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.

本示例介绍如何使用 ADC3 和 DMA 将从 ADC3 的不断转换的数据传输到内存。ADC3 被配置为连续转换 channel7。每次转换结束时，DMA 传输，在循环模式中，转换后的数据从 ADC3 博士注册到 ADC3ConvertedValue 变量。在此示例中，系统时钟是 144 MHz，APB2 = 72 MHz 和 ADC 时钟 = APB2/2。由于 ADC3 时钟是 36 兆赫和采样时间设置为 3 周期，对 12 位数据的转换时间是 12 周期，所以总转换时间是 (12 + 3） / 36 = 0.41us(2.4Msps)。
