclink.com - Libretto mailing list http://libretto.basiclink.com/archive - Archives http://www.picante.com/~gtaylor/portable/faq.html - FAQ -------TO UNSUBSCRIBE------- Reply to any of the list messages.
