:Artifact: ``com.onyx.android.sdk:onyxsdk-device:1.2.31``
:Root package: ``com.onyx.android.sdk.api.device``
:Last release: February 2026

Low-level EPD hardware control. Waveform selection, partial and full screen
refreshes, display-hold freezing, front-light brightness, and coordinate
mapping between screen space and the digitizer's native space.

Most classes in this module are **hidden APIs** and require the
``hiddenapibypass`` library to be initialised in ``Application.attachBaseContext``
before any class is loaded — see :ref:`hidden-api-bypass`.
