CC8520: CC8520 Slave Local Volume up/down and Mute function

Part Number: CC8520

Dear Sir.

I want to use CC8520 Local volume up/down and mute function.

Role is SLAVE.

Does volume up and down work only with MICPGA?

Doesn't it work in ADC volume control?

Because as you know MICPGA use 0dB~+47.5dB

I want to use -15dB ~ +15dB

How can I use the ADC volume function using the built-in volume up / down and Mute function?

I am using PPWC.

I want to create a volume and mute function for the microphone built into the transmitter.

This means that I want to control the voice input from the transmitter by receiving an external key from the ADC volume control block instead of MICPGA.

Please see the pictures.

Hello Kim,

I assume that you are using the AIC3204 (or similar). You are correct that the default audio device definition controls MICPGA volume.

To change the volume control, make a copy of the <install-directory>\audio_devices\aic3204.ppwadd file to your <documents>\Texas Instruments\PurePath Wireless Configurator\audio_devices.

Then modify the volume controls as described in the Audio Device Definition Files help document, and restart PPWC./cfs-file/__key/communityserver-discussions-components-files/667/audio_5F00_device_5F00_definition_5F00_files.html

Dear Eirik

Thank you for your answer.

Too much difficult for me.

Anyway Where can I write Source code???

In PPWC "Audio Device Customize" Tab???

Just typing

regValue |= "read register value" & patch_read_mask;

regValue = patch_reg_data;

??????

Now I use only PPWC to control AIC3204 and CC8520, not external MCU control method.

How can I wirte C source code????

Please tell me how to do this in more detail.

No please let me know as much as possible.

Thank you.
