But datawheet that easy. And if so how would I go about doing this? Is there a connector next to this chip which does this?

National Semiconductor

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? I just wonder if moving the chip might be a solution. Not to mention so many people in the jeep community have arduinos and would benefit from this.

Datasehet, What do the professionals do when they need to change instrument cluster? 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 actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher. I’ll look into that cloning. Ill see what I can do about separating that chip.

But what is the format of the data? Is this something the arduino can handle?

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.

I’ll see if I can find my old bitbasher – but given datashet datasheet you could figure it out.

There must be a dataxheet to clone the new cluster from the old. It may be cheaper and less risky to go to a Cherokee dealer and get him to do 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!

I just figured why not try with my arduino and learn a thing or two. No clue how do I go about getting this info?

I know datxsheet guy here did it with an off the shelf programmer, which is quite expensive compared to the arduino I all ready own. Writing to the eeprom isn’t too hard if you have access to the pins.

Everything runs on smoke, let the smoke out, it stops running It won’t be easy, as they don’t want crooks ‘clocking’ the mileage. Well the xatasheet news is its a late model and I have everything I need from a junkyard for very cheap.
