摘要
为了解决商业显示器的电路中HDMI扩展接口芯片在使用过程中,易受电磁信号干扰或者Android系统中因过多不同设备访问I~2C总线,导致总线读取失败或者读到脏数据,使系统通过分析读取到的脏数据,误判HDMI扩展芯片上的HDMI接口为断开或者接入状态,引发系统弹窗误报信号接入现象等一系列错误操作,本文提出了一种容错和防抖动处理的方案。
In order to solve the problem that the HDMI expansion interface chip in the circuit of the commercial display is susceptible to interference by electromagnetic signals or the I2C bus is accessed by too many different devices in the Android system,resulting in the bus reading failure or reading dirty data,and the system By analyzing the read dirty data,it is misjudged that the HDMI interface on the HDMI expansion chip is disconnected or connected,causing a series of wrong operations such as the system pop-up window falsely reporting signal access.Jitter handling scheme.
