I`m using a Alphanumeric Display from elecfreaks (Octopus). I follow the instruction for wiring and try to run the sketch that they provide to test the display, but it is not working. Any ideas why?
Impossible to read your code. We see no connections. They?? no. You!

Most likely something wasn't done correctly. That's about all we can tell without more information.

// Demo the quad alphanumeric display LED backpack kit
// scrolls through every character, then scrolls Serial
// input onto the display
#include <Wire.h>
#include "Adafruit_LEDBackpack.h"
#include "Adafruit_GFX.h"
Adafruit_AlphaNum4 alpha4 = Adafruit_AlphaNum4();
void setup()
{
Serial.begin(9600);
alpha4.begin(0x70); // pass in the address
}
void loop()
{
alpha4.writeDigitRaw(0, 0xFFFF);
alpha4.writeDigitRaw(1, 0xFFFF);
alpha4.writeDigitRaw(2, 0xFFFF);
alpha4.writeDigitRaw(3, 0xFFFF);
alpha4.writeDisplay();
delay(500);
alpha4.clear();
alpha4.writeDisplay();
delay(500);
}
that is the code, which provided to test the display. Thanks for Replying.
