Generic Buttons
===============

[](#generic-buttons)

### Basic on/off GPIO buttons with PHP

[](#basic-onoff-gpio-buttons-with-php)

PHP package for simple digital buttons (momentary switches to GND or VCC). It sits on the ScrapyardIO GPIO stack and plugs into the BareMetal HumanInput components (`BasicButton`, `DigitalButtonPad`).

Compatible Digital Interfaces
=============================

[](#compatible-digital-interfaces)

Buttons are read from a digital input pin. Most switches to ground need an internal pull-up.

You can interface with them the following ways:

- A Linux single-board computer's exposed GPIO pins using the POSIX / libgpiod carrier (`posix`) with `LineBias::PULL_UP`
- An MPSSE-enabled USB-to-serial device such as an FT232H using the USB carrier (`usb`)

Dependencies
============

[](#dependencies)

This package makes use of modules within:

- [The ScrapyardIO Framework](https://github.com/ScrapyardIO/framework)

For GPIO buttons you also need:

- [POSI Extension v^0.4.0 or newer](https://github.com/php-io-extensions/posi)
- [Microscrap POSIX Drivers](https://github.com/microscrap/scrapyard-posix-drivers) (`posix` carrier)

Installing from Composer
========================
