myGPIOd

myGPIOd is a lightweight GPIO controlling framework and hotkey daemon written in C.

It consists of a daemon with an integrated HTTP server, a client library and a command line tool. It is designed to run on Raspberry PIs and similar devices.

I wrote this tool primarily for myMPDos and myMPD.

You can use myGPIOd to execute various actions based on events emitted by GPIOs (/dev/gpiochip*), input devices (/dev/input/*), timers and hooks (webhooks and hooks initiated by a socket client).

Features

• mygpiod - the daemon component
  • Call actions on GPIO events
    • rising
    • falling
    • long press (with optional interval)
    • long press release
  • Call actions on input events (/dev/input/..)
  • Timer based events
  • Integrated actions
    • GPIO settings
    • HTTP requests
    • Lua scripting (synchronous and asynchronous)
    • MPD client
    • myMPD client
    • System commands
  • Set various GPIO attributes (bias, debounce, ...)
  • Set the output value of GPIOs
  • Get info from Raspberry PI Video Core (/dev/vcio)
  • Provides a Unix socket with a simple line-based text protocol
    • List GPIO configuration
    • Set and get GPIO values
    • Get notifications of GPIO events
  • Provides a REST-API endpoint
    • List GPIO configuration
    • Set and get GPIO values
  • Provides a long poll endpoint to receive GPIO and input events
• libmygpio - the client library
  • Simple C client library
  • High level API
  • Integration in poll based event loops
• mygpioc - the command line client
  • Connects to the mygpiod socket to control the various functions.
