Hey guys,
i'm working on a real-time information about bus departures.
I use an Arduino with Ethernet Shield and 4 led matrices.
Displaying the text works - as you can see in the attachment (The first letter on the left side is the bus line, the next is the direction and the last is departure time).
The code looks like this:
#include "HT1632.h"
#define DATA 2
#define WR 3
#define CS 4
#define CS2 5
#define CS3 6
#define CS4 7
HT1632LEDMatrix matrix = HT1632LEDMatrix(DATA, WR, CS, CS2, CS3, CS4);
void setup() {
Serial.begin(9600);
matrix.begin(HT1632_COMMON_16NMOS);
delay(0);
}
void loop() {
matrix.clearScreen();
matrix.setTextSize(1);
matrix.setTextColor(1);
if (matrix.width() <= 24) {
matrix.setCursor(0, 0);
matrix.print("");
matrix.setCursor(0, 8);
matrix.print("");
matrix.writeScreen();
} else if (matrix.width() > 24) {
matrix.setCursor(0, 0); // First left
matrix.print("D K");
matrix.setCursor(0, 8); // Second left
matrix.print("E F");
matrix.setCursor(48, 0); // Third left
matrix.print("DE K");
matrix.setCursor(48, 8); // Fourth left
matrix.print("DE H");
matrix.setCursor(24, 0); // First right
matrix.print(" 7'");
matrix.setCursor(24, 8); // Second right
matrix.print(" 9'");
matrix.setCursor(72, 0); // Third right
matrix.print("1749");
matrix.setCursor(72, 8); // Fourth right
matrix.print("1820");
matrix.writeScreen();
}
delay(1000000);
}
To get the real-time, I want to use the source-code of my transport authority, it displays 4 departures and all the information you need:
http://www.ivb.at/smartinfo/ivb_smartinfo_kernel.php?olifServerId=84&autorefresh=20&default_autorefresh=20&routeId=&stopId=Absam%20Dorf&optDir=-1&nRows=4&showArrivals=n&optTime=now&time=&allLines=y&app=sionline
There is no API available. Has anyone an idea how to load the information from the source code to my led matrices?
I've looked up some tutorials, but no one really solved this problem..
Thanks for your help!
