UC121902-TNARX-A

A Library to control the Samsumg UC121902-TNARX-A LCD module with the Arduino. You can buy it from Pollin.

Installation

See http://www.arduino.cc/en/Guide/Libraries chapter "Manual installation" for installation instructions.

Connect to Arduino

CE, CK and DI are connected to pins on the Arduino. Default values are CE=2, CK=3, DI=4. Multiple displays can be connected. They can share CK and DI but CE should be on a different pin.

Hello World

#include "UC121902-TNARX-A.h"

UC121902_TNARX_A::Display display(2, 3, 4);

void setup() {
  display.begin();
  display.print("Hello :)");
  delay(1000);
}

int count = 0;

void loop() {
  delay(1000);
  display.print("count:", count);
  count++;
}

How to Use The Library

Import

One of the first lines in your Program is this:

#include "UC121902-TNARX-A.h"

###Initialization

UC121902_TNARX_A::Display display(CE, CK, DI);
UC121902_TNARX_A::Display display(); // CE == 2, CK == 3, DI == 4

You can choose one of the lines. You can rename display to use multiple displays.

###Printing

display.print("String");
display.print(1234567890L);
display.print("variable:", variable);
display.print(character, position);

Unknown characters are replaced by '?'. You can also use put and flush:

display.put("String");
display.put(1234567890L);
display.put(character, position);
display.flush();

put does not send commands to the display. flush sends the current state to the display.

Symbols

These Symbols are present on the display:

display.chan
display.mem
display.prog
display.sec
display.bell
display.battery

They have these methods:

display.chan.turnOn();
display.chan.turnOff();
display.chan.isOn();
display.chan.isOff();
display.chan.toggle(); 

display.mem.turnOn();
display.mem.turnOff();
display.mem.isOn();
display.mem.isOff();
display.mem.toggle(); 

display.prog.turnOn();
display.prog.turnOff();
display.prog.isOn();
display.prog.isOff();
display.prog.toggle(); 

display.sec.turnOn();
display.sec.turnOff();
display.sec.isOn();
display.sec.isOff();
display.sec.toggle(); 

display.bell.turnOn();
display.bell.turnOff();
display.bell.isOn();
display.bell.isOff();
display.bell.toggle(); 
display.bell.mute();
display.bell.unmute();
display.bell.isMuted();
display.bell.isUnmuted();
display.bell.toggleMuted(); 

display.battery.empty();
display.battery.isEmpty();
display.battery.full();
display.battery.isFull();
display.battery.halfFull(); 
display.battery.isHalfFull(); 
display.battery.turnOn();
display.battery.turnOff();
display.battery.isOn();
display.battery.isOff();
display.battery.toggle();
