After a spell on other things, I am back to a PIC project, and need to generate a 'Dong' sound (as in "ding-dong", without the ding..) On cost grounds I can't go the ISD route, so I want to store and output a waveform from a 12C PIC. Question is, how can I easily create the table of tones/durations required? As I am tone deaf, trial and error could take a lifetime... Tia Stuart Meier -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
