STM32是以Cortex-M3为核的处理器，该例程介绍STM32下如何对实时钟RTC进行操作。RTC可保存时间，由电池供电。-Cortex-M3 based STM32-core processor for the routine introduction STM32 how to operate in real-time clock RTC. RTC to save time, by the battery-powered.

利用430自身的捕获功能，设计频率计，捕获精准，最高捕获频率可到1MHz同时430兼有低功耗功能，能搞实现低功耗运行

arm的板子很多人都在用，这种板子更是很多学生在用的实验板，希望对他们有所帮助-arm of the way a lot of people are using, which is the way many students in the experimental boards, and I hope to help them

本人自己制作的JTAG下载线，只用了一片244,可以支持ARM9、Cortex™ -M3、CPLD、FPGA、89S52等。目前这些已经测试通过。性能稳定。但是注意74LS244和74HC244在性能上可能会有些区别-I own the JTAG download cable, only a 244, can support the ARM9, Cortex
