Feature Request: Method to restore EEPROM values

[philipNoonan]

Like a number of other people here, I've got lots of 65535 / 0xFF / FFFF in my EEPROM data resulting in an unusable $50 sensor. My sensor seemed to be all fine until I used the mlx90640 on a jetson nano. So if the EEPROM can be corrupted by the user - surely it must be possible to restore values to it. At this point, I don't mind if its not factory calibrated EEPROM data - I just don't was a $50 very light paperweight.

Using the C API, I get I2C Read Error! whenever it calls MLX90640_I2CRead() - and zeros are returned from MLX90640_DumpEE(MLX_I2C_ADDR, eeMLX90640).

Using the python bindings it does manage to get to a state where I can dump the EEPROM data, so I can see the values have been corrupted.

Reading through the MLX90640 docs it seems there is a way to upload EEPROM data using the windows-based melexis mlx90640 viewer/controller .exe but could this functionality be included in this library? It would be very helpful to a lot of people here!

Thanks,

Same request here!

For reference, this is the EEPROM data of one of my sensors in a way it can be loaded in a C program:

Warning!
Do not overwrite a working sensor's EEPROM with it as every sensors should have its own calibration data.
