WAVE shield, closing files

by Fozzie on Mon Mar 18, 2013 10:59 am

I saw a reference in a technical answerto a question to closing the WAV file after it is played. I could not find an example of actually doing that in any of the example scripts. Is it necessary and, if so, how is it done?

Second, is there a guide to what functions are available in the various libraries? For instance, I see that you can say "wave.play" and "wave.stop"...is there a list anywhere to show me what you can do with these objects?

This is from the end of loop() in SampleRateHC.pde:
Code: Select all | TOGGLE FULL SIZE
    playcomplete(file);
    file.close();

Not really. If you look in WaveHC.cpp, each function has a comment block which describes the operation.
