EA eDIPTFT32-A

EXTERNAL KEYBOARD
A keyboard (anything from individual keys to a 8x8 matrix keyboard) can be connected to the I/O- ports.
The command ‘ESC Y M n1 n2 n3’ defines the count of input lines (n1=1..8) and output lines (n2=1..8).
n3 set debounce function with 10ms steps (n3=0..15). Please note that count of digital input and output
lines will be reduced while connecting an external keyboard at the same port.
Each key is connected with 1 output and 1 input. All inputs are terminated with a 20..50k

Ω

 pull-up

resistor. For double-keytroke function decoupling of outputs is necessary. For that please use schottky
diodes (e.g. BAT 46).

Transmitting the keystrokes
At each keystroke, the associated key number (1..64) is transmitted or if a corresponding Matrix-
Macro is defined, Matrix-Macro will be started. The release of the key is not transmitted. If the release
of the key is to be transmitted as well, this can be done by defining Matrix-Macro no. 0.
(see page 17: Responses of EA eDIP).

2x2 Matrix

1x4 Matrix

4x0 Matrix

4x4 Matrix

Examples

- 2x2 matrix: Command ‘ESC Y M 2 2 ..’ defines the 2x2 matrix. Keypad will need input lines MI1, MI2

and output lines MO1, MO2. Output lines are decoupled by diodes; this is for double
keystrokes necessary. 6 input and 6 output lines remain free for other requirements.

- 1x4 matrix: Command ‘ESC Y M 1 4 ..’ defines the 1x4 matrix. Keypad will need output lines MO1..MO4

and a single input line MI1. With that connection 7 input and 4 output lines remain free for
other requirements.

- 4x0 matrix: Using one single output only (physically 4x1 Matrix), all keys can switch to GND. So no

output line is necessary and comman ‘ESC Y M 4 0 ..’ defines 4 input lines onyl. With that
connection 4 input and 8 output lines remain free for other requirements.

- 4x4 matrix: Command ‘ESC Y M 4 4 ..’ defines the 4x4 matrix. Keypad will need input lines MI1..MI4

and output lines MO1..MO4. Output lines are decoupled by diodes; this is for double
keystrokes necessary. 4 input and 4 output lines remain free for other requirements.

.

Calculating of key numbers:

Key_number = (output-1) * count_of_ input 

(output = MOx, input = MIx).
