I want play 'beeps' connecting a piezo buzzer to my Beaglebone Black. I am very new to eletronics, so I need some help here, don't know how to operate these sound devices.
-Eletrical circuit: as for the circuit, I am referring to this book/chapter<http://books.google.com.br/books?id=k6FMtlXOQ50C&lpg=PA101&ots=XwRSMXrq8e&dq=beaglebone%20black%20buzzer&hl=pt-BR&pg=PA101#v=onepage&q=beaglebone%20black%20buzzer&f=false>which shows it very well how I should proceed: using a transistor.. -What I don't know is, how do I control the buzzer (say from a C program) to emit sound? -I guess I should configure and use PWM feature of the processor, am I right? -And how do I pragmatically control PWM output? -How could I make it play an given sound file, like a .midi file? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
