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.

本文详细的介绍了基于LPC2000系列处理器的系统的初始化过程，并结合具体代码（在附带的程序中）对重映射作了细致的阐述，这些对于正确的理解和开发基于ARM的嵌入式系统具有重要的意义。-This paper introduces a system based on the LPC2000 family of processors the initialization process, combined with a specific code (in the attached program) made a detailed mapping of the re-elaboration of these for a correct understanding and development of ARM-based embedded system has an important significance.
