An Arduino library for 7-segment display modules based on the TM1637 chip, such as Seeed Studio's Grove 4 digit display. The TM1637 chip also has keyboard input capability, but it's not implemented in this library.
The display modules has two signal connection (and two power connections) which are CLK and DIO. These pins can be connected to any pair of digital pins on the Arduino. When an object is created, the pins should be configured. There is no limitation on the number of instances used concurrently (as long as each instance has a pin pair of its own)
The library is installed as any Arduino library, by copying the files into a directory on the library search path of the Arduino IDE
The library provides a single class named TM1637Display. An instance of this class provides the following functions:
•setSegments - Set the raw value of the segments of each digit
•showNumberDec - Display a decimal number
•showNumberDecEx - Display a decimal number with decimal points or colon
•setBrightness - Sets the brightness of the display
The information given above is only a summary. Please refer to TM1637Display.h for more information. An example is included, demonstrating the operation of most of the functions.
15 de sept. de 2019 · En este tutorial, aprenderás cómo puedes controlar los displays de 7 segmentos de 4 dígitos TM1637 con Arduino. Estos displays son fantásticos para mostrar datos de sensores, temperatura, tiempo, etc. He incluido 3 ejemplos en este tutorial. En el primer ejemplo, veremos las funciones básicas de la librería TM1637Display.
TM1637 Driver. Display. Feature-full and simple TM1637 library with nonblocking animation support Features: -Display integers, float, string with only one function.
This library uses the LCD API v1.0 so you can use the same functions/methods using this library as any lcd library which conforms to the LCD API. Furthermore this library (like described in the LCD API) inherent the Print class (See Serial.print() and for more details Print.h).
The segment data //! is given as a byte array, each byte corresponding to a single digit. Within each byte, //! bit 0 is segment A, bit 1 is segment B etc. //! The function may either set the entire display or any desirable part on its own. The first //! digit is given by the @ref pos argument with 0 being the leftmost digit.
