Hello Team,
I am working on a project in which I want to used pdm microphone with nrf51822 xxAA and i am using keil u5.
1) So I have picked uart over BLE example from keil pack installer.
2) Then I have included the "nrf_drv_pdm.h" library.
3) After that I have changed #define PDM_ENABLED from 0 to 1 in nrf_drv_config.h
And after doing all these steps when I run build it is showing around 30 errors in nrf_pdm.h file like used of undeclared identifier 'NRF_PDM'.and many more.
Can you please help me/ direct me toward proper solutions.
Below is the build output error:
