6.16 Camera
module
A connector CN4 for DCMI signals is on STM32F779I-EVAL evaluation board and camera
module daughterboard MB1183.
DCMI signals are duplicated with other peripherals (SAI, I
2
S, NOR Flash, microSD cards,
trace and MEMS microphone). These peripherals may not function correctly if camera
module is being used.
PC7 is shared between PAR_D1 of the camera and the EN pin of the NOR flash. As a
consequence when the camera is working, JP10 must be opened to avoid conflicts between
NOR Flash and camera.

Display and input devices
The 4-inch 800x480 TFT color LCD with capacitive touch panel is connected to MIPI DSI
interface of the STM32F779NI. Users can connect MB1232 to DSI LCD connector CN15, to
convert the DSI interface to the HDMI interface; users can also connect MB1233 to CN15 to
use RaspberryPI LCD.
Four general purpose color LEDs (LD1, 2, 3 and 4) are available as display devices and
they are connected respectively to PI15, PJ0, PJ1, and PJ3 of the STM32F779NI.
The 4-direction joystick (B3) is connected to the MFX.
User button (B2) is connected to PC13 which supports Wakeup or Tamper feature.
