/******************************************************************************
Displays a text on the display scrolling from right to left
[email protected]
Original Creation Date: Oct. 18, 2019
This code is Beerware; if you see me at the local,
and you've found our code helpful, please buy us a round!
Hardware Connections:
Connect DOGM128-6 to Arduino UNO. Use Hardware SPI.
SI = 11 (Hardware SPI)
SCLK = 13 (Hardware SPI)
CS = 6
A0 = 8
RESET = 9
Backlight (if needed) is connected via a transistor to pin 10)
Distributed as-is; no warranty is given.
******************************************************************************/
#include <DogGraphicDisplay.h>
#include "ubuntumono_b_16.h"

#define BACKLIGHTPIN 10

DogGraphicDisplay DOG;

void setup() {
pinMode(BACKLIGHTPIN, OUTPUT); // set backlight pin to output
digitalWrite(BACKLIGHTPIN, HIGH); // enable backlight pin

DOG.begin(6,0,0,8,9,DOGM128); //CS = 6, 0,0= use Hardware SPI, A0 = 8, RESET = 9, EA DOGM128-6 (=128x64 dots)

DOG.clear(); //clear whole display
}

void loop() {
static int offset=DOG.display_width(); // static variable with the size of the display, so text starts at the right border

DOG.string(offset,3,UBUNTUMONO_B_16,"Hello to the scrolling World!"); // print "Hello World" in line 3 at position offset

offset--; // decrasye offset so text moves to the left
if(offset<-232) offset=DOG.display_width(); //our text is 232 pixels wide so restart at this value

delay(40); // wait a little bit
