无线串口在智能终端上的应用

[摘要] 文章介绍了由Silicon Labs的无线收发芯片Si4432以及低功耗单片机C8051F930构成的无线串口收发系统的硬件实现原理以及数据收发流程。在无线透明串口数据收发的基础上，文章提出在无需拆卸智能终端以及开盖操作的前提下，通过无线串口实现对智能终端的嵌入式操作系统、应用软件、播放文件、广告等文件的实时更新的方法。该方法保证了系统长期工作的稳定性，并大大提高了工作效率。

[Abstract] In this paper, we introduce the implementation principle and data transmission process of a wireless serial transceiver system that consists of an Si4432 wireless transceiver chip and low-power C8051F930 microcontroller, both from Silicon Labs. We propose a new way of efficiently updating a) a batch of embedded OSs and b) software of the intelligent terminal at the same time. This updating can be done without having to remove or open the intelligent terminal. It also ensures the stability of the system and greatly improves efficiency.
