Hi,does the CY8CPROTO-062-4343W Kit have a PDM example?I can't find a PDM example in the ModusToolBox V1.1.

You can use a PWM with a small period to drive the MCLK for the codec.

We have a ModusToolbox example that implements an audio recorder, but it uses the USB instead of an audio codec.

base on the example code CE220762,now i use one PDM with two mic,if i want to set the PDM_PCM to "shereo" mode,should i use only one DMA transfer record data to I2S TX_FIFO,or i also need two DMA(left and right)?and what else should i configure?

Hi,

We are actually updating the CE220762 to do just want you want. Configuring the PDM to stereo and using a single DMA for the I2S. Attached you find the project.
