摘要
为了实现嵌入式手持终端系统的功耗低、体积小、性能稳定的需求,以TI公司的MSP430F449的16位低功耗微控制器为中央处理单元,Semtech公司的SX1233为射频收发单元,设计了一种能广泛应用于餐饮、物流、无线抄表等领域的低成本、超低功耗的无线手持终端设备。分析了系统的功耗和编程特点,给出了系统软件的设计方案。实测结果表明,所设计的无线手持终端设备性能稳定、灵活可调,达到了设计要求。
In order to satisfy the PDA＇s requirement of the low power, small volume and high stability, the wireless PDA based on MSP430F449 of TI and SX1233 of Semtech Co. is designed, which is widely used in eatery, logistics and meter reading. The power consumption and program method of the system are analyzed, and the design of the software is given. Test results show that the performance of this PDA is stable and satisfy for the design requirements.
