You can control the PCM5102EVM using one of two pieces of software.
You or your customer will need to request access to the PurePath Console software.

Hi,
Let me confirm below.
Code Control is a tool of device configuration?
Does PurePath have a feature of input data generation or sample source data? Is it able to input a data to the PCM5142?
thanks,
Katsu
Hi Katsu-san,
The EVM software cannot generate the audio signal itself. It only configures the EVM to be an audio playback device. You must then play audio on your PC to create the output signal.
In PPC 1.16, select the USB input and configure the jumpers as shown. Now, you can select the TI USB Audio source on your Windows PC sound configuration options (click the speaker icon in the lower right corner of your Windows taskbar). Now the EVM is configured to be a USB audio playback source. You can now play any audio on your PC (Media Player, VLC, youtube, etc.). I use a tone generator website as a quick source. https://www.szynalski.com/tone-generator/

Hi,
I have additional question.
In the customer's experiment, they wonder a mode of CPTCNF1 mode of TAS1020B USB Microcontroller. Is it good in mode4 or mode5?
Could you please tell me how to check it and how to configure the mode?
Best regards,
Katsu
Hi Katsu,
You will need to run a script to configure the EVM to use the USB input. Sorry I forgot that this was necessary. This can be done using codecControl or PPC, but I will show you how to do it with PPC.
1. Launch PPC, choose the PCM5142 as a target, configure the jumpers and switches for USB input as shown on the GUI.
2.Select the "Direct I2C Access" tab. Press the "load" button, and select this .cfg file. Then select "Execute". 8255.PCM5102 Connect to USB.cfg
The EVM is now configured for USB input.
In regards to the TAS1020 controller, I am not an expert with that device. Will your customer be okay with just using the script as I have shown?
Thanks,
Paul
Hi,
Thank you for your support.
We got a connection to EVM, but not confirm input date from USB using your mentioned script. I would like to check the input data from USB.
Is the probing to TP27, TP28 and TP29 of EVM a correct way to check USB data input?
Best regards,
Katsu
