I've got some problem with one application, where I have LPC2103. I need to sample and replay audio stream in length about 20sec, but audio
interface is in PCM frame coding with 200kHz clock cycle and 16bit width. Data will be stored into external dataflash. Clocks are generated by audio PCM codec. Does anybody have software emulation for PCM or any idea of chip for interfacing between PCM stream and SPI or UART?
