TomGeorge Design and Repair of industrial control systems. This is why we test Posted by nsaspook in forum: I just figured why eeprmo try with my arduino and learn a thing or two.

Jan 10, 1. The reviews for this clip dont mention this problem, and it 93c65 sold by the same company that sells the 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. Just as the title states I wish eepdom flash a 93c56 EEPROM in my jeep cherokee gauge cluster because my old gauge cluster has malfunctioned and the new one will have incorrect eeprrom on the odometer. 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 am trying to read an Atmel 93C56B eeprom, so8 surface mount package, with this programmer.

It won’t be easy, eepom they don’t want crooks ‘clocking’ the mileage. I’ll see if I can find my old bitbasher – but given the datasheet you could figure it out.

Posted by nimaid in forum: My best guess eepro, a flaky connection on one of the wire to pin connections at the back end of the clip. This is what it looks like when using the clip: And if so how would I go about doing this?

Is there a connector next to this chip which does this? Quote of the day. Everything runs on smoke, let the smoke out, it stops running Is this something the arduino can handle? Writing to the eeprom isn’t too hard if you have access to the pins. Your name or email address: Jan 10, 2.

I just wonder if moving the chip might be a solution. I actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher. No, create an account now. deprom

flashing a 93c56 EEPROM with arduino

There must be a procedure to clone the new cluster from the old. Well the good news is its a late model and I have everything I need from a junkyard for very cheap.

Two different of those same chip were tested However Using eerpom 93c56 from another manufacturer gives no similar error. Do you already have an account? 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!

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

Btw the chip is not soldered to anything, it is attached only to the test clip Chinese manufacturer of the programmer: Ill see what I can do about separating that chip. The test clip works fine when writing data also.

Not to mention so many people in the jeep community have arduinos and would benefit from this. Embedded Systems and Microcontrollers. I have checked the pins of the feprom 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.

If I do go about pulling the code, is there a circuit that needs setup and any pre written code for this?

Discussion in ‘ Embedded Systems and Microcontrollers ‘ started by cdsJan 10, Please do not take anything for granted, the answer maybe dead simple but I’m just not seeing it.

Digital Signal Processing is the mathematical manipulation of an information signal, such as audio, temperature, voice, and video and 39c56 or improve them in some manner. 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.

Why is using a battery causing my ATtiny85 to malfunction?
