Using Zero cost meta-framework for IOT
Zero-cost abstractions for pin frameworks
This project is in early development and should only be used by contributing developers. Expect substantial changes to the library API as it evolves. Contributions, ideas and PRs are very welcome.
Provide a set of common small libraries packed into one.
Serve as an example of OnePin library usage.
-
Button simple button state provider with states:
- Open⁺
- Pressed
- Hold⁺
- Released
⁺ Open and Hold states can repeat
Pressed and Released states are unique and must be consumed
-
ClickButton Button variant with extra unique states:
- DoubleClicked
- Clicked
-
Encoder simple quad-encoder driver
-
AccelEncoder Encoder variant with acceleration
