			       Overview

This README file is part of the document package for version 1000-2 of
the IR-suck IR tag reader board design.  The IR-suck tag reader is
intended to receive and decode data from Squirt2 tags and provide that
data over the MIThril i2c bus.

The microcontroller software for this device is available from the
MIThril web CVS repository at the following URL:

http://borglab.media.mit.edu/cgi-bin/cvsweb/pic_code/ir-MITh1.c

Software (in the form of C code intended to run on the BSEV core) for
reading this device can be found in the enchant_apps CVS module.  The
relevant files are tag_reader2.c and tag_reader2.h (NOTE: this code
will not work in isolation -- you will need to download and build the
enchant_ipc module in order to run tag_reader2, and you will probably
want to use the tag classifier code found in the tag_class module as
well)

All of this software can be found through the MIThril web CVS
repository:

http://borglab.media.mit.edu/cgi-bin/cvsweb/enchant_ipc/
http://borglab.media.mit.edu/cgi-bin/cvsweb/enchant_apps/
http://borglab.media.mit.edu/cgi-bin/cvsweb/tag_class/

			    Release Notes

Version 1000-2 notes:

This is the "old" version of this hardware -- I was hoping to put out
an updated design that matches the circuit on our multi-sensor board,
but haven't had a chance.  

Version 1000-2 bugs:

!!! IMPORTANT:
!!!
!!! The header for the tag detector cable is not keyed, and plugging in
!!! backwards will cause the detectors to smoke. 

The design for the detector cable is not specified in this document
package.  Hopefully this will be fixed shortly.

The PIC intended to be used on this version is UV erasable, and the
board does not support in-circuit programming. 

There are minor flaws in the silk screen layer -- we haven't
fabricated any of these boards with silk screen yet.
