An hidapi based driver for direct interaction with Elgato StreamDeck devices, this is intended to allow applications to use these devices directly and on arbitrary platforms (without the use of the Elgato SDK), heavily based on the python streamdeck library.

WIP. Pull requests more than welcome!

Features:

• Connecting to devices
  • Connecting by VID/PID/Serial
  • Matching device types (Mini etc.)
• Reading buttons
  • Poll based mode (w/ blocking / non-blocking selection and timeouts)
  • Multi-threaded / async / callback driven mode
• Writing brightness
• Setting buttons
  • Writing colours
  • Writing images
• Devices
  • Stream Deck Mini
  • Stream Deck Original (untested)
  • Stream Deck Original V2
  • Stream Deck XL

• cargo add streamdeck to add this library to your project (with cargo-edit)
• cargo install streamdeck to install the utility only
• git clone [email protected]:ryankurte/rust-streamdeck.git to clone the repo

Building requires libusb and hidapi packages.

• cp 40-streamdeck.rules /etc/udev/rules.d/ to allow user access to streamdeck devices
  • note this may need to be edited with other vid/pid combinations for other devices
• sudo udevadm control --reload-rules to reload udev rules

streamdeck-cli --help displays available subcommands and options, passing --help to subcommands (ie. streamdeck set-image --help) displays options for that subcommand
