文章提出并实现了一种在LED屏中嵌入摩托罗拉 G18 GSM手机模块和MSP430F149单片机,通过将 GSM 模块接收到的短信息解码后在 LED 屏上显示出来,从而实现信息的无线发布系统的设计。介绍了系统的硬件组成和固化软件的工作流程,阐述了 MSP430F149 单片机和 MotorolaG18 GSM 手机模块的接口、AT 指令的应用、连续多条短信收发处理的实现、短信 PDU 编解码在单片机上的实现、中英文字符在 IIC 总线存贮器中存取和在 LED 上显示的原理等。
The article proposes and implements a Motorola G18 GSM mobile phone module and MSP430F149 single chip embedded in the LED screen, and displays the short message received by the GSM module on the LED screen to realize the design of the wireless information publishing system. This paper introduces the hardware composition of the system and the workflow of the curing software. The interface between MSP430F149 MCU and MotorolaG18 GSM mobile phone module, the application of AT command, the realization of multiple short message sending and receiving processing, the implementation of short message PDU codec in single chip microcomputer, English characters in the IIC bus memory access and display on the LED principle.
