I got it working, and directly connected the module to the Arduino 3,3V Output and the digital Pins set in the program.
The SD Card is a cheap 64 mb from my cellphone formated to FAT.
The files are wave (Mono, 16 bit, 12 khz (16 khz didnt work and caused a "chopper"-like noise).
What I don't get is what the difference between
wtv020sd16p.asyncPlayVoice(0); and
wtv020sd16p.playVoice(0);
with both modes I can do things, blink Led's ... while the sound is playing. What is the difference?
I was hoping to be able to play two sounds at the same time, or at lease pause one sound, play the second an than continue.
But this isn't possible, right?
