WeAct Studio MiniSTM32H7xx OV2640 Camera Sensor

Overview

The OV2640 camera sensor is designed to interface with the WeAct Studio MiniSTM32H7xx boards, providing camera sensor capabilities. This shield integrates the OV2640 camera module, which is capable of capturing images and video with a resolution of up to 2 megapixels.

More information about the OV2640 camera sensor can be found on the MiniSTM32H7xx GitHub and in the OV2640 datasheet.

Requirements

Your board needs to have a zephyr_camera_dvp device tree label to work with this shield.

Programming

Set --shield weact_ov2640_cam_module when you invoke west build. For example:

# From the root of the zephyr repository
west build -b mini_stm32h743 --shield weact_ov2640_cam_module samples/drivers/video/capture_to_lvgl/ -- -DCONFIG_BOOT_DELAY=2000
