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.
