key pad entry

I need to input time values into a porgram on the BS2.
The program has to take input for a specific time to
run a motor. The time can be entered in minutes. Two entrys
one for the run time and another for the delay between the
run cycles need to be entered. Basically the first entry gives the
actual motor ON time. (input from user 10) for 10 minutes. The second
entry is the OFF time of the motor. (say 180 minutes). The motor
should come on for 10 minutes the shut off for 180 minutes then run
again for the 10 and keep doing this until stop switch is pressed.
I found that solutions cubed has a pocketwatch board that can provide
the current time via serial input. I need a way for the user to type
in the two time limits on a key pad. 4 x 4 type would work. My
delima is that I cant find the code to do this with the
memkey device also provided by solutions cubed. Or the code to
do the comparison of start time and stop times.....
any ideas on where to start...??? The motor control portion is
no problem neither is the LCD, The keypad and time calculations
are the big ones..
HELP
thanks

Good morning,
You might want to have a look at our EDE1144 Keypad Encoder IC. It will
allow connection of a 4x4 matrix keypad and provides auto-repeat, keybeep,
and debouncing. Interfaces well to a Stamp because it has a Keypress
signal that allows you time to jump to the Serin routine. Full datasheet
is at www.elabinc.com

Stamp at a decent price.
