这个程序演示了如何使用 PWM 通道 4要输出正弦波脉宽调制信道上的单刃模式。PCLK 设置为 15 兆赫和那里是没有 prescaling 这样 PWM 时钟是 15 mhz。基准利率设置为 256 基地的 100 H 10 所以基地的 PWM 频率处于 15 兆赫/256 = 58.95375 千赫。

语音芯片的驱动程序，1700是替换isd1420 isd25系列的最新产品，音质性能都有提高。isd1730 isd1760全部兼容。如果做语音芯片的话-Voice chip driver, 1700 is the replacement series isd1420 isd25 the latest products, sound quality has to improve performance. isd1730 isd1760 all compatible. If so, then voice chip
