Hello, Aseem,

In order to modify the AIC111 volume, you need to access to register PGACREG ( www.ti.com/.../aic111.pdf ). This register is used to modify the PGAC gain.

If you require more information about the c code or configurations of code compose studio, please contact our Code Composer Studio Forum. They have more experience on this.

Thanks a lot Luis. Needed some help in code to set volume. Just needed some coding help to set the volume gain.I Checked the datasheet but still needed to know it I have connected the PINS correct. Please suggest if the pins are connected correctly.

Thanks Again

Hi, Aseem,

Since we don't support the microcontrolers family, we cannot guarantee the pins connection. Could you contact the MSP low-power forum for more details?
