Will there be a guide released on how to utilize the auto-focus feature on the OV5640 module?

[xzxcessarr]

Hello, the flash bin of the module we provide include the auto-focus feature, so there is no more step for you to set.

If you found any problem occur, please tell us, thanks for your feedback!

Is there a way I can use this board as a webcam or a wired camera by connecting it to my laptop?

[23Neo23]

can i use the sense and the camera to webstream using circutpython

[haya-sann]

i tried https://github.com/limengdu/SeeedStudio-XIAO-ESP32S3-Sense-camera/tree/main/CameraWebServer .
However, the Arduino IDE gave the following compiler error.
Do you have any advice on how to fix it?

/XIAO_ESP32S3/CameraWebServer/app_httpd.cpp: In function 'void setupLedFlash(int)':
/XIAO_ESP32S3/CameraWebServer/app_httpd.cpp:1389:5: error: 'ledcSetup' was not declared in this scope; did you mean 'ledc_stop'?
 1389 |     ledcSetup(LED_LEDC_CHANNEL, 5000, 8);
      |     ^~~~~~~~~
      |     ledc_stop

exit status 1

[aDW-code]

Hi, I researched the error message you provided and found a similar issue discussed in this forum topic. It seems the issue stems from a change in the ESP32 core version, as the old API was removed. This reference document provides more details on the changes. You might be able to resolve the error by updating your code according to the compiler's suggestions.

How do we tell which version of ESP32S3 Sense or the Camera module is in my possession? Version 2 or version 3?

[gesGitHub]

I have v1.0 of the camera module but how to tell which version of ESP32S3 Sense I have?

Hi, I have been trying so hard to make my own camerawebser program, but I have had complications with my code, the camera and the web server do not work and apparently a watchdog is activated in the program, displaying the same messages on the serial port.

That is Generic ONVIF and RTSP support for legacy camera connection?

[nfs0619]

Thank you for your feedback! Currently, we support OV5640 and OV2640 cameras, and we've made some modifications to this library to enable support. In principle, the ONVIF and RTSP support you mentioned can be implemented, but it will require some software modifications on your end to achieve this.

That being said, we highly recommend using the cameras we officially support for the best performance and compatibility. Feel free to try out the modifications and provide any further feedback — we'll continue to improve and enhance the support.

[skittleson]

For micropython with OV5640 cam, i had to flash it with the latest release from https://github.com/cnadler86/micropython-camera-API in releases section for this module. Here is github gist of an example sending it to a ntfy notification https://gist.github.com/skittleson/e869a039a01b66fb8add218053b663ef

[1Krosx1]

Is SX esp32 s3 support other 0V5460?

[nfs0619]

Hello, we recommend using the OV5640 camera that is recommended in the documentation together with the XIAO ESP32S3 Sense.
If you encounter any issues, please feel free to contact our technical support team at techsupport@seeed.io.

[albinea]

i have xiao esp32s3 sense with OV3660 sensor no matter what i do i cant get video streaming and capture image only the website is loading i cant get the image

[bleaaach]

Hi,
Please provide the relevant logs, and confirm whether you have configured the PSRAM according to our wiki. Please do not skip any steps.
Please flash a model on our SenseCraft AI platform to ensure that the camera functions properly on the hardware.

[1Krosx1]

i have Xiao and the reason why i want OV5640 is that it keeps shattering green pigment in the original camera.

Hi, could you please provide relevant screenshots so that we can analyze the issue? Was the problem present as soon as you received the product? Additionally, do you also get the same green screen when testing on our SenseCraft AI platform?

i used the product as soon as i got it i tested the camera module after a few days then i knew the thing was not working as screen shot what should i give u how to get the logs of this board i havent used sense craft ai i will try it and share what happens

i have an update when i change the pixel format to grayscale its working video streaming and capturing

[davefes]

In this tutorial you mention:
esp_err_t esp_camera_save_to_nvs(const char *key);
esp_err_t esp_camera_load_from_nvs(const char *key);
but I do not see them anywhere in source code. Could you point me to
the relevant information.

Thank you.

[nfs0619]

You can find the related functions in the following source files:

• https://github.com/espressif/arduino-esp32/blob/2.0.2/tools/sdk/esp32/include/esp32-camera/driver/include/esp_camera.h
• https://github.com/espressif/arduino-esp32/blob/caef4006af491130136b219c1205bdcf8f08bf2b/tools/sdk/esp32/include/esp32-camera/driver/include/esp_camera.h#L200

Hope this helps!

[davefes]

I have tried to use these functions and when I saw it mentioned in this tutorial I hoped to learn from your example. I meant I could not see those functions being used in your source code. I didn't see Preferences.h anywhere, so maybe you had used EEPROM to store some variables using those functions in the past.

Thank you.

I'm new to seeed studio products, I want to know if you also provide code for ESP-IDF?

[akhilgupta1002]

i want to read qr code with helop esp32s3 sense and want to display the content of qr on display .but issue is that no such library is present in arduino for reading the qr code.What should i do?
