电视机的I2C总线系统由主控电路微处理器、被控电路和总线数据传输电路三部分组成。任何一部分电路元件发生故障,都会对I2C总线系统的运行和控制造成影响,轻者造成功能丢失或控制障碍,重者造成“死机”。当检查到微处理器输出的SDA、SCL输出电压异常时,可采用“二分为三分割法?
The I2C bus system of the TV is composed of the main control circuit microprocessor, the controlled circuit and the bus data transmission circuit. The failure of any part of the circuit components will affect the operation and control of the I2C bus system, causing the loss of functions or the control of the system. When the microprocessor to detect the output of SDA, SCL output voltage anomalies, can be used "divided into three divided?
