add esp32-camera This uses the esp32-camera code instead of our own homebrewed camera code. In theory it supports esp32, esp32-s2 and esp32-s3, as long as they have PSRAM. This is very basic and doesn't support changing any camera parameters, including switching resolution or pixelformat. This is tested on the Kaluga (ESP32-S2) and ESP32-S3-Eye boards. First, reserve some PSRAM by putting this line in `CIRCUITPY/_env`: ``` CIRCUITPY_RESERVED_PSRAM=524288 ``` and hard-reset the board for it to take effect. Now, the following script will take a very low-resolution jpeg file and print it in the REPL in escape coded form: ```python import board import esp32_camera c = esp32_camera.Camera( data_pins=board.CAMERA_DATA, external_clock_pin=board.CAMERA_XCLK, pixel_clock_pin=board.CAMERA_PCLK, vsync_pin=board.CAMERA_VSYNC, href_pin=board.CAMERA_HREF, pixel_format=esp32_camera.PixelFormat.JPEG, i2c=board.I2C(), external_clock_frequency=20_000_000) m = c.take() if m is not None: print(bytes(m)) ``` Then on desktop open a python repl and run something like ```python >>> with open("my.jpg", "wb") as f: f.write(<BIG PASTE FROM REPL>) ``` and open my.jpg in a viewer.
