优化级别必需为s,其他优化级别也不会导致编译时出错，但会导致运行时出错。原因涉及局部变量分配堆栈处理方式不同，也就是OS_CPU_A.c那个文件中的移植部分。还有就是其他优化涉及的中断自动保存寄存器的数量有所出入。-Necessary to optimize the level of s, other optimization levels will not lead to compile-time error, but it will result in run-time error. Reasons relating to the allocation of local variables, stack processing in different ways, that is, OS_CPU_A.c that the transplanted parts of the file. There are other optimization related to the interruption of the number of registers saved automatically have access to.

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.

应用背景stm32低功耗待机和唤醒，实现低功耗和外部中断唤醒。关键技术我们最终要实现这样一个功能：通过长按（ 3秒） WK_UP按键开机，并且通过DS0DS0DS0的闪烁指示程序已经开始运行， 再次长按该键则进入待机模式的闪烁指示程序已经开始运行。再按一次进入睡眠模式。
