如果想使用PCM1864输出8通道数据,请问该怎么配置呢?

Other Parts Discussed in Thread: PCM1864EVM, PCM1864

目前应导师要求,需要同时采集八通道(4路左右声道)数据;但是我配置PCM之后仅在LRCK高电平有数据输出,而低电平没有数据输出;请问该怎样配置呢?

目前我用的是PCM1864EVM评估板;

我的配置是:(括号中为寄存器)

PCM作为主机;(0x70)

采用TDM输出;(0x20)

BCK:12.88MHz;(0x26)

LRCK:48KHz;(0x27)

ADC1为VIN2[SE] + VIN1[SE];(0x060x07)

ADC2为VIN3[SE] + VIN4[SE];(0x080x09)

输出设置为:01: 4ch TDM (0x0C)
DOUT1: ch1[L], ch1[R], ch2[L], ch2[R]
DOUT2: ch1[L], ch1[R], ch2[L], ch2[R]
