Robot 7-segment Display, v1.0.0

The library for controlling a 7-segment display.

Major version. Implementing controlling one display.

Features

• possibilities:
  • controlling one display;
• structures:
  • the Character structure represents a character and keeps a set of specific segments that should be active for displaying this character;
  • the Display structure represents one display and keeps mapping between segments and pins to which they are connected.

Examples

A one-display stopwatch:

#include <Character.h>
#include <Display.h>
#include <PinForSegment.h>

using namespace irenica_ideas::robot_7_segment_display;

constexpr auto ONE_DIGIT_DELAY_IN_MS = 1000;

const Character digits[] = {
  Character(0x7e), // digit 0
  Character(0x30), // digit 1
  Character(0x6d), // digit 2
  Character(0x79), // digit 3
  Character(0x33), // digit 4
  Character(0x5b), // digit 5
  Character(0x5f), // digit 6
  Character(0x70), // digit 7
  Character(0x7f), // digit 8
  Character(0x7b)  // digit 9
};

// TODO: specify your own pin for every segment.
auto display = Display(
  PinForSegment<'a'>{2},
  PinForSegment<'b'>{3},
  PinForSegment<'c'>{5},
  PinForSegment<'d'>{7},
  PinForSegment<'e'>{11},
  PinForSegment<'f'>{13},
  PinForSegment<'g'>{17},
  PinForSegment<'p'>{19}
);

void setup() {
  display.initialize();
}

void loop() {
  for (const auto& digit: digits) {
    digit.show(display);
    delay(ONE_DIGIT_DELAY_IN_MS);
  }
}
