I got the eval board. I want to control this IC with MCU through I2c port. I used the Digital MIC as input.
Now, I sat the REG as follow:
R0=0x01;//Core Clock enabled
R1=0x20;//Digital MIC input
R15=0x01;//Serial port master mode
R19=0x14;//Digital MIC input enable, ADCs off
R39=0xA0;//LRCLK & BCLK pull-up
R66=0x02;//Digital clock generator 1 on
After these setting, BCLK generate a 3.08MHz wave, and the Digital MIC data output is OK(PDM).
I read the data of some registers by I2C. Those data followed my setting.
How can I get the value of Digital MIC through I2C?
I am sorry, my English is not well. But I am really need your help!
