/*
 * @brief Calibrate the calibration data
 *
 * @param voltage     : Voltage value
 *        temperature : Ambient temperature
 *        cmd         : enterph -> enter the PH calibration mode
 *                      calph   -> calibrate with the standard buffer solution, two buffer solutions(4.0 and 7.0) will be automaticlly recognized
 *                      exitph  -> save the calibrated parameters and exit from PH calibration mode
