SDK 17.0.2:How to use the PDM interface

[zhang_jq]

After the call is initialized and started (nrf_drv_pdm_init nrf_drv_pdm_start), the callback is executed only once. It needs to be re-nrfx_pdm_buffer_set each time in the callback. This usage leads to unstoppability

Hi,

I do not fully understand. If you do as described under Using the PDM driver, sampling will be continuous, yes. But it is not unstoppable, as you can stop it by calling nrf_drv_pdm_stop().Please elaborate if this does not answer your question.
