How to wire

The module has 10 pins. 7 of them are for each segment of the display module. One is for the decimal point, and two are common ground.

Each pin should be connected to a valid GPIO pin, and you should put a 330 ohm resistor between each LED. This means you will have 8 LEDs.

You can’t just place a single resistor for all the LEDs. If you do this, you’ll get varying brightness depending on how many segments are illuminated.

Using the driver

Instantiate the driver using the static make() function, passing a reference to each pin.

use DanJohnson95\Pinout\Facades\PinService;
use DanJohnson95\Pinout\Drivers\SevenSegmentDisplay;

$driver = SevenSegmentDisplay::make(
    pinA: PinService::pin(13),
    pinB: PinService::pin(14),
    pinC: PinService::pin(15),
    pinD: PinService::pin(16),
    pinE: PinService::pin(17),
    pinF: PinService::pin(18),
    pinG: PinService::pin(19),
    pinDP: PinService::pin(20)
);

You can call the following methods on the driver:
