摘要
通过对红外遥控器发射编码的分析，提出了一种以MSP430F149为核心的通用型智能红外逻辑分析仪，实现了对所有38K红外遥控器编码的测量和分析功能。在方案中采用测量脉冲宽度的方法，提供了被测红外遥控器编码的所有脉宽信息和波形，并对一些已知的编码格式提供了详细的编码信息。通过对不同遥控器（空调、电视和VCD机的遥控器）信号进行分析测试，本方案的通用型智能红外逻辑分析仪具有使用范围广、分析处理功能强和使用简便等特点。
Through the analysis of the infi＇ared coding, I presented a design method of a universal intelligent infrared logic analyzer with a core of MSP430F149, performing the measure and analytical function for all the 38K infared coding. In the scheme,with the method of measuring the pulse width, I provided measured infrared remote control coding information and all the information of pulse width and waveforms, and also provided detailed coding information for some of the known encoding information. According to the signal analysis test of different remote controls （air conditioners＇, televisions＇ and VCDs＇）, the universal intelligent infrared logic analyzer has the characteristics of wide use, powerful analytical functions, simpleness of use, etc.
