  • 本文介紹的兩款模塊都很小巧，但功能強大，一款是高集成度的OGG播放器方案，另一款是大家都熟悉MP3解碼方案。此次評測的是Adafruit的兩塊板子：Audio FX Sound Board & Music Maker FeatherWing w/Amp

播放一串變化的音符(Adafruit演示程序)

def test_play_loop( ser, looptime ):

print("===Music Start===")

while looptime>0:

i=60

while i<69:

midiNoteOn(ser,0, i, 127);

time.sleep(0.1)

midiNoteOff(ser,0, i, 127);

i=i+1

time.sleep(1)

looptime=looptime-1

ser.close()

print("===Music End ===")

以下為實現(xiàn)播放《獻給愛麗絲》的代碼：
