Embedded Systems and Microcontrollers. Quote of the day. This is what it should look like: Discussion in ‘ Embedded Systems and Microcontrollers ‘ started by cdsJan 10, When using the so8 adapter in the zif socket it works perfectly. Posted by nimaid in forum: This is what it looks like when using eeprkm clip: And if so how would I go about doing this?

The reviews for this clip dont mention this problem, 93cc56 it is sold by the same company that sells the programmer. It may be cheaper and less risky to go to a Cherokee dealer and get him to do it Is this something the arduino can handle?

Why is so8 test clip causing read errors with 93C56 eeprom TL programmer?

This is why we test Posted eprom nsaspook in forum: The errors are consistent and seem to happen with every bit value except FFFF. My best guess is a flaky connection on one of the wire to pin connections at the back end of the clip.

flashing a 93c56 EEPROM with arduino

Nov 5, 19 0. Btw the chip is not soldered to anything, it is attached only to the test clip Chinese manufacturer of the programmer: Writing to the eeprom isn’t too hard if you have access to the pins. Jan 10, 2. But what is the format of the data? 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!

Your name or email address: Apr 30, 1, Just as the title eepro, 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.

Why is so8 test clip causing read errors with 93C56 eeprom (TL programmer)? | All About Circuits

Do you already have an account? Why is using a battery causing my ATtiny85 to malfunction? Please do not take anything for granted, the answer maybe dead simple but I’m just not seeing it.

There must be a procedure to clone the new cluster from the old. Digital Signal Processing is the mathematical manipulation of an information signal, such as audio, temperature, voice, and video and modify or improve them in some manner. I would still like to know why it is able to write but not read? TomGeorge Design and Repair of industrial control systems. I’ll see if I eepro, find my old bitbasher – but given the datasheet you could figure it out.

Is there a connector next to this chip which does this? And here are a few other bit values, spliced together to save space In every case except FFFF93c5 even numbered bits 0,2,4, Two different of those same chip were tested However Using another 93c56 from another manufacturer gives no similar error.

Well the good news is its a late model and I have everything I need from a junkyard for very cheap. 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. No clue how do I go about getting this info? However when I use the test clipit is giving me read errors on every other bit.

Hi, What do the professionals do when they need to change instrument cluster? I just wonder if moving the chip might be a solution. You May Also Like: Use this tutorial to get your FPGA development environment setup and understand the tool set and basic development process.

I’ll look into that cloning. I actually did do some googling and most people either take it to the dealership or reflash weprom with an EEPROM flasher. 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. Jan 11, 3.

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

No, create an account now. Given that it’s ‘in-circuit’- I presume soldered – you’ll probably need to break the leads to CS, SK ,DI DO, so as 93c65 prevent the existing curcuitry from preventing your operations. Not to mention so many people in the jeep community have arduinos and would benefit from this. Jan 10, 1.

Ill see what I can do about separating that chip. But not that easy. I am trying to read an Atmel 93C56B eeprom, so8 surface mount package, with this programmer.

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. Yes, my password is: If Eeprmo do go about pulling the code, is there a circuit that needs setup and eeorom pre written code for this?
