ESP32 Camera - Image server

This tutorial explains how to setup a HTTP web server on a ESP32 to return to the client images taken by a camera connected to the microcontroller.

For a written tutorial with source code, please check the corresponding post on my blog: https://techtutorialsx.com/2020/06/10...

I'm using a HW-818 camera board model and a OV2640 camera. The board can be found at eBay: https://www.ebay.com/sch/i.html?_from...

We will make use of the async HTTP web server library: https://github.com/me-no-dev/ESPAsync...

For an introductory tutorial on how to use this server library, please check my other videos or my blog: https://techtutorialsx.com/2017/12/01...

Some corrections / additional information of what was mentioned on the video:
xclk_freq_hz is the frequency of the clock signal of the camera, not the crystal frequency, like mentioned. The value of 20000000 Hz is one of the possible values that should be used for the OV2640 (note here: https://github.com/espressif/esp32-ca...)
fb_count is the number of frame buffers to be allocated (not the number of frames, like mentioned).

You can find more information about the camera driver here: https://github.com/espressif/esp32-ca...
