 +===== Set tuning parameters =====

 +A tuning (or calibration) parameter for the related board can be written to the EEPROM as seen below. Usually this is integer or floating point values encoded as a raw hex string that is then decoded where it's used such as in IIO Oscilloscope or wherever the parameter needs to be set.
