WS2812 7-Segment Display V 1.1.0

Library to create a 7-Segment Display using WS2811b addressable LEDs

Developed and tested on MicroPython ( ESP8266 and ESP32 TTGO)

For bugs and ideas of improvement feel free to open an issue!

---

Changelog:

Version 1.1.0:

• It is now pissible to create multiple instances of the Segment Display on different pins of the controller
• (minor bugfixes)

Version 1.0.0

• Initial publish

---

Dependant libraries:

• micropython builtin libraries

Example of usage:

Controll a 2x2 7-Segment display with dots

---

1. Initiate the Display object by instantiating the Segments class

import segments
display = segments.Segments(NP_PIN, addrOfset=0, ledPerSegment=3, ledPerDot=1, numDisplay=4)

NP_PIN [int] is the pin-number the addressable LEDs are connected to

addrOffset [int] is the address of the first led of the display (normally 0 if u have no other leds in front on the data-line)

ledPerSegment [int] is the total count of LEDs in one single segment (default is 3 LEDs per segment)

ledPerDot [int] is the count of LEDs in a single Dot (default is 1 LED per dot)

numDisplay [int] is the count of single digit 7-segment-displays available for use (default is 4 displays)

2. Set the display to show your data

There are two different ways of showing your data on the Displays:

1. By writing each single digit display on its own:

   setSegment(num, value, color=(0, 0, 100))

   num [int] is the index of the digit you wanna set

   value [int/char] the value you want the display to be set to.

   color [tuple (R, G, B)] the color you want the value to be displayed (Default: 0, 0, 100 --> Blue)

2. By writing each double segment

   setDoubleSegment(self, num, value, color=(0, 0, 100))

   num [int] is the index of the digit you wanna set

   value [int/char] the value you want the display to be set to. ¹

   color [tuple (R, G, B)] the color you want the value to be displayed (Default: 0, 0, 100 --> Blue)

3. By switching the dots

   setDots(display, dotColor=(0, 0, 100))

   display [bool] is the parameter if the dots should be on (True) or off (False)

   dotColor [tuple (R, G, B)] is the color the dot schould be displayed
