pub unsafe extern "C" fn QTMC_StartHardwareCheck() -> ResultExpand description
Starts the QTM Hardware Check API. This must be called before using any other qtm:c command,
and causes barrier pattern to be overriden by what was last set in QTMC_SetBarrierPattern,
even in 2D mode. Also allows IR LED state to be overridden even if user uses the inner camera.
