7 Segment Display Library

A powerful but easy to use versatile 7 Segment Library for the arduino environment.

Downloading the library

One can easily install using arduino library manager or one install using the zip file installtion method

API Reference

• Set Pin A

  void setPin1(uint8_t pin);
  void setPinA(uint8_t pin);

• Set Pin B

  void setPin2(uint8_t pin);
  void setPinB(uint8_t pin);

• Set Pin C

  void setPin3(uint8_t pin);
  void setPinC(uint8_t pin);

• Set Pin D

  void setPin4(uint8_t pin);
  void setPinD(uint8_t pin);

• Set Pin E

  void setPin5(uint8_t pin);
  void setPinE(uint8_t pin);

• Set Pin F

  void setPin6(uint8_t pin);
  void setPinF(uint8_t pin);

• Set Pin G

  void setPin7(uint8_t pin);
  void setPinG(uint8_t pin);

• Set Pin DP (Decimal Point Pin)

  void setPinDP(uint8_t pin);

• Set the type of the display used (CATHODE | ANODE)

  void setType(unsigned int type); //values accepted are CATHODE or ANODE

• Displaying no to the display

  void setNumber(uint8_t number, bool dot=false);

• Displaying alphabet to the display

  void setCharacter(char character, bool dot=false);

• Displaying custom character to the display

  void setCustomCharacter(bool customCharacter[]); // The customCharacter array length could be either 7 or 8 elemnts long

• Displaying a range of numbers after a delay

  void displayRange(uint8_t start, uint8_t end, unsigned long delayTime=MIN_BLINK_TIME); //min delay is 1/2 second

Precompilers and other publicly available variables

#define CATHODE 0
#define ANODE 1
#define MIN_BLINK_TIME 500

class led7Segment {
public:
  bool nothing[8] = {0, 0, 0, 0, 0, 0, 0, 0}; // could be used to turn of or display nothing on the 7 segment display
};

Testing

The code and its usage has been tested using Proteus simulation software
