PmWiki | Robots / Find a Ball

Goal

To Show our opponents that not only can we whoop them in the egg hunt, but we can do it while playing a catchy tune.

Notes

Manan: How much time will this waste? We don't want a robot that can play music but is inefficient at the task it is meant to do. This should really only be an added feature that we can add once we finish getting the egg hunt portion to work, and only if this doesn't significantly slow down the robot.

How to play music in WinWVR (one method):

 
void updateMusic(void);

int song_time = 0, song = 0;
int playlist[] = { 4, 5, 4, 5, 0, 1, 2, 3 };
int playtime[] = {6000, 1750, 6000, 1750, 6000, 6000, 6000, 6000 };

//stores all the music:
  int sing[] = { 140, 0, 13, 64, 32, 65, 16, 67, 16, 72, 64, //start Indy
		30, 16, 62, 32, 64, 16, 65, 64, 30, 16, 67,

  //executes the commands from sing[]
  for(int i=0; i < 157; i++)
  {
    cr8_byte_tx( sing[i] ); //sends a byte to the create
  }

// updateMusic() checks to see if a song is done and
// plays the next one if it is.  Returns nothing.
void updateMusic(void){
	if(song_time > playtime[song % 8]){// 6000){
		cr8_byte_tx(141);
		cr8_byte_tx(playlist[song % 8]);
		song_time = 0;
		song++;
	}
	return;
}  //end updateMusic
