To facilitate user input, the GLK24064-16-1U
provides a Keypad Interface Connector which allows matrix
style keypad of up to sixteen keys
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 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. The straight ten
pin header of the Keypad Interface Connector will interface to a variety of
different devices including the four by four Matrix Orbital keypad.
*Note:
Ground/+5V is toggled by the rightmost jumper above the keypad. Jump pads 1&2 for +5V or 2&3 for GND.

A unique feature of the GLK24064-16-1U
is the ability to control relays**
and other external devices
using either
one or
six General Purpose Outputs.
Each can source up to 10mA of current at five volts
when on or sink 20mA at zero volts when off.
The two row, fourteen pin header can be interfaced to a
number of female connectors to provide control to any peripheral
devices required.
**Note:
If connecting a relay, be sure that it is fully clamped using a diode and capacitor in order to absorb any
electro-motive force (EMF) which will be generated.
