See my keypad.zip file located on my webpage at: http://redrival.com/mcgahee This file includes commented assembly file, schematics, and pcb layout. Requires free Adobe Acrobat viewer. Implements a 4x4 keyboard design. Has Mastercode and several User Codes. Master code can be used to change User Codes. There is a Factory Mastercode that cannot be changed, and a User Mastercode that *can* be changed. User Codes are kept in eeprom. Uses either a 16c84 or 16f84. Fr.

Can anyone direct me to a page on the net with some sourcecode(mpasm) that I will be able to trigger a relay on a correct pin entry and I want to be able to change the pin as well from the pad...
