Hey I am trying to combine two functions for the AD-SP BF548 ,the LCD and the AUDIO CODEC functionality. I am doing this by altering the sample code file Audio_Loopback. To the project file source files section I added LCD.c and too the headerfiles section i added LCD.h. When trying to compile the project it results in the following error.


"..\..\..\Getting Started Examples\Common\LCD.c", line 161: cc0020:  error:

          identifier "adi_dcb_QueueHandle" is undefined

          DCBQueueHandle = adi_dcb_QueueHandle;




1 error detected in the compilation of "..\..\..\Getting Started Examples\Common\LCD.c".

cc3089: fatal error: Compilation failed

Tool failed with exit/exception code: 1.

Build was unsuccessful.




What is the proper way i should go about added the two functionality's together provided by the example code.


My end goal of the project is too have a lcd display which when you press allows the code within the audio_loopback.c file to process in the input audio to do voice recognition. Coding this all in VisualDSP++ 5.1.
