8.5 CN7 camera module connector
On the STM32H7B3I-DK board, a 30-pin CN7 connector with Digital Camera Interface DCMI signals is available
to connect an 8-bit camera module such as the STM32F4DIS-CAM module. This module must be connected with
caution before powering the STM32H7B3I-DK board.
Note:
The camera clock is the MCO clock by default. I
2
C address for the STM32F4DIS-CAM module is 60h and 61h.
Limitations:
Care must be taken of GPIO sharing and multiplexing with other functions, to program the good configuration.
GPIO assignment and sharing are precise below:
• DCMI_SDA and DCMI_SCL I
2
C peripheral are shared with the STMod+ and ARDUINO
®
connectors, audio
codec, and TFT LCD.
• Camera signals PA4, PB8, PB9, PC6, PC7, and PD3 are shared with the STMod+ connector.
• Camera signals PC9 and PC11 share with SDIO1_D1 and SDIO1_D3 signals
•
DCMI_HSYNC camera signal (PA4) is shared with the ARDUINO
®
ARD_A0 signal.
As a consequence, when using the camera, the user must pay attention that there is nothing connected to
STMod+ connector. And SB44 must be OFF. Same, when using the camera, the microSD
™
cannot be used.
At least, the user must take care that the SB45 is OFF (ARD_A0 signal disconnected to PA4).
