A PDM buffer or PCM buffer

[Jon-Yang]

Hi  ,Nordic

nrfx_err_t nrfx_pdm_buffer_set(int16_t * buffer, uint16_t buffer_length)

I wonder the buffer is PDM buffer or PCM buffer ?

also want to know that how to convert this buffer to PCM buffer , could you please provider a sample code ?

The PDM unit converts the PDM to PCM data internally (see PS), the resulting buffer will always be PCM.
