Speaker

PROS supports playing Ring Tone Text Transfer Language (RTTTL) tones on the VEX Speaker as demonstrated below:

init.c:

void initialize() {
  speakerInit();
}

opcontrol.c or auto.c:

void ...() {
  // Play a tune on the speaker
  speakerPlayRtttl("Super Mario:d=4,o=5,b=100:16e6,16e6,32p,8e6,16c6,8e6,8g6,8p,8g,8p,"
