Parameter calculation method and device of driving chip and medium

Abstract

The invention discloses a parameter calculation method and device of a driving chip and a medium, and relates to the technical field of communication networks, and the method comprises the steps: obtaining initial configuration data corresponding to the driving chip, and writing the initial configuration data into a register of the driving chip; performing calibration processing on the driving chip to obtain a parameter calibration point; based on the parameter calibration point and a register read value corresponding to the driving chip, a target value corresponding to the parameter of the driving chip is obtained, and the target value is used for representing the current actual size of the parameter. The invention aims to enable the lower PON of the FTTR main gateway to work normally under the condition that an EEPROM (Electrically Erasable Programmable Read-Only Memory) is removed from the driving chip, and meanwhile, compared with a parameter calculation method of a current driving chip with the EEPROM, the method has the advantages that real-time calibration is realized, the parameter calculation precision is improved, and error accumulation caused by the EEPROM is eliminated by setting the calibration points and removing the EEPROM.
