Feature request i2c serial eeproms #8

Open orphanfour opened 9 months ago

Would it be possible to implement serial eeprom read/write over i2c? This would be very useful for reverse engineering. I have constructed a 3.3v to 5v bridge using an ISO1541 ic and can access data on a xicor x24c04 serial eeprom but reading/writing the individual bytes one at a time is somewhat useless. If you could add the option to dump and write i2c eeproms to and from a file it would expand the usefulness of the tool a great deal. If you need hardware to test it on i can offer mine. Thanks for everything you have done so far.

Good idea. Flipper Zero have a tool named "SPI Mem Manager" but no "I2C Mem Manager". I will give it a try. Maybe I'll made a "24cXX" dedicated tool inside i2ctools.

RIMG0883 Heres a picture of my adaptor board with the ISO1541 isolator/level converter between the flipper gpio and x24c04 It does work but can only read two bytes at a time with your existing i2c app.
