CAMERA_I2CExposure*

Syntax

#include <twl/camera.h>

CAMERAResult CAMERA_I2CExposure(CAMERASelect camera, int exposure);
CAMERAResult CAMERA_I2CExposureAsync(CAMERASelect camera, int exposure, CAMERACallback callback, void *arg);

Arguments

camera Camera to configure (CAMERA_SELECT_IN, CAMERA_SELECT_OUT, or CAMERA_SELECT_BOTH).
exposure The amount of exposure to set.
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 configuration was successful.

Description

Sets the camera exposure (illumination time). The exposure argument must be specified between -5 and 5.

Unlike CAMERA_I2CExposure, the CAMERA_I2CExposureAsync function returns control immediately and runs asynchronously. Use callback to confirm that processing has completed.
