Basic Problem with Max II Board

--- Quote Start ---

I tried to debounce the switches with a Flip-flop, but it didn´t work. Maybe somebody can tell me how to debounce in the CPLD.

I use the Max II Development Board REV. 02....

I could post the project but its just a simple edge-triggered D-FF ....Maybe i have to debounce the Switch in the CPLD even if there is a RC for debouncing.What u think?

HI,

I have a problem while programming the Max II Development Board.

I tried to do a basic positive edge triggered D-Flip-Flop while using the switches and Leds on the Board. I use the schematic. The simulation in Quartus works fine, but after programming the Flip Flop triggers on the positive AND the negative edge!!

Hope you can help me!

Kind regards
