配置 STM PWM

编写ARM程序的好帮手！这是ARM指令集！-ARM program write a good helper! This is the ARM instruction set!

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。

Realizing an MP3 player with the LPC2148, using libmad and EFSL This Application Note describes how to integrate the libmad MPEG 1/2 layer 3 library and the Embedded File System Library EFSL in a LPC2148 device to realize MP3 player. The Keil MCB2140 board is used to test the application and the Rowley CrossStudio for ARM has been chosen as a reference tool-chain. -Realizing an MP3 player with the LPC2148, using libmad and EFSL This Application Note describes how to integrate the libmad MPEG 1/2 layer 3 library and the Embedded File System Library EFSL in a LPC2148 device to realize MP3 player.
