93L56R-CLI

A commandline tool for reading and writing 93L56R serial EEPROMs of the Combination Meter, and ECM, or the IS24C01 EEPROM used in the BIU, using an arduino running my subaru immo sketch.

TODO

• Tests?
• TravisCI or github actions to automate binary creation and publication
• Verbose output only with a flag.

Got all of the understanding of the odometer right here. https://www.rs25.com/forums/f105/t105267-diy-reprogram-odometer-your-swapped-dash.html https://www.rs25.com/forums/f105/1668064-post3.html https://www.rs25.com/forums/f105/3250739-post81.html

Right-Vertical EEPROM contains the odometer on E0 and F0

Odometer value is a 20bit unsigned int, which will overflow at 1048576. The largest usable number is 999999, since the odometer only has 6 decimal places. Not sure how it would react to a number larger than 999999.
