+Acceleration/deceleration can be simulated with the locomotive interface parameter __**[[:loc-int-en#mass|Mass]]**__. (10ms resolution.)\\
+A mass value of 5 will increase/decrease the PWM 1 step at every 5*10ms.\\
+Vstart and Vhigh, CV2/CV5, can be simulated with the __**[[:loc-int-en#step_range|Step range]]**__\\
+===Electronic Speed Controller===
+An **E**lectronic **S**peed **C**ontroller, ESC, on pin D5 can also be used for motor control if this option is set.\\
+Note: __**Only connect ground and PWM in case the ESC supports BEC.**__\\
+ \\
+====ID-12LA====
+{{ :arduino:rfid-card-antenna.jpg?200}}{{ http://id-innovations.com/httpdocs/assets/immage/id12new.jpg}}
+Optional a RFID reader from type [[http://id-innovations.com|ID-12LA]] can be connected to the RX pin for detecting tags which will be reported to Rocrail.\\
+The tag is used as **[[:sensor-gen-en#id|Sensor ID]]** or **[[:sensor-int-en#uid-name|UID-Name]]**, **[[:can-gc4-en#rfid_notation|decimal dot formatted]]**.\\
+The **[[:gca_rfid-en|GCA RFID]]** board can be used to mount and connect the ID-12LA.\\
+__The serial monitor will be set to 9600bps.__\\
+**Note:** This is to scan tags between the rails to let Rocrail know where the running vehicle is.\\
+ \\
+====RailCom====
+{{ :arduino:railcom_cutout.jpg?400}}
+The serial connector on the WIO PCB can be used to connect it to an amplifier for reading RailCom data.\\
+The GCA214 can be used as amplifier.\\
+The following RailCom IDs are supported:
+^ ID ^ Channel ^ Description ^
+|  0  |  2  | POM read |
+|  1  |  1  | Low decoder address |
+|  2  |  1  | High decoder address |
+The only way to activate RailCom reading in WIO is to set this option in the WIO Dialog. (WIO 0.105, Rocrail 2.1.212)\\
+The serial bps will switch to 250000, and the monitor will be read only. __So with this option active its not possible to setup the WIO by monitor commands.__\\

+====Sensors====
+{{ :arduino:bmp280.jpg?140}}{{ :arduino:tsl2591.jpg?140}}
+One BME280/BMP280 sensor, connected to I2C, is supported for temperature, pressure and humidity.\\
+The USER_ALTITUDE in the USERCNF.h must be adjusted to meet the local altitude for correct pressure values.\\
+One TSL2591 'Light-to-Digital Converter' sensor, connected to I2C, is supported for calculating brightness.\\
+===Dynamic Text===
+Temperature, pressure and humidity can be used as text and XMLScript variables.\\
+See: __**[[:text-gen-en#dynamic_text|Dynamic Text]]**__ \\
+ \\
+====Sound====
+Sound can be played on ESP32 boards using one of the DAC pins. (GPIO25 or GPIO26)\\
+Supported [[ https://de.wikipedia.org/wiki/RIFF_WAVE|RIFF Wave]] format:
+  * PCM type
+  * Sample rate 11.025 Hz
+  * 16 sample bits
+  * One channel (Mono)
+===Action===
+  * Type: Sound
+  * Command: Play
+  * Parameter: Sound file incl. path like: "/F9.wav"
+  * Interface Bus: WIO ID
+Example:
+<code xml>
+<ac id="F9" cmd="play" param="/F9.wav" type="sound" iid="WIO" bus="38" addr="0" port="0"/>
+</code>
+===Recommendations===
+The DAC is only capable to use 8 bits. The 16 bit data must be interpreted, which is not possible without data loss.\\
+To get the best result:
+  * Normalise the sounds files so the data uses the full 16 bit.
+ \\
+====StepMotor====
+The WIO-02 supports two types of step motors: 4-wire and 3-wire step driver.\\

+The WIO CAN type can be used as CAN-WiFi bridge for

+  * RCAN, type TCP+binary on port 5550

+The Lolin D1 must be connected to 5V USB without power supply from the CAN bus.\\
+A WIO-CAN kit will become available.\\
+ \\
+====ESP32====
+The current WIO firmware, 1.94, does use the internal CAN controller, and uses therefor only the MCP2551/2561. (SPI CAN is no longer supported for the MCP2515)\\
+In case of ESP32 the CAN communication is always activated, independent of wich WIO type is selected.\\

+=====Mobile RFID reader=====
 The WIO can also be used as mobile RFID reader and I/O.\\
 The WIO ID must be set in the loco **[[:loc-int-en#secondary_address|Secondary Address]]** field.\\

+====Very slow====
+If an I2C module, like the Pi02 or Pi03, is connected to the I2C bus of the WIO, and has no power, it will slowdown the processing and no other I2C devices are detected. (Multiple seconds between the loop calls.)\\
+The P82B715 I2C-bus extender seems to drain the I2C clock and data lines, which will confuse the ISR in the Wire library.\\
+The Pi08, with the PCA9622 chip, does not suffer this problem with its internal I2C-bus extender.\\
+===Solution===
+Make sure all conneted I2C modules are powered up at the same time as the WIO.\\
