Control LCD display tm1637 from a raspberry pi

Original work from https://github.com/thesadabc/raspberrypi-tm1637-4display

You can control a LCD tm1637 with facultative semi-colon separator

Allowed characters : [aA-zZ],[0-9], ,°,-,=,[,],(,)

Dependencies

You need WiringPi library installed on your raspberry pi.

    sudo apt-get install python-dev python-pip
    sudo pip install wiringpi

Installation

Then install this module that way:

    npm install raspberrypi-tm1637

Usage

Warning !! Using WIRINNGPI pin numerotation ! Please see : https://fr.pinout.xyz/pinout/wiringpi#

    const TM1637 = require('raspberrypi-tm1637');
    const CLKPIN = 29;
    const DIOPIN = 28;
    const tm = new TM1637(CLKPIN, DIOPIN);

    // 4 characters max. Extra characters will be ignored

    tm.text="helo";     // Shows "helo"

    tm.text="2130";     // Shows "21:30"
    tm.split=true;      //

    tm.text="foo";      //
    tm.alignLeft=false; // Shows " foo"
    tm.alignLeft=true;  // Shows "foo "

API

Methods

• constructor(pinClk, pinDIO)
  • pinClk : int. The clock pin number using WIRINGPI pin numerotation
  • pinDIO : int. The data pin number using WIRINGPI pin numerotation

Properties

• text : string. Four characters max. Extra chars will be ignored.
• split : boolean. Default false. Will display the semi-colon separator based on that value. (good for clock or time usage)
• alignLeft : boolean. Default false. Will align the text, if less than four characters, on the left if true, on the right if false.
