用C语言写的STM32F10XX的DEMO程序。

该程序模块中xllp_CPUfreq.s，xllp_freq.c，xllp_intc.s，xllp_freq.h四个文件是修改CPU频率的主要代码，使用前可以将这些文件和xllp目录下的文件编译在一起，以便可以在程序的任何地方调用它们，修改和读取CPU频率主要依靠调用xllp_freq.c文件中的两个函数完成：XLLPSetCoreRunFrequency，xllpGetCurrentFreqSetting。其余代码只是一个调用这两个函数的一个例子，也可以自己重新写一个。为了简便，可以将所有的文件当作一个驱动程序在同一个目录下编译，然后以流驱动的方式加载，再用应用程序控制。

进行arm－linux嵌入式系统开发时，需要将文件烧写到flash上，在网上可以找到win下的烧写程序，但多数情况下开发环境应该是在linux下，烧写程序时切换到win下很不方便，使用该程序可以在linux下直接对flash进行烧写 该程序运行后将一个小的for arm的c程序通过串口传送到arm开发板上，使用该小程序与主机端通信，将主机传送信息烧写到flash上- Carries on when arm- linux inserts the type system development, needs the document fever to write on flash, is on-line may find under win the fever to write the procedure, but in the most situations the development environment should be under linux, the fever writes when the procedure cuts under win not to be very convenient, uses this procedure to be allowed directly to carry on the fever under linux after flash to write this procedure movement to transmit orally a small for arm c procedure through the string delivers on the arm development board, uses this script and the main engine end correspondence, writes the main engine pass-along message pam fever on flash
