基于单片机实现PT2262通用编码器的软件解码

The Software Decoding of Universal Encoder PT2262 Based on SCM

    摘要
  • 摘要: 介绍一种基于STC12C5201AD单片机的PT2262通用编码器的软件解码方法,该方法解除了使用PT2272专用解码芯片和进行地址配对的限制,使得开发人员有了更多的选择.解码结果的片内EEPROM存储使单片机在无线遥控系统的应用得到了扩展.在无信号输入的时候,单片机进入掉电模式大大降低了译码模块的电流,使得该方法更适合于电池供电的嵌入式开发中.该方法不仅能简化电路、节约成本,还提高了无线遥控系统设计的灵活性.

     

    Abstract: Introduce a software decoding method of universal encoder PT2262 based on SCM STC12C5201AD,which relieves the limitation of using exclusive decoder chip PT2272 to match the address,and allows developers to have more choices.The storage of decoding results by EEPROM in the SCM can expand the microcontroller applications in wireless remote control system.The MCU enter Power-down mode when there is No signal input,this can reduces the current of decoding module highly,Makes the method more suitable for the development of battery-powered embedded.This method can not only simplify the circuit,cost savings,but also improve the flexibility of wireless remote control system.
