I just figured why not try with my arduino and learn a thing or two. Why is using a battery causing my ATtiny85 to malfunction? This is why we test Posted by nsaspook in forum: Quote of the day.

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

Everything runs on smoke, let the smoke out, it stops running Nov 5, 19 0. Well the good news is its a late model and I have everything I need from a junkyard for very cheap.

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’ll see if I can find my old bitbasher – but given the datasheet you could figure it out. I am trying to read an Atmel 93C56B eeprom, so8 surface mount package, with this programmer. Is there a connector next to this chip which does this?

The errors are consistent and seem to happen with every bit value except FFFF. Not to mention so many people in the jeep community have arduinos and would benefit from this.

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 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.


Embedded Systems and Microcontrollers. Use this tutorial to get your FPGA development environment setup and understand the tool set and basic development process. If I do go about pulling the code, is there a circuit that needs setup and any pre written code for this?

The test clip works fine when writing data also. 93d56 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. Why is so8 test clip causing read errors with 93C56 eeprom TL programmer?

flashing a 93c56 EEPROM with arduino

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. Your name or email address: I’ll look into that cloning. Jan 11, 3. Posted by nimaid in forum: I actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher.

But what is the format of the data? And here are a eeprmo other bit values, spliced together to save space In every case except FFFFthe even numbered bits 0,2,4, Do you already have an account?

My best eepdom is a flaky connection on one 93cc56 the wire to pin connections at the back end of the clip. Apr 30, 1, TomGeorge Design and Repair of industrial control systems.

I just wonder if moving the chip might be a solution.

Jan 10, 2. 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. Btw the chip is not soldered to anything, it is attached only to the test clip Chinese manufacturer of the programmer: Two different of those same chip were tested 39c56 Using another 93c56 from another manufacturer gives no similar error.

There must be a procedure to clone the new cluster from the old. It won’t be easy, as they don’t want crooks ‘clocking’ the mileage. 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 eerom to have no settings at all.

Discussion in ‘ Embedded Systems and Microcontrollers ‘ started by cdsJan 10, Jan 10, 1. The reviews for this clip dont mention this problem, and it is sold by the eepeom company that sells the programmer.

Yes, my password is: This is what it looks like when using the clip:
