'Need I2C EEPROM Programmer Recommendations (~$100)'

I need to buy a programmer to burn I2C EEPROMS which will be used as
ROMS. These I2C devices will interface to a PIC16C74 and contain lookup
tables and LCD Text Messages. I would like to find a programmer with the
following features:

* Costs around $100 or less
* Preferably works off a serial port and doesn't require a daughter
card that needs to be installed in a PC (portability).
* Has a software interface that would allow me to enter ASCII
data, which will be helpfull for my LCD application.
* Preferably a Windows software evironment. Many programmers come with
crude DOS software that doesn't work well under the DOS Shells of
Windows NT/95/98.

Please provide manufacturer, source, price, comments etc.
Thanks!

Couldnt you just make one? have a PIC recieve the serial data from the
computer(using MAX232 or the like) then have the PIC talk to the I2C bus.

Warp-3 $89AUD  (USD$57 approx)

Warp-3 = RS232

Warp-3 "DEE" ASCII file, direct edit, MPASM compile.

Don't have windows support for the SEEPROMs but my DOS software now runs
well under windows.

As a "bonus" feature, you also get a programmer that can program all the
PIC12,,14, 16 family.

Its great and bound to get greater. Please follow the URL below.

Thanks.

i2c devices (including eeproms) can be interfaces in almost any way you
like:
directly from a PC serial or parallel port, or with a PIC (or another uC)
inbetween.
Search the web for do-it-yourself designs...
Most compilers come with libraries for both asych and i2c interfacing, so
programming a PIC to do what you wat is no big deal.

Wouter.

 It should be far easier than that.  I'm sure someone else has
mentioned it and I've forgotten the web reference, (Ahh!  Here it is:
http://www.student.dtu.dk/~c888600/newpic.htm ) but you don't need a
PIC, you need a connector to the serial or parallel port, a socket
for the IÓC chip and a handful of cheap components.

 It will work under DOS, it will work under Windoze 3.1 or 94, but - it
won't work under NT.  Very little will, so there isn't much point
fussing about it.

Hi,
I have such project. It is ready and I use it. It is a small experimental
panel having a 8-pin socket for I2C eeprom, a 16F84, a 4MHz resonator, a
7805 and a 9-pin RS232 connector. I have a firmware and a PC-side software
- of course it all runs under DOS. No Windows. Nope. Never.  If
interested, send me a private e-mail.

Hi,
here is the runtime package. The numbers on the left side on the schematic
refer to a 9-pin FEMALE Canon socket. Given connections are to be wired
1:1 to the PC.

The software is self-explanatory. Here is a short checklist how to do all
the stuff:

1. Build the circuit on the breadboard or whatewer.
  (The ceramic resonator can be replaced with xtal & 22 pF capacitors).
2. Program the PIC16F84-04/P using 24b4pgrm.obj & plug in.
3. Connect the circuit to the PC.
4. Start the 24pgmr.com giving it the com port (e. g. COM1).
5. Enjoy!

Remarks:
- I believe 24C64 can be programmed as a 24LC65
- the help of the hex editor is callable with F1.

Background informations:
- the communication setting is 4800,n,8,1 (set automatically)
- only changed EEPROM cells are re-programmed to enhance the endurance
- data communication is protected with checksums & ACKs so a lower quality
 should not lead to mis-programming only speed loss.
- data are transferred in 8-byte chunks.

A modest voluntary one-time donation is kindly appreciated, but not
required.
Comments/suggestions are also welcome.

I tested and use the system every day, but NO WARRANTY etc. etc.
