MP camera for esp32-s3

[shariltumin]

Those interested in the esp32-s3 firmware with camera module can have a look here.

Currently three ESP32-S3 camera boards are supported.

LILYGO-T-Camera-OV2640 N16R8 (Flash 16MB, PSRAM 8MB)
XIAO-Sense-OV2640 N8R8 (Flash 8MB, PSRAM 8MB)
Freenove-OV2640 N8R8 (Flash 8MB, PSRAM 8MB)

Thanks for those. Out of curiosity, I tried the LILYGO-T-Camera-OV2640 firmware with a Lilygo T-SIMCAM. While it did produce a REPL, unsurprisingly the camera didn't work

# Lilygo T-SIMCAM Board (12Mhz ???)
t_simcam =    {PIN_PWDN:-1, 
              PIN_RESET:18,
              PIN_XCLK:14, 
              PIN_SIOD:4,
              PIN_SIOC:5,
              PIN_D7:15,
              PIN_D6:16,
              PIN_D5:17,
              PIN_D4:12,
              PIN_D3:10, 
              PIN_D2:8, 
              PIN_D1:9, 
              PIN_D0:11,  
              PIN_VSYNC:6,
              PIN_HREF:7,
              PIN_PCLK:13,
              XCLK_MHZ:12, # not sure what speed
              PIXFORMAT:5,
              FRAMESIZE:10,
              JPEG_QUALITY:10,
              FB_COUNT:1,
} 

Please try adding the above settings to the "cam_config.py" file. These values are from the link you provided.

The "cam_config.py" file can be found at https://github.com/shariltumin/esp32-cam-micropython-2022/blob/main/Christmas-2023-Edition/scripts/cam_config.py

Then try this init script:

import camera
import cam_config as cc

# set camera configuration
cc.configure(camera, cc.t_simcam)
camera.init()

Hopefully this will work.

that did it, thanks!

I bought a cheap ESP32-S3 board with CAM interface, SD card slot (labeled "127294G_Y1127_231016" on the back side) from AliExpress
with OV5640 cam that looks like the Freenove board. First I tried @shariltumin firmware but got no REPL. Then I tried GENERIC ESP32-S3 Micropython firmware ESP32_GENERIC_S3-SPIRAM_OCT-20240222-v1.22.2.bin with working REPL. Any idea why Freenove firmware does not work?

[shariltumin]

Sorry to hear that. The firmware only supports OV2640.

$ tio /dev/ttyACM0
[tio 14:09:47] tio v1.32
[tio 14:09:47] Press ctrl-t q to quit
[tio 14:09:55] Connected

>>>
>>> import machine
>>> machine.reset()

[tio 13:52:14] Disconnected
[tio 13:52:15] Connected

>>>
MPY: soft reboot
MicroPython v1.20.0-206-g33b403dfb-kaki5 on 2024-01-17; ESP32S3-FREENOVE OV2640 (KAKI5) with ESP32-S3
>>> import camera
>>> camera.init()
True

You should get the REPL. Which of the two USB ports you tried? To get to the REPL I connect to the USB-OTG port. Press ENTER a few times to get the prompt.

[rena2019]

My fault...I forgot to erase flash before writing the firmware file. Now I get the REPL:

MicroPython v1.20.0-206-g33b403dfb-kaki5 on 2023-07-10; ESP32S3-FREENOVE OV2640 w/BLE (KAKI5) with ESP32-S3
>>> import camera
>>> camera.init()
False

But how it is possible to configure the OV5640 camera? Or do I have to build a custom Micropython ? @shariltumin where can I find the latest source for the cam module?

How cool! timing is exciting, I've just been working on an spi only camera ArduMega SPI camera as I've been a bit intimidate by the pin outs. At least this version, just got it taking pictures last night, working with cameras is quite fun! https://github.com/stephanelsmith/ArducamMega-micropython

Your project seems to be a better way to go, I'm a bit concerned about size/weight for my eventual application. I will see if I can pick up some of the hardware and try it out.

Thank you for sharing your project. Looking forward to checking it out!

You can get ESP32-Cam with downloader module for US$6.00 from AliExpress.
