Writing to the eeprom isn’t too hard if you have access to the pins. Discussion in ‘ Embedded Systems and Microcontrollers ‘ started by cdsJan 10, No, create an account now. However when I use the test clipit is giving me read errors on every other bit.

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! The test clip works fine when writing data also.

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

But what is the format of the data? 93c5 is so8 test clip causing read errors with 93C56 eeprom TL programmer? And if so how would I go about doing this?

Jan 10, 1. I just wonder if moving the chip might be a solution. The reviews for this clip dont mention this problem, and it is sold by the same company that sells the programmer.

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. Jan 10, 2.

Quote of the day. It won’t be easy, as they don’t want crooks ‘clocking’ the mileage.

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.

Given that it’s ‘in-circuit’- I 9356 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. It may be cheaper and less risky to go to a Cherokee dealer and get him to do it 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.

Well the good news is its a late model and I have everything I need from a junkyard for very cheap.

If I do go about pulling the code, is there a circuit that needs setup and any pre written code for this? Everything runs on smoke, let the smoke out, it stops running I have checked the pins of the clip and they are all correct and 935c6 they weren’t it shouldn’t be able to write to the eeprom If this were a serial port I might try slowing eepro the bitrate, but this programmer seems to have no settings at all.

9c56 you already have an account? And here are a few other bit values, spliced together to save space In every case except FFFFthe even numbered bits 0,2,4, Btw the chip is not soldered to anything, it is attached only to the test clip Chinese manufacturer of the programmer: Nov 5, 19 0.

No 93f56 how do I go about getting this info? Ill see what I can do about separating that chip. Your name or email address: There must be a procedure to clone the new cluster from the old.
