用LPC213X系列的PWM来产生语音。语音数据来源于PC机转换后得到的。最大可以是16位的。 由于是PWM所以输出端口需要低通滤波才能够得到比较干净的声音。 可以经过修改使用LPC2132以上的ARM的D/A来产生。 This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM. -LPC213X series used to generate the PWM voice. Voice data from the PC after the conversion. It is the largest of 16. Because there is PWM output ports need low-pass filter can be relatively clean voice. It has been modified over the use LPC2132 ARM D/A to produce. This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM.

1.此代码在SDT2.51下调试通过，可以在我的板子ARM DEVELOP BOARD V1.0上面跑！其上电以后LED会闪烁一下，接着串口0会输出一些系统信息 可以通过串口终端与系统交互，可以测试320X240 STN LCD,包括图形显示函数，ascii字符显示函数。-1. This code debugging under the SDT2.51 passed, in my plank ARM DEVELOP BOARD V1.0 above run! After its power LED flashes that went 0 serial output will be some system information through serial terminal and system interaction, can test 320x240 STN LCD, including graphics function, ascii character display function.
