I~2C总线是英文“inter integrated-circuit bus”的缩写,常见的中文译名有:集成电路间总线或内部集成电路总线。I~2C总线是一种串行总线系统,CPU电路上的I~2C总线仅由两根线组成:一根串行时钟线(SCL)和一根串行数据线(SDA)。CPU利用串行时钟线发出时钟信号,利用串行数据线发送或接收数据。采用I~2C总线控制技术的控制系统电路,外部结构简单、故障率低,但电路的工作原理却极为复杂。本文浅谈I~2C总线彩电调整与故障诊断方法。
I ~ 2C bus is English “inter integrated-circuit bus” abbreviation, the common Chinese translation are: IC bus or the internal integrated circuit bus. The I ~ 2C bus is a serial bus system. The I ~ 2C bus on the CPU circuit consists of only two wires: a serial clock line (SCL) and a serial data line (SDA). CPU clock signal using the serial clock line, the use of serial data cable to send or receive data. I ~ 2C bus control technology using the control system circuit, the external structure is simple, low failure rate, but the circuit’s working principle is extremely complex. This article talk about I ~ 2C bus color TV adjustment and fault diagnosis method.
