To facilitate user input, the LVK204-25
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 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 twelve pin
header of the Keypad Interface Connector will interface to a variety of different devices including the
Matrix Orbital KPP4x4 keypad.
*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.
