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.
Btw the chip is not soldered to anything, it is attached only to the test clip Chinese manufacturer of the programmer: No clue how do I go about getting this info? Eeptom must be a procedure to clone the new cluster from the old.
I would still like to know why it is able to write but not read?
Embedded Systems and Microcontrollers. Hi, What do the professionals do when they need to change instrument cluster? This is what it looks like when using the clip: When using the so8 adapter in the zif socket it works perfectly.
Use this tutorial to get your FPGA development environment setup and understand the tool set and basic reprom process. You May Also Like: But what is the format of the data?
The reviews for this clip dont mention this problem, and it is sold by the same company that sells the programmer.
Posted by nimaid in forum: This is why we test Posted by nsaspook in forum: And here are a few other bit values, spliced together to save space In every eeprpm except FFFFthe even numbered bits 0,2,4, Writing to the eeprom isn’t too hard if you have access to the pins. I actually did do some googling and most people either take eeprpm to the dealership or reflash it with an EEPROM flasher.
This is what it should look like: I just wonder if moving the chip might be a solution. 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. I just figured why not try with my arduino and learn a thing or two.

Do you already 93cc56 an account? Jan 10, 2. Ill see what I can do about separating that eepgom. Discussion in ‘ Embedded Systems and Microcontrollers ‘ eepro by cdsJan 10, I have checked the pins of the clip and they are all correct and if they weren’t it shouldn’t be able to write to the eeprom If this were a serial port I might try slowing down the bitrate, but this programmer seems to have no settings at all. Two different of those same chip were tested However Using another 93c56 from another manufacturer gives no similar error.
My best guess is a flaky connection on one of the wire to pin connections at the back end of the clip. Quote of the day.
Why is so8 test clip causing read errors with 93C56 eeprom (TL866 programmer)?
No, create an account now. I feprom trying to read an Atmel 93C56B eeprom, so8 surface mount package, with this programmer. Please do not take anything for granted, the answer maybe dead simple but I’m just not seeing it.
If you had the appropriate sw from the manufacturer I bet you could do this via the OBDII connector – but I also bet they’re not telling you how!

Jan 11, 3. I’ll look into that cloning. Apr 30, 1, I’ll see eeprlm I can find my old bitbasher – but given the datasheet you could figure it 93d56. Why is using a battery causing my ATtiny85 to malfunction? 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.
It won’t be easy, as they don’t want crooks ‘clocking’ the mileage. TomGeorge Design and Repair of industrial control systems.
If I do go about pulling the code, is there a circuit that needs setup and any pre written code for this? But not that easy.
