eeprom reader software

Hi, I used IC-prog regualrly, and I needed to read/prgram an eeprom recently. The 'JDM eeprom' circuit (addon to the JDM programmer) didn't work for me. So I used 'Ponyprog' and the 'Easy I2C interface'. if your eeprom has I2C.

Here's the URL:



It worked first time.

I think its also supports microwire eeprom types, but I haven't tried it.

i2c eeprom reader

Is this the one you used? No other hardware needed?

jdm eeprom

BR, that ponyprog circuit was what I used, no other hardware, very simple. But thats for an I2C chip. Not SPI/microwire. perhaps if you told us what EEPROM you are using?? And remeber, this is with ponyprog software, not IC-prog. But they're pretty similar. Took about 3 minutes to DL the software, build the circuit, and program the chip :D

eprom reader software

I just finished it and it works for the first time!! Great!!
But I wonder whats the function of JP1 in the schematic? Should I connect it to ground or pull it up to +5V?
BTW I'm using it to program 24Cxx I2C chips..Any idea how can I modify it to support SPI/Microwire?
BR..

eprom reader

kasamiko, good to hear that!! It worked a treat for me too, these people who write programs like 'ponyprog' and 'IC-prog' are very clever people (and its all free!)

I believe the Jumper (JP1) is a 'write protect' test. Pin 7 of the 24cxx series eeproms is hardwired to ground to prevent its contents being over-written, so I guess the jumper is there to test this. To write to the chip, pin 7 must be pulled up.

The SPI/Microwire interface is on the ponyprog website, theres a link for it about half-way down, but here's the URL :)

https://www.lancos.com/siprogsch.html

This is a base board, to which various 'dongles' can be attached to program different devices. At first glance, it seems you won't need the 'external power' part (in a box in the schem) because SPI/micro doesn't need any VP voltage higher than the supply (5v). So, you'll need the 'basic' base board, and the connections for SPI/uW are shown lower down.

I haven't tried this, but I'm going to build it anyway, got so many bits'n'bobs laying around, those components need to be doing something useful :D

Good luck.

BuriedCode. (stuck in the 80's)

build eeprom reader

One thing I used this programmer is that it connected via LPT port since my laptop has no serial..
That baseboard will be useless for me since it was designed for serial port..
A modification for the I2C programmer to work with microwire is what I need..
Thanks anyway..
