2.2 Keypad Interface Connector
The GLK12232-25 provides a
Keypad Interface Connector
which allows for up to a four by four 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 Tx communication line. If the display module is running
in I2C mode, the “Auto Transmit Keypress” function may be turned o
ff, 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 detai
led information see the
Keypad Section, on
page 35.
