NRFX error occur most of the time while taking examples from SDK15 and SDK17

JuzerT

I took the I2S example from SDK15 and while compiling I am getting the following errors. I tried but I am not able to solve it. The same happen when I have taken twi example from SDK15.

Their is a loot of confusion between NRF and NRFX is their any document which can help me solve this issue will be a great help.

compiling main.c...

    I also observed that suppose in nrf_drv_i2s.h we have error which says that the term is undefined and by left clicking that term and by clicking go to the folder where it is defined, it is directed to sdk_config.h but still it is showing error of undefined term then try the below trick to solve the error.

    So for this also try this solution:

    Go to the folder where nrf_drv_i2s.h file is located and place the sdk_config.h file there it will solve the undefined error. Now try building the code it will work.
