Digital pins: drive, read, and count a pin's pulses by interrupt, plus a boot step that drives a pin. The platform package supplies the backend

settleMs	int32	0	0 to 5000	Milliseconds to wait afterwards, for a power rail to come up before the next setup step

Changelog

0.19.0 Changed

minEngine 0.19.0: built against engine 0.19.0, whose component metadata records the package each class is in. A build of this package from before does not load and is rebuilt.

Added

Japanese, Simplified Chinese and Korean: editor/lang/ja.json, zh.json and ko.json translate the names, tooltips and enum values this package's components show in the Inspector.

0.18.0 Changed

minEngine 0.18.0. Reflection ABI 21: the package must be rebuilt.
Names follow the code style (deki-engine/docs/codestyle): types, functions and enum values are PascalCase, constants kPascalCase, members m_PascalCase, locals and parameters camelCase. The code is formatted with clang-format 22.
The functions the editor finds by name are PascalCase: DekiGPIORegisterComponents, DekiGPIOGetAutoComponentCount, DekiGPIOEnsureRegistered and the rest. Built against engine ABI 21; a build of this package from before does not load and is rebuilt.

Removed

The former names from before 0.16.0 (bare class names, and deki-gpio's DekiEsp32::ESP32PinSetup). A scene that old is upgraded with 0.17 first.

Earlier releases: CHANGELOG.md.

Generated from the package's reflection data (engine 0.19.0). Property names are the keys used in scene files. Renames keep an alias (compatibility).
