1.微处理器I2C总线系统保护电路彩电I2C总线保护功能是通过I2C总线系统来实现的,因此其保护电路的方框图其实就是I2C总线系统的方框图。常见的I2C总线彩电保护电路方框图如图2(图见上期)所示。主要由被控小信号处理电路、信息传输I2C总线系统、智能控制电路微处理器、保护执行电路和保护提示电路等几部分组成。
1. microprocessor I2C bus system protection circuit color TV I2C bus protection is achieved through the I2C bus system, so the block diagram of the protection circuit is actually a block diagram of the I2C bus system. Common I2C bus color TV protection circuit block diagram shown in Figure 2 (see the previous period). Mainly controlled by small signal processing circuit, I2C bus information transmission system, intelligent control circuit microprocessor, the protection of the implementation of the circuit and protection prompt circuit and other parts.
