Function Documentation

void play (  u16  Hz  )

Plays a tone in Herz The tone in Herz. 0-17 for switching off. This function should not be invoced directly (just for testing purposes) because it overrides the normal sound and doesn't stop brawling. Parameters: Hz  Definition at line 32 of file robotsound.c. Referenced by playt().

int playi (   )

This function is called from SIGNAL(SIG_OVERFLOW0). Here the sound is playied. It is called every 16,3ms which is the fastest Tick in a sound. Definition at line 78 of file robotsound.c. Referenced by SIGNAL().

int start_sound (  u08 *  soundtostart, u08  override )

With this function you can enable a sound (melodie). The sound bites are in program memory and have the following structure:. [ticks, tone],[ticks,tone],...[0, 0]. One tick is about 16ms and by setting tone to 0 you can make a pause. The tones start at a C [33Hz] and go up 7 octaves. tone = 60 is the standart pitch 440Hz max is 83. a value of 85 plaies rising tones. and 86 does the same downwards. Parameters: soundtostart  A pointer to the sound which is ended by 0,0 override  Set this to one if the sound should replace a playing sound. Definition at line 95 of file robotsound.c. Referenced by do_boredom(), do_sleep(), and main().
