GE-Flash USB Programmer
A USB Capable Programmer for the X2212 EEPROM and GE-Flash
Software
The pictures
below show the first USB programmer prototype. Currently
this is the only programmer prototype I've built and it
is being used for the software and driver development
purposes. The USB programmer is based on the Atmel AT90USB128
chip and will require development of a native Windows
7 bulk mode driver (user mode).
The microcontroller I/O lines are tied directly the programmer
socket pins for the X2212 interface. The SPI serial interface
pins are tied the lower portion of the socket and support
the X2444 in native SPI mode. Thus, the microcontroller
is directly interfaced to the EPROM in a typical application
configuration and provides extra reliable programming
and verification operations to EPROM's.
Development is still in progress as time permits and
I have no further information or target pricing available
yet. Further information and developments will be posted
here as things progress.

Currently software development is on hold due to
work and family obligations, hopefully I'll be able
to resume work on this project at some point later
this year. I have managed to get some of the basic
firmware programming logic working however.
The prototype GE-Flash-USB unit will now program
EPROM's using the optional RS-232 interface. The
RS-232 interface can be used to emulate VX2212 programming
mode and will allow the unit to support RS-232 or
USB communications mode programming.
Stay tuned...
