• comp music with pic Sounds - Aka BeepMaster

    Ok, here's one little thing I came to spend time on and turned out to be quite funny, so for the musician, here you go:

    I wanted an easy-er way to create tunes with the sound command, else than testing/programming over 40 times to get the notes right.
    Initial plan was to create everything from a windows apps, then output notes to pic, but finally I was tempted to use the PIC as a sound card...

    Result is, a small application running under windows, showing you a virtual music keyboard and notes supported by the PB sound command.(I did my best to match the real frequencies with the ones emitted by a PIC, but they are not all 100% accurate).
    You can clic the keyboard, and notes will be sent on the serial port to the PIC for playback.
    Of course you can record/delete clicked notes to a list, and in the end ask the software to output a PBasic command line to put into a program.



    not 100% bulletproof tested, but functionnal over here.
    Made at least 6 tunes in less than 15 minutes with it.
    It come pre-loaded with JS Bach Minuet =)

    program EXE is here:

    Code required in the PIC to get the notes is here:

    Code:
    ; sound generator PIC12F683, @20Mhz
    ; testing Sounds, and they wait for Data from seial to play more..
    ; For use with BEEPMaster.exe Program to create tunes
