CAMERA_I2CFrameRate*

Syntax

#include <twl/camera.h>

CAMERAResult CAMERA_I2CFrameRate(CAMERASelect camera, CAMERAFrameRate rate);
CAMERAResult CAMERA_I2CFrameRateAsync(CAMERASelect camera, CAMERAFrameRate rate, CAMERACallback callback, void *arg);

Arguments

camera Camera to configure (CAMERA_SELECT_IN, CAMERA_SELECT_OUT, or CAMERA_SELECT_BOTH).
rate Frame rate.
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

Changes the camera's frame rate.

Unlike CAMERA_I2CFrameRate, the CAMERA_I2CFrameRateAsync function returns control immediately and runs asynchronously. Use callback to confirm that processing has completed.

Do not set CAMERA_FRAME_RATE_30_TO_5 or CAMERA_FRAME_RATE_30 with this function while either CAMERA_SIZE_VGA or CAMERA_SIZE_DS_LCDx4 is specified with the CAMERA_I2CSize* functions. You can no longer obtain capture data if these two settings are used at the same time.
