    2. Example Code for Arduino-Analog Mode Control

    It is the easiest way to run the motor in Analog Mode. Even you haven't connect the analog signal to Veyron, the motor could run once you set the Veyron in Analog Mode, actually, it regard this situation as input votage signal as 0V.And if need to control the speed, the only step needed to do is to connect a 0-5V analog signal to S1/S2 as controlling signal, the speed is adjusted according to the absolute value of input Voltage, and it would stop if the valtage is 2.5V. If you need to set some paramenters to contorl the motor more precisely, you could do as follow.
    3. Example Code for Arduino-PPM Mode Control

    In this example, the PPM signal is created by a program, you could copy that from this passage below into Arduino IDE.
    4. Example Code for Arduino-UART Mode Control

    Here, in UART mode. There are two things you can do. First one is very useful: to set some parameters and read what’s inside of Veyron. Second, you could control the motor by a program in the interface. Ready? So, let’s get start.

    FAQ

    • Comman wiring mistakes might cause unexpected problem, like: The motor is not response to the command or signal, or the motor can not rotate continuously. You can check if you made some mistake in the list below.
      Please check:Bad/ loose connection. That is some bad wire or wrong connection. One possible wrong connection is happened on the connecter, showing as the picture at right.Tx and Rx connected wrong. Generally, the connection should be Tx-Rx, Rx-Tx (Device A - Device B), but some product is designed for special purpose that the lable Tx on PCB is Rx actually, if so, you would better check its schematic to see if it's ture and exchange the Tx, Rx connection.If you connect the wires + and - of power supply in reverse way.
