What's withrottle?

This is truncated JMRI WiThrottle server implementation for DCC++ command station based on ESPDuino (ESP-13) shield

Adding support of ESP8266 board to Arduino IDE

• Start Arduino and open Preferences window.
• Enter http://arduino.esp8266.com/stable/package_esp8266com_index.json in to Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
• Open Boards Manager from Tools > Board menu and find esp8266 platform.
• Select the version you need from a drop-down box.
• Click install button.

Sketch uploading

• Connect USB to UART converter to ESP13 UART connector.
• Don't forget swith it to 3.3 voltage level
• Connect pin D0 of ESP13 side connector to Ground.
• Connect USB to UART converter to PC.
• Select ESPDuino (ESP-13 Module) form Tools > Board menu.
• Select USB port from Tools > Port menu.
• Click upload button or select Upload from Sketch menu.

Board installation

• Disconnect USB to UART converter from ESP board.
• Remove jumper wire between D0 and Ground pins.
• Switch SW1 to ON.
• Remove jumper wires from Motor Shield board.
• Install ESP board atop of Motor Shield board.
• Connect jumper wires to Arduino side connector between D5 and D13 pins, and between D10 and D12 pins if you use Arduino UNO DCC++, or between D2 and D13 pins for Arduino MEGA DCC++.

How to use

• Turn power ON on DCC++.
• Open WiFi settings on mobile device.
• Find and connect to «withrottle» network.
• Start Engine Driver or WiThrottle app on mobile device
• On Engine Driver select ESPWTServer on Discovered Servers
• On WiThrottle app go to Settings page, select «Server Configuration», and turn on «Use automatic network configuration». Restart WiThrottle app.
