Part Number: MSP432P401R
Hello,
I'm currently using the MSP432 Launchpad to control a small mobile robot. The robot will not be attached to a computer via USB while it is running.
I have tried attaching 3.3V from my external voltage regulator to the microcontroller by attaching the voltage and ground from the external regulator to 3.3V and ground on J16. I have also removed the 3.3V jumper on J11. The microcontroller does not turn on unless I have the microcontroller connected to my computer via USB. If I disconnect from the computer, though, the microcontroller still runs, implying to me that the microcontroller is getting power from the external 3.3V, just not at the beginning?
I have also tried the same result, but removed the 5V jumper on J11 and got the same result.
How am I supposed to power the microcontroller externally, without using the USB?
Thanks,
James
