Hello, new here so please be easy on me. I have a robo claw 2x60 motor controller. I am trying to control it via serial connection on pins S1. I am using a microcontroller called EZB 4. I have set the robo claw to mode 5, and baud rate to 38,400. When I send a command the motors start and run in opposite directions and never stop. My code was very simple.

SendSerial(D0,38400,255)
SendSerial(D0,38,400,127)
Sleep(3000)
SendSerial(D0,38400,0)

Code should start motors, run and then stop. The motors continue to run and will not stop until I physically remove the battery. I have confirmed serial Mode 5 by the 5 flashes in menu#1 and comm speed 38,400 by 4 flashes in the menu#3. Can anyone help? I have posted at the microcontroller site to no avail. Thanks Chris

Do you have a Roboclaw or a Sabertooth. Sabertooth(by Dimension Eng)? If looks like you are trying to send a baudrate detection byte(255) which we don't support. Our simple serial mode requires you have the baudrate already set correctly. So you should be able to remove the 255 command. ALso you must set the board to simple serial mode. By default the boards are set to either USB mode or Packet Serial mode.
