AI Technical Summary

Problems solved by technology

In some application scenarios, such as backlight or image quality adjustment, the main and auxiliary systems will perform I2C communication at the same time. At this time, the MCU is both the master device and the slave device. Stuck or disordered state affects system stability and thus affects user experience

Abstract

The invention discloses electronic equipment. The electronic equipment comprises a system of chip (SOC), a microcontroller unit (MCU) and a register (REG), wherein a general purpose input / output (GPIO) is arranged between the SOC and the MCU and used for indicating the communication state between the MCU and the REG, the SOC controls communication between the SOC and the MCU on the basis of the pin level state of the GPIO, and the communication state comprises an idle state and a busy state. Accordingly, control over the communication logic of the two systems is achieved through the pin levelstate of the GPIO, data reading / writing abnormalities caused by a communication conflict are avoided, then the condition of upper software display abnormalities caused by underlying data communicationabnormalities is avoided, and the system stability and the user experience are improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an electronic device and a method for operating the electronic device. Background technique [0002] The I2C (Inter Integrated Circuit, internal integrated circuit) bus is a bus standard widely used in the field of microelectronics communication control, and is used to connect the I2C master and the I2C slave. The master device is used to start the bus to transmit data and generate the clock to open the transmitting device. At this time, any addressed device is considered as a slave device. Usually there is only one master on the I2C bus. [0003] With the continuous increase of TV functions, the system framework of TV tends to be complex, and the realization of a complete function requires multiple systems for I2C data communication. Under this architecture, data anomalies will occur due to the incoordination of communication status between systems. Specifically, with ...
