| 摘 要： | 利用单片机控制智能来电显示器，显示器利用低功耗，具有振铃检测、载波检测功能，满足Bell202和V2．3标准的CID芯片HT9032C实现接收来电信息，同时可实现液晶显示、E2PROM存储和语音播报电话主叫号码等功能。以SPI串行接口智能显示键盘控制芯片ZLG7289A为核心设计的键盘电路实现查阅、删除信息。实践表明，显示器外围器件少，抗干扰能力强，方便好用。文中详细介绍了系统的硬件设计和软件流程。特别介绍了主叫识别信息的两种格式和通过串口及模拟串口接收来电信息的两种方法。

| Abstract: | The paper introduces a kind of intellective CID Displayer controlled by MCU which takes advantage of CID chip HT9032C with such features as low power ,meet Bell 202 and V2.3 standard, ringing detection, carrier detection receive, etc. The CID Displayer realizes the functions including liquid crystal displaying, E2PROM storage , broadcasting the CID information and providing query and delete CID information through keyboard circuit controlled by intellective controlling chip ZLG7289A with SPI serial interface, etc. Besides the paper introduces the hardware design and the software design of the whole system, especially illuminates two forms of the CID information and two methods of receiving CID information through serial interface and the simulative serial interface. |
