Hi,
I am trying to make my own audio-bluetooth board, This is the general schematic, but I have a few questions:
1. I don't know how connect pcm3070 and cc2564. Both datasheets say that both chips support pcm and i2s interfaces, but I just can see the i2s pins in the pcm3070 chip (bclk, wclk, data_in, data_out) and I just can see the pcm pins in the cc2564 chip (fsync, clk, data_in, data_out) I don't know if I can connect fsync-wclk, clk-bclk, data_in-data_out, data_out-data_in, and it would work?.
2. If so, How could I configure the cc2564 chip to work with i2s? By H.I.C.?
3. I read in a previous post that the cc2564 only can be connected to a hfp codec, Is the pcm3070 a hfp codec?.
4. One thing that I don't understand, the audio is interfaced by the i2s port or by the uart to a host-processor, and the host procesor is the one who sends it to the codec, Could I connect the codec directly to the cc2564 ( This is a newbie question, but I understood it from a previous post, so to be sure).
