To facilitate user input, the GLK240128-25
provides a Keypad Interface Connector which allows a matrix
style keypad of up to twenty-five 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
specific to that key press
is automatically sent on the Tx communication line.
If a synchronous
read method is desired in serial mode*, the “Auto Transmit Keypress”
function can 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
twelve pin header of the Keypad Interface Connector will interface to a variety of different devices
including the
Matrix Orbital KPP4x4 keypad.
*Note:
In I2C mode, the “Auto Transmit Keypress” function should always be on, keypresses should not be polled.
**Note:
The Ground / +5V pin is toggled by the jumper to the right of the keypad connector. Jump pads 1 & 2 for
+5V or 2 & 3 for GND.
