I would like to use a separate microcontroller which would be running an interactive program and sending commands using the suggested format s=1,1,1,1,1,1. However I don't plan on having the lasershark plugged into a computer. Does the lasershark have to be plugged into usb or does the firmware automatically respond to input over Uart in this format. As an alternate would the debug port be a better option to send commands to the lasershark.
