How to integrate USER_C_MODULES into this project

[hcwang]

I would like to integrate https://github.com/cnadler86/micropython-camera-API into this project, but I don't know how to do this. Would you please help me? Thanks.

1. how to add components into ESP-IDF?

Setting up the build environment (DIY method)

To build the project, follow these instructions:

ESP-IDF: I used version 5.2.3, but it might work with other versions (see notes).
Clone the micropython repo and this repo in a folder, e.g. "MyESPCam". MicroPython version 1.24 or higher is required (at least commit 92484d8).
You will have to add the ESP32-Camera driver (I used v2.0.15). To do this, add the following to the respective idf_component.yml file (e.g. in micropython/ports/esp32/main_esp32s3/idf_component.yml):
espressif/esp32-camera:
git: https://github.com/espressif/esp32-camera.git
Alternatively, you can clone the https://github.com/espressif/esp32-camera repository inside the esp-idf/components folder instead of altering the idf_component.yml file.

2. How to add camera configurations to your board ?

This project supports various boards with camera interface out of the box. You typically only need to add a single line to your board config file ("mpconfigboard.h). Example (don't forget to add the empty line at the bottom):

#define MICROPY_CAMERA_MODEL_WROVER_KIT 1`

3. How to build the project with USER_C_MODULES?

To build the project, you could do it the following way:

. /esp-idf/export.sh
cd MyESPCam/micropython/ports/esp32
make USER_C_MODULES=../../../../micropython-camera-API/src/micropython.cmake BOARD=<Your-Board> clean
make USER_C_MODULES=../../../../micropython-camera-API/src/micropython.cmake BOARD=<Your-Board> submodules
make USER_C_MODULES=../../../../micropython-camera-API/src/micropython.cmake BOARD=<Your-Board> all

Thanks for your help, and your project make my life easier, thanks.
