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 have solved the issue.

    On opening file location of the sdk_config.h file from the code i found that it was calling the sdk_config.h file which is located at

    C:\Keil_v5\ARM\ARMCC\include and this file doesn't include the terms that are undefined in the I2S example code.

    So I copied the sdk_config.h file from sdk15 and paste it at location C:\Keil_v5\ARM\ARMCC\include and then building the code all the errors were gone.

    The code was build successfully with zero errors.

    Que: What was the issue?

    Ans: The sdk_config.h file it was calling was the file of sdk8  which doesnot include the term in sdk15 (ofcourse sdk15 is updated version of sdk8).

    so just by calling the correct sdk_config.h file from sdk15 solved the issue.
