DRV2605LEVM-MD: User switch

Part Number: DRV2605LEVM-MD

Hello, in the manual it is said at 3.3 User Switch : 

" At board startup, the capacitive touch buttons are automatically enabled and USB communication is disabled even though USB communication was initialized. To enter USB communication for use with the multi-driver graphical user interface (GUI), the user switch must be pressed. LED1 turns to indicate that the firmware is active for USB transactions. When the user switch is pressed and the board is in USB communication mode, the capacitive touch buttons are disabled. A power cycle or software reset is required to go back to capacitive-touch mode. "

Does it mean there's no way to fix the board on USB communication mode and get it by default each time power is recovered ?

My goal is to use the board  in a system running daily, in which a computer control the motors via USB.



  • Hi FD, 

    this would require changes to the MSP430 firmware on the EVM. Since this isn't available you could consider powering the MSP and DRV devices externally and leave them powered at all times, and then use USB for only control from the PC.
