This is the Repo for the Core Electronics port of the Arducam Mega Cameras for the Raspberry Pi Pico (Micropython)
Status: Experimental This driver is very much experimental at the moment. Expect frequent, breaking updates. This project is featured in the 27-July-2023 episode of The Factory - Core Electronics' Engineering and Product Development vlog.
Thank you to @chrisrothwell1 for getting burst reads working - significantly removing the same time for each image (#9)
Thank you to @wil-liammacleod for adding debug mode, a pin reference for the ESP32-S3 and testing on MicroPython 1.24 (#11)
Project Status:
- Confirmed working on 3MP Camera and 5MP Camera
- SOLVED: Photos have a green hue, camera_idx identifies the two versions - https://forum.arducam.com/t/mega-3mp-micropython-driver/5708
- Can set resolution
- Can set remaining filters and modes
- Able to set multiple adjustments at the same time (see issue#3)
- Class moved to separate file
- Burst read - decrease time to save photo
- Set SPI Speed higher - decrease time to save photo - Recommended speed from ArduCam 800000 baud, need to implement a check on init
- Confirm a micro SD card can use the same SPI bus (Micropython compatibility) - requires camera to release SPI bus, bulk reading/writing into bytearray would speed this up
- Confirm working with the latest Micropython version - Version 1.24 tested
- Filemanager also handles subfolders for images - Requires examples
- Confirm that different file formats output correctly (RGB=BMP, YGV?)
- Confirm that pixel RGB values can be extrapolated from BMP format for machine learning applications
Camera(spi_bus=, cs=, skip_sleep=False, debug_text_enabled=False)
The Cameras initialisation method.
| Parameter | Type | Range | Default | Description |
|---|---|---|---|---|
| spi_bus | SPI | Device dependent | N/A | The SPI Bus the camera is connected to. |
| cs | Pin | Device dependent | N/A | The Pin the CS wire is connected to. |
| skip_sleep | Boolean | True, False | False | Skips the auto-white-balance on the 5MP Mega |
| debug_text_enabled | Boolean | True, False | False | If enabled, prints the status of the camera |
Camera.capture_jpg()
Capture a JPG photo with the provided settings.
Camera.save_JPG(filename, progress_bar=True)
Requires Camera.capture_jpg() to be run first, saves the JPG to the filename provided (it should include the filetype extension .jpg.
Note: This function can over-write other photos, we recommend using the filemanager.
| Parameter | Type | Range | Default | Description |
|---|---|---|---|---|
| filename | str | N/A | 'image.jpg' | The file path for the image. |
| progress_bar | Boolean | True, False | True | Prints a progress bar as the image saves. |
