-=====WIO=====
-//WIO Version 1.14+//\\
-Le fonctionnement du CAM dans le contexte WIO réduit le nombre d'image par seconde à 10 à la résolution QVGA. (Des taux plus élevés sont possibles)\\
-====Configuration====
-^ Réglage ^ Valeur ^
-| type WIO | CAM |
-| Type de carte | ESP32-CAM |
-====URL====
-===WEB Browser===
-<code>
-http://<WIO IP>:8081/stream
-</code>
-===Text===
-<code>
-mjpg:<WIO IP>:8081:tcp:stream:<rotate90>
-</code>
-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:\\
-{{:arduino:camera-long-connection.jpg?200}}
-===Locomotive===
-{{:arduino:wiocam-loco-int-en.png}}\\
-====I/O====
-Some ports can be controlled with an output:
-  * Bus = WIO ID
-All other settings are default.\\
-^ GPIO ^ Usage ^ Output ^ Type ^
-|  4  | Flash LED |  1  | Accessory |
-|  -  | Snapshot |  2  | Accessory |
-|  -  | Snapshot + Flash |  3  | Accessory |
-|  12  | H position servo |  1  | Servo |
-|  13  | V position servo |  2  | Servo |
-|  2,14,15  | Output |  4,5,6  | Accessory |
-File names used for snapshots on SPIFFS are generated:
-<code>
-/<00000000>.jpg
-</code>
-The zeros represent the lower 32 bit part of the millisecond counter.\\
-Existing files will be overwritten.\\
-====Arduino IDE====
-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:\\
-{{:arduino:esp32-s-cam-wrover.png?400}}\\
-The mounted camera must be selected in ''CAM.h''.\\
-For this test board select:
-<code c>
-#define CAMERA_MODEL_AI_THINKER
-</code>
-:!: 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.\\
- \\
-=====Power Supply=====
-After the sketch have been uploaded, the ESP32-CAM needs a solid 5V power supply to be able to startup WiFi.\\
-The USB FTDI232 board cannot provide the needed current, so the voltage will drop, and the ESP32-CAM will generate a Brownout exception.\\
- \\
-=====Pinout=====
-{{:arduino:esp32-cam-pinout-1.png}}\\
-  * GPIO04 = Flash LED
-  * GPIO33 = on board LED
-  * GPIO16 = Seems to be used by the camera. (I2S)
- \\
-=====Control=====
-{{ :arduino:esp32cam-control.png?300}}
-  * {{:arduino:cam.xml.zip}}
-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 move |  1  | Servo |  0...180  |  255  |  0...9  | |
-| 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 move |  2  | Servo |  0...180  |  255  |  0...9  | |
-| 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.\\
- \\
-=====Rotate 180°=====
-Set in the USRCNF.h the CAM_ROTATE180 to true:
-<code>
-// CAM
-#define CAM_ROTATE180 true
-</code>
- \\
