Python's lovely asyncio library allows me to write event-driven programs in a style that looks much like multithreaded code but isn't. Combining asyncio with the equally lovely Linux GPIO subsystem is just another logical step. In this talk I show what asyncio is, how libgpiod works, and how both are used to do pointless projects.
Continuing the story of pointlessly blinking lights from my last year's talk, I show
- How GPIO interrupts are configured to get notified of hardware button presses, and how this can look like in Python (hint: generators, and iteration).
- How button-events can be used in an
async
programming style (hint: asyncronous generators, andasync for
). - How this fits into the pointless project of blinking lights.
Additionally, I give an overview of async libraries that are more to the point, like
- Textual, a terminal UI framework
- python-sdbus, the Python binding for the systemd D-Bus client implementation
