[camera web server example] FreeRTOS.h build error w/ Xiao ESP32C3

[mbz4]

Describe the bug Trouble building camera web server example - missing library reference: FreeRTOS.h Not sure which FreeRTOS.h to use, there's so many and its very configurable.

Observations:

• Suspect the C3 might be missing a (Seeed) FreeRTOS.h support package.
• The C3 may not have sufficient RAM for this example.
  • Would the Xiao ESP32-S3 Sense work better in its place (w/ Grove Vision Module v2)?

To Reproduce Hardware: Xiao ESP32C3 + Grove Vision Module v2

Steps to reproduce the behavior:

1. Configure project w/ PlatformIO or ArduinoIDEv2
2. Run Build / Compile Web Camera Server example project

Expected behavior Expected successful build, build errors instead.

Updates:

• Concluded C3 not supported
  • Need S3 instead
• assume the camera web server example deploys to the xiao not grove
• not sure what to deploy to the vision module
• vision module v2 wiki shows WIP on image collection script:
  • https://wiki.seeedstudio.com/grove_vision_ai_v2_sscma/ ...

We highly recommend that you use Grove Vision AI V2 to take pictures of your dataset, which is best for Grove Vision AI V2. Grove Vision AI V2 is currently developing the functionality part of taking pictures, and once that is done, you can use Grove Vision AI V2 to capture pictures for your dataset. Until then, you can use photos taken by other devices as datasets.

Figured to try collect the images using the xiao x vision module combo with this camera server example. Will try deploying and get this example running again. Ultimately just need the image dataset...

updates:

• build error does not repeat with xiao esp32s3
  • uploads successfully but stuck in reboot loop if having serial console open
  • browser page not loading

Hi guys,

I'm able to build camera webserver example for xiao esp32 c3 after commenting out the #include line in app_httpd.cpp.
