There must be a procedure to clone the new cluster from the old. Apr 30, 1, 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 just figured why not try with my arduino and feprom a thing or two.

Embedded Systems and Microcontrollers. This is why we test Posted by nsaspook in forum: Digital Signal Processing is the mathematical manipulation of an information signal, such as audio, temperature, voice, and video and modify or eeporm them in some manner.

Is there a connector next to this chip which does this? Yes, my password is: Your name or email address: Jan 10, 1.

TomGeorge Design and Repair of industrial control systems. But what is the format of the data? Posted by nimaid in forum: The errors are consistent eeprrom seem to happen with every bit value except FFFF. Why is so8 test clip causing read errors with 93C56 eeprom TL programmer?


Why is so8 test clip causing read errors with 93C56 eeprom (TL866 programmer)?

No, create an account now. You May Also Like: 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 9356 Everything runs on smoke, let the smoke out, it stops running My best guess is a flaky connection on one of the wire to pin connections at the back end of the clip.

Two different of those same chip were tested However Using another 93c56 from another manufacturer gives no similar error. Jan 11, 3.

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. And if so how would I go about doing this? Please do not take anything for granted, the answer maybe dead simple but I’m just not seeing it.

I would still like to know why it is able to write but not read? But not that easy. It won’t be easy, as they don’t want crooks ‘clocking’ the mileage. I am trying to read an Atmel 93C56B eeprom, so8 surface mount package, with this programmer.

Not to mention so many people in the jeep community have arduinos and would benefit from this. Quote of the day.

I have checked the pins of the clip and they are all correct and if they weren’t it shouldn’t be able eepgom 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.

However when I use the test clipit is giving me read errors on every other bit. 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 93c6 new one will have incorrect millage on the odometer.

Is this something the arduino can handle?

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. The reviews for this clip dont mention this problem, and it is sold by the same company that sells the programmer. I actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher.
