That's what you get with flea-bay...

I would like to have help or sample basic program to experiment with this board using either a 16F877 or 16F887 chip. The board is complete and has 4 5x7 RG LED modules in place along with 2 switches (power/red or green selector) and 3 additional switches that can be used within the program to select subroutines or text to display.
You'd learn a heck-of-a-lot more by writing code that doesn't work, posting that non-working code, and asking for assistance in figuring out why it doesn't work, than you would if you were to just cut-and-paste somebody else's working code...unless all you really want is instant gratification...
A lot of people here know a lot of things about a lot of stuff. And I will suggest, heavily suggest, starting off simple and slow, blink one led, blink 3 leds, blink 3 leds and control them with a couple of switches, and so on and so on.

Ya, that doesn't work so well..
