Autofocus interface The camera supports one-shot autofocus and continuous autofocus modes. The Dev Board's sysfs node for the autofocus hardware is at /sys/module/ov5645_camera_mipi_v2/parameters/ov5645_af and it reads back the decimal representation of the status register in the autofocus hardware. The read values are as follows. Table 2. Autofocus read values from sysfs node Read value Description 0 (0x00) Autofocus is running. 16 (0x10) Autofocus is complete (focused).
Camera adapter We designed a simple camera adapter board to interface the camera with the Dev Board, as illustrated in figure 2. Figure 2. Camera adapter card diagram The MIPI-CSI2 camera connector is a 24-pin flex cable connector that's designed for the Coral Camera. The pinouts for the camera's cable connector (on the camera module), are shown in table 4. Whereas the corresponding pins on the Dev Board's connector are shown in table 5.

When using this interactive mode, each time you press Spacebar, it saves the image to the current directory as a JPEG. The filename includes an incrementing number, starting with img0000.jpg. Overwritting filenames is avoided by always starting with the first available enumeration of the filename. The command also accepts the following arguments: Table 7.
