Re: Anyone ever use a Jeteye IR with a PIC?

That was a great find!

I was searching for the 2nd number thinking the 7001 was a 'house' number.

The last page of the PDF has an application note that shows how to hook it
up to a microcontroller.
I'll give it a try, it even looks good for on top of a BOT.

I bought a few of them, I hope to use one as a remote PC connection to a
hamradio that uses TTL serial for CAT control (instead of the standard
max232 or ds275 solutions).
