CAMERA_I2CContextSwitch*

Syntax

#include <twl/camera.h>

CAMERAResult CAMERA_I2CContextSwitch(CAMERASelect camera, CAMERAContext context);
CAMERAResult CAMERA_I2CContextSwitchAsync(CAMERASelect camera, CAMERAContext context, CAMERACallback callback, void *arg);

Arguments

camera Camera to change the context for (CAMERA_SELECT_IN or CAMERA_SELECT_OUT).
context Context to change.
callback Function that is called when asynchronous processing has completed.
arg Arguments when the callback function is invoked.

Return Values

Returns CAMERA_RESULT_SUCCESS if changes were possible.

Description

Switches the camera settings context. It is faster to switch the context than to configure settings individually.

To switch the settings for the specified camera to the specified context (A or B), you cannot set camera to CAMERA_SELECT_NONE or context to CAMERA_CONTEXT_BOTH.

Unlike CAMERA_I2CContextSwitch, the CAMERA_I2CContextSwitchAsync function will return control immediately and run asynchronously. Use callback to confirm that processing has completed.
