2.12 Camera header
The FRDM-MCXN947 provides a header for the camera connection. This is to demonstrate the camera
interface features of the MCXN947 device.
Note: The FRDM-MCXN947 board is tested with the OV7670 camera.
Note:
To use the camera, three solder jumpers SJ16, SJ26, and SJ27 must be moved over from their default
positions. This change avoids issues with reading in camera data correctly. However, this change disables
Ethernet functionality. If Ethernet functionality is still desired while using the camera, an alternative workaround
is to move the SJ16 and SJ26 jumpers from their default position. Then, connect a wire from P1_4 (on J9 pin 8)
to the left side of the R58 resistor.
Table 24 describes the camera header (J9) pinout.
