Arduino Holtek HT16K33 library

This library is used to allow an Arduino device talk to the Holtek HT16K33 chip to control a 7-segment based display. Uses the I2C port and the Wired library.

Device connection

• Arduino 5v -> Backpack +5v / +
• Arduino GND -> Backpack GND / -
• Arduino SDA -> Backpack SDA / D
• Arduino SCL -> Backpack SCL / C

Installation

Copy master folder onto your Arduino library

Usage

Simply import the file 'ht16k33.h' into your .ino

#include "ht16k33.h"

And then define the class, plus initilize it on the setup

HT16K33 HT;
void setup(){
  HT.begin(0x00); // I2C address
}

Examples

It's included one complete example that demostrates how to use the library. Tested and working on this devices:
