i m trying to make it play tunes with the piezo speaker. is there an eaiser way instead of just doing "FREQOUT x, xxxx, xxxxx" ?? when i say tunes i mean like jingle bells....in a midi kinda way

You might want to check out Chapter 8 of "What's a Microcontroller" v2.2 - it is entirely about frequency and sound, and introduces·various coding techniques for playing tunes on the piezospeaker more efficiently than one FREQOUT line per note.··The last activity in the chapter·includes an RTTTL Ringtone Player application program.· The book pdf and the MicroMusicWithRtttl.bs2 program are both available for free download from

I am doing the Sound of Music song (Do a Dear...) on my BS2. And the best book I found so far is 'Whats·a Micro Controller" it gets into how to use the FREQ OUT like you mentioned, however it also goes into sound effects and how to use notes in more then one place via short cuts.

Never mind, I just say what Stephanie Lindsay posted.
