| 摘 要： | 以２８４９型白平衡仪为例，通过分析白平衡仪的工作原理，介绍了２８４９白平衡仪Ｉ＾２Ｃ总线自动调整系统的设计。系统利用ＰＣ机串口接收２８４９白平衡仪的测量结果，并对结果分析处理后，将需要调整的彩电白平衡解码芯片存储单元的地址及数据传给Ｉ＾２Ｃ接口板，由接口板实现与彩电Ｉ２＾Ｃ总线时序与数据的通信，实现了白平衡的自动调节。

| Abstract: | In this paper, by analysing working princple of 2849 type white balance, we intreduce the design of 2849 white balancer I2C husline autoregUlation system. The system uses PC series port to accept the test results of 2849 white balancer. After dealing with the resluts, the system sends the adress and the data of the TV white balance decode chip to I2C busline board. The board communicates with TV I2C busline to realize the white balance autoregulation. |
