Embodiment Construction

[0038] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] The present invention proposes a method for reading EEPROM chip data (the full English name and Chinese name of EEPROM are respectively Electrically Erasable Programmable Read-Only Memory). figure 1 It is a schematic diagram of an embodiment of the EEPROM chip data reading method of the present invention. Such as figure 1 , the EEPROM chip data reading method comprises:

[0040] In step S10, power on or reset the MCU of the external unit; wherein, the full English name and the Chinese name of the MCU are Microcontroller Unit respectively.

[0041] Step S20, reading the EEPROM chip data for the first time after power-on or reset;

[0042] Step S30, when the external unit MCU successfully reads the EEPROM chip data for the first ti...

Abstract

The invention provides an EEPROM chip data reading method, a control system, an air conditioner and a storage medium. The EEPROM chip data reading method comprises the steps that an external computerMCU is powered on or reset on; EEPROM chip data is read for first time after the external computer MCU is powered on or reset on; when the reading of the EEPROM chip data fails for the first time after the external computer MCU is powered on or reset on, the external computer MCU executes a preset IIC bus unlocking process; after the external computer MCU executes the preset IIC bus unlocking process, the EEPROM chip data is read again; when the re-reading of the EEPROM chip data fails after the external computer MCU executes the preset IIC bus unlocking process, a preset external computer control module reset process is executed; and when the re-reading of the EEPROM chip data succeeds after the external computer MCU executes the preset IIC bus unlocking process, an air conditioning unitis controlled to operate normally. According to the EEPROM chip data reading method, the control system, the air conditioner and the storage medium, the reading success rate of the EEPROM chip data can be improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioner control, in particular to an EEPROM chip data reading method, a control system, an air conditioner and a storage medium. Background technique [0002] The operation related parameters of the air conditioner are usually stored in the EEPROM memory chip. After the main board of the air conditioner is powered on, the MCU (micro control unit) reads the operation related parameters stored in the EEPROM memory chip, and controls the operation of the air conditioner unit according to the read operation related parameters. It can be seen that the successful reading of EEPROM data by the MCU (micro control unit) is the basic prerequisite for the normal operation of the air conditioner. [0003] During the operation of the air conditioner, reading EEPROM data may fail due to various reasons. When the existing air conditioner fails to read EEPROM data, there is no corresponding solution, and...
