source code for keypad through lcd display HELP!!!!!

Cline

Hello, im new to this,· i have a ls 204-25 display with keypad attached, i am comunicating well with the display but cannot see the keypad doing anything, dont even know how to test it,·· i placed these commands in the editor

SEROUT 1, 84, [noparse][[/noparse]254]······ 'Command Prefix
SEROUT 1, 84, [noparse][[/noparse]66]······· 'Backlight ON command
SEROUT 1, 84, [noparse][[/noparse]2]········ 'Setting the number of minutes to be on
· SEROUT 0, 84, [noparse][[/noparse]254]······ 'Command Prefix
SEROUT 0, 84, [noparse][[/noparse]65]······· 'key AutoTransmit ON
· SEROUT 0, 84, [noparse][[/noparse]254]······ 'Command Prefix
SEROUT 0, 84, [noparse][[/noparse]85]······· 'key Debounce time command
SEROUT 0, 84, [noparse][[/noparse]8]········ 'key Debounce time nominal of 52ms

i am trying to use the keypad for a password program·,

hello,·

I ran the file but nonething happens,· my out is pin 0···· in·· pin 1

do i need to change them in the program,·· i dont really undertand the code i just cut and paste what works,

i do undestand somethings· serout 1, 84, [noparse][[/noparse]""] etc.



I dont even know if the keypad is hooked up right,· i used a "flat" harddrive cable to connect the keypad to the lcd,· seems like i could test it to see if im getting an input.....

Cline

I am using a lk204-25 rev 1.23 [noparse][[/noparse]matrix orbital] and the 16key pad, both ordered from parallax,

Cline

How can i see if a signal is being sent from the keypad?
