2.3 Keypad Interface Connector

The GLK24064-25 provides a Keypad Interface Connector which allows for up to a ﬁve by ﬁve matrix

style keypad to be directly connected to the display module. Key presses are generated when a short is

detected between a row and a column. When a key press is generated a character, which is associated with

the particular key press, is automatically sent on the Txcommunication line. If thedisplay module is running

in I

C mode, the “Auto Transmit Keypress” function may be turned off, to allow the key presses to remain

in the buffer so that they may be polled. The character that is associated with each key press may also be

altered using the “Assign Key Codes” command, for more detailed information see the Keypad Section, on

page 33.
