I want to use MSP430 launchpad to control a switch working between 1.65V and 2.75V. So, I wanted to force Vcc value to 2V instead of 3,3V while it is connected to my PC. I connected Vcc and GND pins to a power supply delivering 2V. But, now, I have a real problem. Even after taking off connection cables, Power led blinks and Vcc varies between 0V and 3,3V. I think that my kit doesn't work anymore. Could you tell me if it is the case.
Fortunately, I have another kit, I decided to work with it. But I don't know to force my Vcc to 2V to control my switch while the launchpad is connected to my PC.
Thank you very much ! Alice
