TI中文支持网请教IT的工程师：
用两个PCM1864实现8路采样， 每个PCM1864实现4路单端MIC输入， 32000采样， 16bit。TDM输出。 目前时钟配置正常输出LRCK = 32K BCK = 8192K,但是DOUT一直无数据输出
实现大致框架参考PCM1864手册p73
软件配置如下：（只是列出Master端的1864配置，Slave端配置大致相同）

user151383853：
但是DOUT一直无数据输出, 我觉得先检查检查硬件吧,也许是供电问题, 接触焊接问题也说不定呢

回复 user151383853:
硬件没什么问题，供电，焊接不正确，不然不会时钟正常输出啊
