    Default Laser Software open source

    Hi

    I modified the Popelscan source code and I made an ILDA converter DAC for LPT port.
    I added text vectorizing and a primitive ILDA file type import but I didn't know how to vectorize objects (different shapes draw with point bye point).Also I didn't know to autotrace an image.
    I want to add autotrace and to draw objects (lines and other shapes vectorized with points).
    Is anybody who knows how can I do this ??
    I also modified the RIYA demo player to works with my ILDA converter DAC for LPT port.
    And now I am looking for example or source code (I prefere DELPHI) for editing laser shows.
    In the schematic diagram attached I use the PIC16f84 only for protection of communication of my software, but I never use it. You can use this ILDA converter without this microcontroller.
    Good luck

    What is the point of that PIC controller? It doesn't even appear to be connected to anything in the schematic.

    Edit: Nevermind.. I should have read the entire post first.

    It looks like you have differential outputs for the blanking control. I really don't think it should be differential for the ILDA standard, only 0 to 5V. Since you're only using TTL blanking you actually don't need any amps for this output, just connect it straight to the parallel port. Color- just connects to Gnd.

    The ILDA standard does have differential outputs for color. 5v p-p. So each pin should be in the range of +-2.5v. Some DACs don't do that so that make the + pin on the connector 0-5v and tie the other pin to gnd. The result is the same except when you discount any noise.

    Ah... I see now (finally managed to find the actual ILDA projector standard, it wasn't that easy). It does state that "All signal receivers must have a true differential input stage!", but the output is given as 0 to +5V which isn't a differential output. I guess it would be better to use a differential output, but I have yet to see someone actually do it (but then I haven't looked at the more professional designs yet).

    Edit: Just realized, 0 to +5V can be differential too... I'll just keep quiet about anything electronics related (still learning). :P
