| Supported Targets | ESP32-P4 | | ----------------- | -------- | # Camera display via DSI example ## Overview This example demonstrates how to use the esp_driver_cam component to capture camera sensor signals and display it via DSI interface. ## Usage The subsections below give only absolutely necessary information. For full steps to configure ESP-IDF and use it to build and run projects, see [ESP-IDF Getting Started](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html#get-started). ### Hardware Required This example requires: - OV5647 camera sensor - ILI9881C LCD screen - ESP32P4 devkit GND GND ┌────────────────────────────────────────────────┐ ┌─────────────────────────────────────────────────────────┐ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ ┌───────────────┴─────────────┴──────────────────┐ │ │ │ │ ┌──────────┴───────────┐ │ │ │ DSI DATA 1P │ │ │ │ ├───────────────────────────┤ │ ┌───────────┴─────────┐ CSI DATA 1P │ │ │ │ │ ├──────────────────────┤ │ DSI DATA 1N │ │ │ │ │ ├───────────────────────────┤ │ │ │ CSI DATA 1N │ ESP32-P4 │ │ │ │ OV5647 ├──────────────────────┤ │ DSI CLK N │ ILI9881C │ │ │ │ ├───────────────────────────┤ │ │ │ CSI CLK N │ │ │ │ │ ├──────────────────────┤ │ DSI CLK P │ │ │ │ │ ├───────────────────────────┤ │ │ │ CSI CLK P │ │ │ │ │ ├──────────────────────┤ │ DSI DATA 0P │ │ │ │ │ ├───────────────────────────┤ │ │ │ CSI DATA 0P │ │ │ │ │ ├──────────────────────┤ │ DSI DATA 0N │ │ │ │ │ ├───────────────────────────┤ │ │ │ CSI DATA 0N │ │ │ │ │ ├──────────────────────┤ │ └──────────────────────┘ │ │ │ │ └───────┬──┬──────────┘ │ │ │ │ I2C SCL │ │ │ └─────────────────────────────────┤ │ │ I2C SDA │ │ └────────────────────────────────────┤ │ └────────────────────────────────────────────────┘ ### Set Chip Target First of all, your target must be supported by both: - **By your ESP-IDF version**: For the full list of supported targets, run: ``` idf.py --list-targets ``` - **By this example**: For the full list of supported targets, refer to the supported targets table at the top of this README. After you make sure that your target is supported, go to your example project directory and [set the chip target](https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/tools/idf-py.html#select-the-target-chip-set-target): ``` idf.py set-target ``` For example, to set esp32-P4 as the chip target, run: ``` idf.py set-target esp32p4 ``` ### Configure the Project For information about Kconfig options, see [Project Configuration](https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/kconfig.html) > _Name of relevant section(s)_. To conveniently check or modify Kconfig options for this example in a project configuration menu, run: ``` idf.py menuconfig ``` ``` Set CONFIG_CAMERA_OV5647 to y ``` ### Build and Flash Execute the following command to build the project, flash it to your development board, and run the monitor tool to view the serial output: ``` idf.py build flash monitor ``` This command can be reduced to `idf.py flash monitor`. If the above command fails, check the log on the serial monitor which usually provides information on the possible cause of the issue. To exit the serial monitor, use `Ctrl` + `]`. ## Example Output If you see the following console output, your example should be running correctly: ``` I (1085) main_task: Calling app_main() I (1095) ili9881c: ID1: 0x98, ID2: 0x81, ID3: 0x5c I (1125) gpio: GPIO[31]| InputEn: 1| OutputEn: 1| OpenDrain: 1| Pullup: 1| Pulldown: 0| Intr:0 I (1125) gpio: GPIO[34]| InputEn: 1| OutputEn: 1| OpenDrain: 1| Pullup: 1| Pulldown: 0| Intr:0 I (1295) ov5647: Detected Camera sensor PID=0x5647 with index 0 I (1305) cam_dsi: fmt[0].name:MIPI_2lane_24Minput_RAW8_800x1280_50fps I (1305) cam_dsi: fmt[1].name:MIPI_2lane_24Minput_RAW8_800x640_50fps I (1315) cam_dsi: fmt[2].name:MIPI_2lane_24Minput_RAW8_800x800_50fps I (1355) cam_dsi: Format in use:MIPI_2lane_24Minput_RAW8_800x640_50fps ``` ## Reference - Link to the ESP-IDF feature's API reference, for example [ESP-IDF: Camera Controller Driver](https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/camera_driver.html) - [ESP-IDF Getting Started](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html#get-started) - [Project Configuration](https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/kconfig.html) (Kconfig Options)
