Im working on the programming for a scoreboard project and i would like to know if anyone knows the circuit layout and code for a double digit counter?· I'm using a NX1000 board and bs2.· I would also like the counter to respond to a switch input, like on a scoreboard.· Please help!

There are myriad solutions to this problem. If you want to use the 7-segment LEDs on the NX-1000, you'll need to use a multiplexer like the MAX7219 or the MC14489 -- you can find code for both here in the forums (do a search), and StampWorks has a whole experiment with the MAX7219 (download StampWorks and look at the project; it's a coin counter and has lots of code that will help you).
