Title The System of SMS of Sending and Receiving Based on MSP430
Abstract
With the rocketing development of the mobile-communication project andexpends of application field of mobile-communication technology, more and more people are paying attentions to the design and application ofGSM SMS of sending and receiving terminal device. The design uses the newest GSM of sending and receiving module TC35I of siemens company,
low power-losing 16-bits microprocessor MSP430F149 of Texas Instrumentscompany in America and delphi language to analyse the principle and application ,characteristic and hiberarchy of TC35I and AT instruction.It designs a circuit of communication between TC35I and MCU;makes outa system of sending and receiving of GSM SMS. The system can send and receive SMS,make a call and communicate with PC; with many advantages:such as low power-losing, small size, liquid crystal display, simply
making and so on; it also can control the state of SMS. The system of car watching and the management of traffic has used it now. It is clear that the system works stabily, operates simply, costs little, makes a good use of channel, with a large content, many kinds of services, keeping a secret, anti-jamming and a good mart future.
