一般说来,用户对彩电的要求应是高画质、高音质,并具有多功能、多制式。为了实现这些要求,在彩电设计方面采取了一系列措施,结果使外围电路十分复杂,元器件增多,生产调试困难。然而,采用了I~2C总线控制的彩电使得各电路之间的连接变得很简单,省掉了控制系统中的许多I/O端口,减少了大量元器件和连接线,取消了常规电路中的十几个可调电阻,提高了整机的可靠性,降低了成本。因此,大多数进口彩电都采用了I~2C总线控制技术。
In general, the user requirements for color TV should be high quality, high quality, and has a multi-function, multi-standard. In order to achieve these requirements, a series of measures have been taken in the design of color TV sets. As a result, the peripheral circuits are very complicated, the number of components and devices increases, and the production and debugging are difficult. However, the use of I ~ 2C bus-controlled color TV makes the connection between the circuit becomes very simple, eliminating the many I / O ports in the control system, reducing a large number of components and connections, eliminating the conventional circuit More than a dozen adjustable resistance, improve the reliability of the whole machine, reduce the cost. Therefore, most imported color TVs have adopted I ~ 2C bus control technology.
