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

A surplus store in our city is selling the "Jeteye PC" device for $1.

It appears to be a rs232 IR sender/receiver in a cute small package. I cracked it open and found 3 SMD chips, a crystal and a 2 bulb IR device (plus a few caps and transistors).

I looked up the chips with an online data *** service. One of the chips is a 8 pin low dropout regulator.

The other 2 have me stumped:
(1) 7001   90B823
(2) TI 84D13RK  LV00

Ideally I would figure out where to tap the TTL levels so I could directly attach it to a PIC.

Has anyone played with these things? 

Not I. But "7001" rang a bell from 20+ years ago.

Tried a couple of Google searches.

HSDL-7001 · IR 3/16 Encode/ Decode IC with 16X Clock Generator
which stated

The HSDL-7001 modulates and demodules electrical pulses from IrDA-compliant transceivers. It can be used with a microcontroller/microprocessor that has a serial communication interface (UART).
The HSDL-7001 can be placed into the Internal Clock Mode or External Clock Mode. An external crystal is needed for the Internal Clock Mode. In applications where the external 16XCLK signal is provided, a crystal is not needed.
There are two data transmission modes. Data can be transmitted and received in either a standard 3/16 modulation mode or a 1.63ms pulse mode.

Might this be relevant?

[ no luck searching TI 84D13RK ]
