Hi,
I been trying to use a BSII and or a SX28 to implement IRDA using the 2120 IR encoder ic. I got the circuit done but I must be doing something wrong. My question is has anyone ever used a USB to IRDA dongle (I bought one for $8) attached to a pc and a microcontroller to implement IRDA. Any other info on IRDA would help also. Thanks, Curtis

Luck is with you my friend, there is a really somple method for using a Stamp with IRDA. Here is the simplistic hardware layout:

Any PBASIC BS-2xx Stamp module (or SX) ==> MAX-3100 ==> I/R TX/RX ==> IRDA!

You use the SHIFTIN/SHIFTOUT commands on the SPI/Microwire type interface. One real nice feature is that data buffering IS INCLUDED! Here is a web page which has the basics of how to work with the MAX-3100 and IRDA (thanks go to Dr. Tracy Allen):

Here is the data sheet for the MAX-3100:

Good luck, and let us know how you make out with it.

Thanks Bruce, I printed the information and I will order the MAX-3100 and try it., Curtis

I'm SURE they'll be happy to send you a free sample, if samples are available.
