GamePal VHDL Code

VHDL Code For the Gamepal:

GAMEPAL.VHD (main circuit controller)

KEYPAD.VHD (controls the 16 key (4x4) keypad)
VIDEO.VHD (controls the output to the VGA monitor)
DICE.VHD (The dice roller function)
MINTIME.VHD (One minute count-down timer)
MIN3TIME.VHD (Three minute count-down timer)
MIN5TIME.VHD (Five minute count-down timer)

Other Required Files (all of these are memory initialization files):

CHARBANK.MIF
MAINMENU.MIF
TIMER.MIF
DICE.MIF

Special thanks and recognition should be given to Jim Hamblen or Georgia Tech School of Electrical and Computer Engineering. The display engine and character set were supplied by him and can be found here.

The code should be compiled using Altera Max+Plus II software. All of the above files are required in order to correctly compile the GamePal. In order to make the GamePal work on the UP1 education development board you must make the following pin assignments:
