Copy the following source files into your project's source files folder:

  • app_tone_textfile_sdcard.c
  • app_tone_textfile_sdcard.h

Copy them from apps/training/solutions/audio_player/audio_player_lab2/dev_files to apps/training/solutions/dev/audio_player/audio_player_lab2/firmware/src.

Since you are retaining the app.c and app.h files from audio_player_lab1, you need to change some of the function names to correspond with the newly included app_tone_textfile_sdcard.c file.

Open the file app.c and change the name of the function prototypes.
