Two different of those same chip were tested However Using another 93c56 from another manufacturer eepro no similar error. Discussion in ‘ Embedded Systems and Microcontrollers ‘ started by cdsJan 10, This is what it looks like when using the clip: Is this something the arduino can handle?
93C56 – x8(2k) Serial CMOS EEPROM Technical Data
There must be a procedure to clone the new cluster from the old. Writing to the eeprom isn’t too hard if you have access to the pins. I just figured why not try with my arduino and learn a thing or two. However when I use the test clipit is giving reprom read errors on every other bit.
But not that easy. Nov 5, 19 0. But what is the format of the data?
Everything runs on smoke, let the smoke out, it stops running Not to mention so many people in the jeep community have arduinos and would benefit from this. When using the 93d56 adapter in the zif socket it works perfectly. Embedded Systems and Microcontrollers.
Jan 10, 1. Why is using a battery causing my ATtiny85 to malfunction?
Well the good news is its a late model and I have everything I need from a junkyard for very cheap. Jan 11, 3.
Why is so8 test clip causing read errors with 93C56 eeprom (TL866 programmer)?
I have also tried 8dip versions of this eeprom in this same programmer and they never give errors so I must assume it is the clip.
Your name or email address: I just wonder if moving the chip might be a solution. Just as the title states I wish to flash a 93c56 EEPROM in my jeep cherokee gauge cluster because my old gauge cluster has malfunctioned and the new one will have incorrect millage on the odometer. Posted by nimaid in forum: This is what it should look like: Use this tutorial to get your FPGA development environment setup and understand the tool set and basic development process.
Given that it’s ‘in-circuit’- I presume soldered – you’ll probably need to break the leads to CS, SK ,DI DO, so as to prevent the existing curcuitry from preventing your operations. I’ll see if I can find my old bitbasher – but given the datasheet you could figure it out. The reviews for this clip dont mention this problem, and it is sold by the same company that sells the programmer.

The errors are consistent and seem to happen with every bit value except FFFF. No clue how do I go about getting this info? I actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher. My best guess is a flaky connection on one of seprom wire to pin connections at the back end of the clip. And here are a few other bit values, spliced together to save space In every case except FFFFthe even numbered bits 0,2,4, I would still like to know why it is able to write but not read?
Why is so8 test clip causing read errors with 93C56 eeprom TL programmer?

Yes, my password is: I know this guy here did it with an off the shelf programmer, which is quite expensive compared to the arduino I all ready own. And if so how would I go about doing this? If you had the appropriate sw from the manufacturer I bet you could 9c356 this via the OBDII connector – but I also bet they’re not telling you how! TomGeorge Design and Repair of industrial control systems. It won’t be easy, as they don’t want crooks ‘clocking’ the mileage. Is there a connector next to this chip which does this?
I’ll look into that cloning. Hi, What do the professionals do when they need to change instrument cluster? This weprom why we test Posted by nsaspook in forum:
