gTAG: USB to JTAG interface
============================

This is the README file for the schematic of gTAG.

Short description
-----------------
gTAG is an interface to connect your USB port of computer to talk
to your circuits which talks JTAG.

Copyright
---------
These schematics is (C) by Stefan Petersen (spe@stacken.kth.se) and
released under GPL (see the attached file COPYING). GPL is mainly
written for software, ie intellectual property in electronic form.
By making this schematic an intellectual property in electronic
form gTAG schematics can be covered by GPL.

How?
----
These schematics are made with gschem and netlists are then generated
with gnetlist. Both gschem and gnetlist are part of gEDA
(http://www.geda-project.org/).

Files
-----
The distribution of the schematics of gTAG should consist of:
* README - this file.
* crdist.sh - shell script used to generate the tar.gz.
* Four component symbols:
  - 7414-1.sym - Original 7414 from gschem without power attributes.
  - max882.sym - 5-to-3.3 V converter.
  - cy7c64603-52nc.sym - USB microcontroller from Cypress.
  - sn75240pw.sym - Surge supressor for USB
  - copyleft.sym - Symbol with GPL text for all schematics.
* Five schematics with four symbols:
  - gTAG.sch - Toplevel schematic for gTAG
  - gTAG-jtagio.[sym/sch]
  - gTAG-ucont.[sym/sch]
  - gTAG-consio.[sym/sch]
  - gTAG-psu.[sym/sch]
* gEDA rc-files for this project:
  - lepton.conf - Netlister settings.
  - gafrc     - Symbols and subschematics search paths.
