To work around this send the byte to set the motor speed and direction in a periodic and repeating manner. This means that if a byte is sent and not recived this is no indication that anything has gone wrong. When sending command bytes to the RoboClaw from a microcontroller there is no error checking or acknowledgement that a byte has been received.

The RoboClaw maps the byte value to speed and direction as shown in the table below.Ĭommunication Issues in Standard Serial Mode The “write” function of the serial object does just this given a valid value between 0 and 255. In standard serial mode the RoboClaw accepts single bytes to control both motor channels.

In the sketch only one function is called when communicating with the RoboClaw: Step seven explains how the sketch should run the motors. If you run into a problem check that there is a ground connection between the RoboClaw and Arduino and that there is a solid connection between pin 11 of the Arduino and the S1 header signal pin. Once the sketch starts running motor 1 should run in the fowards direction, pause and then run in the backwards direction.

Download the sketch for this App Note from here. Finally disconnect the RoboClaw in Motion Studio.įigure 2: Configuring standard serial mode in Motion Studio.Ħ. Save the setting to the board by selecting “Device” from the menu and selecting “Write Settings”. Now move down to the pane labeled “Serial” and set the baudrate to “38400”. In the pane labeled “Setup” set the control mode to “Simple Serial”. On the left-hand side of the application click on “General Settings”. Open BasicMicro Motion Studio and connect your RoboClaw as done in the tutorial linked in to step 1. Ground pin on S1 header (pin closest to inside of board)įigure 1: Image of the Arduino and RoboClaw wired together.ĥ. S1 singal pin (pin closest to edge of board) Wire the Arduino and RoboClaw together with jumper wires using the table below as a reference.

Disconnect power from your RoboClaw if you haven’t already done so.ģ. (1) computer with BasicMicro Motion Studio installed Let’s get startedĢ. This App Note will cover the wiring, configuration and a test sketch for the Arduino. The Arduino is a quick and easy way to test this functionality out or for final use in a robotics project. In standard serial mode the RoboClaw accepts byte commands from any microcontroller that can send them over a serial connection.
