Hi,

I am doing the project which needs to input the PDM in CC2640R2, and I see this link:

http://dev.ti.com/tirex/content/simplelink_cc2640r2_sdk_2_20_00_49/docs/blestack/ble_user_guide/html/voice/voice_platform.html#pdm-driver

But some of the links fail. Can you give me the new links?

Thanks,

Hi Yutong,
Did you try the example from GitHub;

github.com/.../ble_examples

Hi YutongWu,

Which links are failing?

We don't have an example out of the box for CC2640R2 because there is no PDM h/w on the DevKit. I recommend porting the pdmstream example found in CC13x0 SDK to CC2640R2.

dev.ti.com/.../

You should probably be able to easily adapt it for use with a PDM breakout board such as

www.adafruit.com/.../3492

The Github examples are only for I2S.

I mean that I have a PDM microphone and I want to connect it with the CC2640R2. And I see in this link

http://dev.ti.com/tirex/content/simplelink_cc2640r2_sdk_2_20_00_49/docs/blestack/ble_user_guide/html/voice/voice_platform.html#pdm-driver

No external codec is required as the bit stream from a digital microphone can be read directly by the device, and the PDM stream can be processed in software.

The PDM driver uses the I2S hardware module within the CC2640R2 to sample the PDM microphone.

So, I want to make this step in my project (PDM microphone-->CC2640R2)

And some links inside it, like PDM Driver Doxygen or PDM Util Doxygen cannot open.

Thanks,

YutongWu
