v1.12.0 - Clear Display Option

What's Changed

• Update begin() function to allow parameter control of display clear and full brightness setting. Default behavior if not specified will be true which is the behavior with prior version.
• Remove clean and set brightness from begin by @smaryus in #42.

//! Initialize the display, setting the clock and data pins.
//!
//! This method should be called once (typically in setup()) before calling any other.
//! @note It may be unnecessary depending on your hardware configuration.
void begin();
//! @param clearDisplay - Clear display and set the brightness to maximum value.
void begin(bool clearDisplay=true);

void TM1637TinyDisplay::begin(bool clearDisplay)
{
  // Set the pin direction and default value.
  // Both pins are set as inputs, allowing the pull-up resistors to pull them up
  pinMode(m_pinClk, INPUT);
  pinMode(m_pinDIO, INPUT);
  digitalWrite(m_pinClk, LOW);
  digitalWrite(m_pinDIO, LOW);
  if (clearDisplay)
  {
    clear();
    setBrightness(BRIGHT_HIGH);
  }
}

v1.10.0 - Animation Looping

What's Changed

• Bug Fix: Changed abs() to long int supported labs() in showNumber() method by @KelevraSlevin7 in #33 which fixes overflow situation seen on some cores for showNumber()
• Added option for non-blocking animation to allow looping sequence via Animate(true) and added method to stop animation with stopAnimation() for TM1637TinyDisplay and TM1637TinyDisplay6 classes.

  //! The event loop function to enable non-blocking animations
  //!
  //! The method returns TRUE when an animation is still occurring, it is
  //! FALSE when there is no animation occurring
  //!
  //! @return A boolean value indicating if an animation is occurring
  //! @param loop If true, keep looping animation when it ends
  bool Animate(bool loop = false);

  //! The function used to stop a non-blocking animation
  //!
  void stopAnimation();

v1.9.0 - Add Non-Blocking Animation for 6-Digit

What's Changed

• Add non-blocking animation support to 6 digit displays by @hackerceo in #31

Full Changelog: v1.8.1...v1.9.0

v1.8.1 - Add Default Brightness

What's Changed

• Updated the begin() method to set a non zero default brightness for the display, as suggested in #29 (comment) and submitted by @mgesteiro in #30

Full Changelog: v1.8.0...v1.8.1

v1.8.0 - Add begin() for Initialization

What's Changed

• Updated library operation to include an initializing method begin() to move hardware related calls outside the class constructor, as reported in #28 and submitted by @mgesteiro in PR #29

Example Best Practice

#include <TM1637TinyDisplay.h>

TM1637TinyDisplay display(CLK, DIO);  // Instantiate TM1637TinyDisplay Class

void setup() {
  display.begin();   // Initialize Display
  display.setBrightness(BRIGHT_HIGH);
}

void loop() {
  display.showString("HELLO");
  delay(500);
}

Bug Fix for showNumber Negative Numbers

v1.5.2

• Fix showNumber() but for negative numbers. Solves issues #17 (thanks to @otpfiste).
• Fix showNumber() overflow condition for numbers (positive and negative) that do not fit within display length.

  // Example of negative case that did not render correctly
  display.showNumber(-3.1, 1, 3, 1);  // (float num, decimal length, length, position)

  // Overflow Examples - will render a dash display e.g. "----" 
  display.showNumber(-1000);
  display.showNumber(10000000);
  display.showNumber(-333.1, 1, 3, 1);
