Camera Webserver ESP32-CAM ESP32-WROVER-B AI-THINKER Board with LED control

Also look at Version 2 here: https://github.com/xenpac/ESP32-CAM-Linux-Motion

Overview

This a stripped down version of the esp-who camera web server example at: http://github.com/espressif/esp-who
I added the control of the onboard high-power LED to be used as flash for snapshots or illumination for streaming.
It does not use a PWM, so its ON or OFF.
The changes are all in app_http.c

Hardware: ESP32-CAM AI-THINKER Board with OV2640, that nice little CAM board sold everywhere.

Removed:

• face recognition, also removed related code in source (app_httpd.c).
• set Release Version in Menuconfig for max optimize. (debug info still output on serial).

Added:

• LED control via "Facedetection" Control. (On/Off)
• Flash control for snapshot via "Face Recognition" Control. ie. both must be active, LED will turn off and only flash on snapshot.

corrected an error at line:88 in app_httpd.c, filter changes to filter->values .

Future work will be to integrate the camera as a cheap webcam to be used with linux motion.

It looks, the camera is working stable now.

The default stream-resolution can be specified in app_camera.c, line 69.

Camera Web interfaces via http:

Webpage with config settings: 192.168.1.4 (this is an example ip on the LAN)

The following 2 interfaces only work, if not enabled in the webpage at the same time. So only one instance can be running!!

• jpeg Streaming interface (resolution asto settings on Webpage) : 192.168.1.4:81/stream

• single jpeg capture image: 192.168.1.4/capture (now supports optional flash!)

Project:

It is assumed you are familiar with setting up and using the esp32 environment.

You need ESP-IDF from: https://github.com/espressif/esp-idf The crosscompiler from: https://dl.espressif.com/dl/xtensa-esp32-elf-linux64-1.22.0-80-g6c4433a-5.2.0.tar.gz

I compiled the project using Ubuntu with crosscompiler and make.

Goto cam_server directory and edit the sdkconfig file to update your wifi AP settings.

Then type "make" to compile the project.

It also possible to use the Arduino IDE.
