This Arduino library provides an easy way of displaying of numbers (HEX) and pretty much anything. It supports common anode displays and common cathode ones.

I needed a library for displaying numbers into a 7 segment display, and now I have it. I hope it helps.

For binding a Display, you must create an instance of Display7 class. Like this.

// Create the Display object
Display7 myDisplay(7, 8, 9, 10, 11, 12, 13);

// Or create it using an Array.
int pins[7] = {7, 8, 9, 10, 11, 12, 13};
Display7 myDisplay(pins);

If you want to use a common anode display, you can do it by changing the commonAnode property.

myDisplay.commonAnode = true;

• number(): It displays a given number. Supports number up to 15 (displays numbers in traditional 7 segment display HEX).

myDisplay.number(6);

• showAndHide(): Displays a number for a given time, then it turns off.

myDisplay.showAndHide(2, 2600);

• custom(): You feed it with the states of the segments, either it is a common anode display or an common cathode one. It works the same way.

// It displays an "H".
myDisplay.custom(0, 1, 1, 0, 1, 1, 1);

// Using an array
int mySegments[7] = {0, 1, 1, 0, 1, 1, 1};
myDisplay.custom(mySegments);

• test(): It displays a sequence of numbers to test the display.

myDisplay.test();

• clear(): Well, it clears the display.

myDisplay.clear();

To use it, copy-paste the Display7 Folder into your libraries folder. Feel free to contribute or use it.
