CC8520: Operation verification of TLV320AIC3263 and CC8520

Hi Conor,

Q1.
Is it possible to connect and operate TLV320AIC3263 and CC8520 via I2S, I2C, or SPI? If so, can I create a program with purepath wireless configurator?

According to datasheet, CC8520 supports:

1. I2S and I2C: Seamless connection and control of external audio codecs, DACs/ADCs and digital audio amplifiers using I2S and I2C
2. SPI:  An external host processor can be connected through SPI and control some aspects of its operation.

Purepath Wireless configurator may be used to create a firmware for CC85xx. The one available on the CC85xx product page should be used: https://www.ti.com/tool/PUREPATH-WL-CFG 

Excerpt:

PurePath Wireless Configurator (PPWC) is a graphical PC tool used with CC85XX devices, and no extra 3rd party tool is needed. PPWC works on precompiled image files. Based on input from the user, PPWC will patch these to generate a downloadable firmware image. The designer will then be able to program the CC85XX device directly from PPWC through the CC Debugger tool (included in CC85XXDK) or output it to an Intel HEX-file (for production programming).

For questions on TLV device, I recommend creating a separate post in the Audio forum: https://e2e.ti.com/support/audio-group/audio/f/audio-forum

Hi Toby,

Thank you for your reply.

I am considering the PurePath Wireless CC8520 and CC8531. These are a bit legacy, so please let me know if there is a new Roadmap or recommended alternatives.

Thanks,

Conor

Hi Conor,

Generally for roadmap questions, we recommend reaching out to a local TI representative, as this information would typically require some form of NDA.

Try here: https://www.ti.com/info/contact-us.html and provide this post as reference if needed.

Thanks,

Hi Toby,

I posted about Q2 on the Audio forum, but did not receive a clear answer.
Would it be possible for you to assign someone in your company who can answer Q2?

Hi Toby,

When creating a control program for TLV320AIC3263 or TLV320AIC3262 and CC8520 using Purepath Wireless Configurator, the model numbers for TLV320AIC3263 and TLV320AIC3262 were not available in the Audio Interface Select device list.

I would like to know how to create a control program for these ICs using Purepath Wireless Configurator.
I am using version 1.4.2 of Purepath Wireless Configurator.

Thanks,

Conor

Hi Conor,

I am looking for who is owning this tool.

Will provide an update by Jun 27.

Thanks,

Hi Conor,

Can you try the following steps?

```

From the PurePath Wireless Configurator download location, enter the audio_devices folder. Copy/paste any of the other audio code file .ppwadd (ex. aic3204 is TI part TLV320AIC3204) and rename it to the new part. Edit the file and "replace all" naming conventions.

In PPWCFG, notice the new Audio Codec device selection. You must rewrite the new .ppwadd contents to match the new device's configuration, as they are not provided by default. This should get you started.

```

Thanks,
Toby
