|The WIO-CAM can only handle one stream client at a time.|
|Make sure the right board type is selected for ESP32-CAM.|
WIO Version 1.14+
Running the CAM in WIO context reduces the fps to 10 at QVGA resolution. (Higher rates are possible.)
The rotate90 option can be 'left' or 'right'.
This will swap from landscape to portrait, and should only be used if it is physically not possible to adjust the camera.
Alternative use a camera with a longer connection:
Some ports can be controlled with an output:
All other settings are default.

File names used for snapshots on SPIFFS are generated:
The zeros represent the lower 32 bit part of the millisecond counter.
Existing files will be overwritten.
The ESP32-CAM board does not feature an USB connector, so a separate USB programmer board is needed.
There are many clones of this ESP32-CAM board. Important is documentation on how to connect and program the board, and which camera is mounted.
This test board must be programmed in the Arduino IDE with the ESP32 Wrover Module board type:
The mounted camera must be selected in
For this test board select:
The GPIO0 must be connected to the ground pin to be able to program the ESP32-CAM.
Sometimes the reset button must be pressed too to be able to flash the WIO firmware.
Its easy to create a camera control by using Outputs as "Push buttons" in Rocview.
|Control||Address||Type||Value ON||Value OFF||Delay||Remark|
|Snapshot||2||Accessory||-||-||-||Use address 3 for activating flash light|
|Horizontal step plus||1||Servo||181…190||255||-||Step size is value ON - 180|
|Horizontal step min||1||Servo||191…200||255||-||Step size is value ON - 190|
|Vertical step plus||2||Servo||181…190||255||-||Step size is value ON - 180|
|Vertical step min||2||Servo||191…200||255||-||Step size is value ON - 190|
|Position reset||-||Servo||250||255||-||Resets both servos to 90° position.|
An OFF value of 255 prevents setting the position again at the OFF command.
