Hi all,

    

Using the TLV320AIC23EVM2 for  configuring the register by SPI,and GUI use our own SPI tool.Now i want to know if my connection is right.

In master mode :

My connection is following:

1)JP1 is connection 1-2;

2) J5 :

    LRCLK-DIR,BCLK-DIR,DIG-LB-EN are all powered down.

   SCLK connect the clk of SPI, SDIN connect the MOSI of SPI.

BR!

    Hello Guo,

    JP1 connection looks good as MODE pin should be set to HIGH for SPI. For J5, this looks good as well. I am curious on the use of the CS pin. This pin is just tied to GND. This pin should be toggled. After the 16 SCLK cycles, the data is latched to the codec on the rising edge of the CS pin. Please refer to the data sheet for the SPI details. 

    Regards,
