Hi all,
I am very new to electronics and only have a very basic understanding. I find myself needing to understand a bit more all the time. Hope someone here can give me some advice.
A bit of background before I ask a few questions, which I hope is ok.
I work in Automotive Diagnostics. Most of my work involves sorting faults in the sensor and supply circuits external to the control units in cars. More and more I find the need to get involved with the control units themselves. For example, if I want to change a control unit it normally needs to be coded or it might need transponder chip keys matched. swapping eeproms can often sort this. Some of this work I can do with pc based software. Basically all the software is doing is reading the eeproms and extracting some code to convert to decimal. There are also a lot of corrupt eeprom problems which could be sorted by copying from another unit the same and editing to suit.
For now I would like to hear of good sources where I can read up a bit on eeproms to gain a better understanding. For example, I dont understand checksums.
Thanks
