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.
#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++;
}
One of the first lines in your Program is this:
#include "UC121902-TNARX-A.h"
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.
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.
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();
