I am trying to get the Sure 3208 running from my Arduino Uno using this library MilesBurton.com. I'm having trouble getting everything wired correctly so nothing is lighting up yet. As far as I can tell, I need to wire +5v>Sure 12, GND>Sure 8, Arduino 4>Sure 3, Arduino 10>Sure 5, Arduino 11>Sure 6. Am I missing anything? I can feel the Sure controller chip heat up so I think it's getting power, but it must not be getting data. Any help is greatly appreciated. Thanks!
I ended up scrapping that library. I think it was written for use with an older LED Matrix Controller. I ended up using the Adafruit code for a 1632 display and reworking it to drive my 3208. Here's the link: GitHub - adafruit/HT1632: Arduino library code for HT1632(C) matrix panel driver chips, and the panels we have in the Adafruit shop
I recently had a play around with these displays and in case you are interested here is the general information for connecting the display up to Arduino.
http://scuola.arduino.cc/en/content/interfacing-arduino-uno-sure-electronics-led-dot-matrix-based-ht1632c-controller
There is an interesting LED_image_drawing_utility in the Image drawing folder of the HT 1632 library. This is what the Blinking_heart code uses.
Download the HT1632 Library here -
I also attached an image of the ribbon cable pinout. For one display use the connector next to the dip switch on the back on the 3208 and set switch 1 on with 2,3 and 4 all switched off as these are for cascaded displays.
Here is the scrolling text code.

Pin 12 to VCC

#include <font_5x4.h>
#include <HT1632.h>
#include <images.h>
int i = 0;
int wd;
void setup () {
// Setup and begin the matrix
// HT1632.begin(CS1,WR,DATA)
HT1632.begin( 9, 10, 11);
// Give the width, in columns, of the assigned string
// FONT_5x4_WIDTH and FONT_5x4_HEIGHT are parameter specified in the "font_5x4.h" file
wd = HT1632.getTextWidth("I hope that you enjoy playing around with these Sure 3208 displays Doc !", FONT_5X4_WIDTH, FONT_5X4_HEIGHT);
}
void loop () {
// Font rendering example
HT1632.drawTarget(BUFFER_BOARD(1));
HT1632.clear();
HT1632.drawText("I hope that you enjoy playing around with these Sure 3208 displays Doc ", 2*OUT_SIZE - i, 2, FONT_5X4, FONT_5X4_WIDTH, FONT_5X4_HEIGHT, FONT_5X4_STEP_GLYPH);
HT1632.render();
i = (i+1)%(wd + OUT_SIZE * 2);
delay(200);
}
And the Blinking_heart code -
#include <HT1632.h>
#include <Images.h>
void setup () {
HT1632.begin(9, 10, 11);
// Where pinCS1, pinWR and pinDATA are the numbers of the output pins
// that are connected to the appropriate pins on the HT1632.
}
void loop () {
HT1632.drawImage(IMG_HEART, IMG_HEART_WIDTH, IMG_HEART_HEIGHT, (OUT_SIZE - IMG_HEART_WIDTH)/2, 0);
// The definitions for IMG_HEART and its width and height are available in images.h.
// This step only performs the drawing in internal memory.
HT1632.render();
// This updates the display on the screen.
delay(1000);
HT1632.clear();
// This zeroes out the internal memory.
HT1632.render();
// This updates the screen display.
delay(1000);
}
I had previously prepared this information for someone else on the forum but you may find some of it useful

Thanks Pedro! I was wondering if you stumbled across any code I could use to reverse the cathode/anode direction so it can work with the Green display. It seems like the text I draw is rotated 90deg and mirrored vertically. I saw there was a patch for the Miles Burton code, but I haven't seen anything for the other libraries. Thanks!
Edit: I'm also having trouble compiling the code from that library. I keep getting a few errors:

So I see that there's this patch for the Miles Burton library that allows you to use it for the Green 3208 display. Is there any way to patch the Adafruit library to remap the LED Array?

Sorry my coding skills are limited. Maybe someone else can help you, good luck 8)
Hey I'm new as well with this Sure 3208. I think my display is malfunctioning as when I connect the 5V from arduino to the IDC cable and the Ground from arduino to the IDC cable my arduino uno turns off which means that there is a short. Can anybody please help me ?
