Hi,
I have some simple problem. I am using Stellaris eval board in my application, where i use external power supply. On Stellaris board i put +5 V from 7805.
My question: if I put USB for debugging purpose, and turn on external power supply, the system will work correctly, and i will be able to program/debugg?
Or is it not possible, because USB voltage may be lower than 5 V, and then external power source will try to beat USB voltage, and current will run trough my PC?
Best regards,
Marcin Lis
