Forum Post: RE: PCM5142 EVM GPIO Output

Hello　Dave-san,

Thank you for your information.

I tried to send to you pfw file , but I couldn't  send it.

So I will send attached as image file first .

This process flow is just test circuit , not final.

In step 7, what DoutPin was selected in the In step 7, what DoutPin was selected in the Design Properties window??

⇒Where is DoutPin  in the  Design Properties window?

    I checked only Gpio_Output_1 component.

    Then I changed  "Interrupt Pin"  GPIO⇔Dout  in the Properties window.

 What value was selected under DigitalVolu? 

⇒I set only VOL in the figure below.

　Is there a component of DigitalVolu else?

In case of direct control, you need to also set all of the volume and mixer values shown in figure 71 on page 55 of the datasheet. I think the default values are off.

⇒I changed direct control only step 11 and 12.(GPIOsetting)

   So I think same setting of your suggestion.

Please teach me  how to set  GPIO out through DSP control.

Best Regards,

Y.Hasebe
