TM1637

TM1637 Library Driver for Microcontrollers.

Features Supports displaying floating point numbers, integers, String Supports custom raw data display Tunable offset, pad, fill Supports animation: blink, left scroll, fade in and fadeout with custom delay Screen clearing, on/off mode, on/off colons Tunable brightness Example

Basic example:

#include // Instantiation and pins configurations // Pin 3 - > DIO // Pin 2 - > CLK TM1637 tm(2, 3); void setup() { tm.begin(); } void loop() { // Display Integers: tm.display(1234); delay(1000); // Display float: tm.display(29.65); delay(1000); // Display String: tm.display("PLAY"); delay(1000); tm.display("STOP"); delay(1000); } API class TM1637 { public: static constexpr uint8_t TOTAL_DIGITS = 4; TM1637(uint8_t clkPin, uint8_t dataPin) noexcept; TM1637(const TM1637&) = delete; TM1637& operator=(const TM1637&) = delete; ~TM1637() = default; void begin(); inline void init(); inline Animator* refresh(); template typename type_traits::enable_if< type_traits::is_string::value || type_traits::is_floating_point::value || type_traits::is_integral::value, Animator*>::type display(const T value, bool overflow = true, bool pad = false, uint8_t offset = 0); Animator* displayRawBytes(const uint8_t* buffer, size_t size); void offMode() const noexcept; void onMode() const noexcept; inline void colonOff() noexcept; inline void colonOn() noexcept; inline Animator* switchColon() noexcept; void clearScreen() noexcept; inline void setDp(uint8_t value) noexcept; inline uint8_t getBrightness() const noexcept; void changeBrightness(uint8_t value) noexcept; void setBrightness(uint8_t value) noexcept; }; class Animator { public: Animator(uint8_t clkPin, uint8_t dataPin, uint8_t totalDigits); void blink(Tasker::duration_type delay); void fadeOut(Tasker::duration_type delay); void fadeIn(Tasker::duration_type delay); void scrollLeft(Tasker::duration_type delay); void off() const; void on(DisplayControl_e brightness) const; void reset(const String& value); void clear(); void refresh(); } struct DisplayDigit { DisplayDigit& setA(); DisplayDigit& setB(); DisplayDigit& setC(); DisplayDigit& setD(); DisplayDigit& setE(); DisplayDigit& setF(); DisplayDigit& setG(); DisplayDigit& setDot(); operator uint8_t(); void operator=(uint8_t rhs); } Test

Tested on my Arduino Uno. Should work on every controller board that supports the Arduino platform.
