wxPerl LED Dot Matrix Display Panel

by jmlynesjr (Pilgrim)
on Mar 14, 2013 at 20:15 UTC ( #1023548=CUFP: print w/ replies, xml ) Need Help??

This code simulates an old fashioned 5x7 LED Dot Matrix Display Panel. This is a reimplementation of a C++ wxWidgets program by Christian Gr�fe (info@mcs-soft.de).

The demo app displays 7 panels to demonstrate all the options supported: 7 Color pallets, Upper/Lower case & special characters, Scrolling, Inverse video, etc. The demo uses about 35% of the CPU on my old ThinkPad and has a fair amount of flicker, it's "blit"ing a whole lot of individual LEDs. Maybe it will update smoother on a more modern PC. A single panel display should look pretty good.

The modules are: LedPanelApp.pl, LedPanelDisplay.pm, LedPanelMatrix.pm, LedPanelColourTbl.pm, & LedPanelCtbl.pm.

Need a stock ticker or retro display? Give it a try.

    To eliminate the need for seperate files add
    BEGIN { $INC{'LedPanelDisplay.pm'} = $INC{'LedPanelMatrix.pm'} = $INC{'LedPanelCtbl.pm'} = $INC{'LedPanelColourTbl.pm'} = __FILE__; }

    Your window is unclosable, you forgot  $event->Skip; in onPaint

      Also, without $event->Skip; in onPaint there is no animation, the marqee doesn't scroll or blink :) the blinking is unintentional

    Thanks for the feedback. I did forget the skip. I'll make the change. On my system the window can be closed and all the panels scroll(???).
