Hello,
I started playing with MSP430USB launchpad a few weeks ago. After couple of rather simple exercises like LCD display and 1-wire bus which worked really nice, I decided to play with ADC12. I was surprised to see that when I was connecting +5V or +3.3V to ANALOG1 input (P6.0) my launchpad was disconnecting from my PC and LCD light was going off. The same was happening when I used other analog inputs. When I connected 4,5V battery between Analog1 and GND it was draining really huge current from the battery. Battery ran out flat after a few minutes. Even thought apparently all Aanlog inputs were on short to GND ADC12 was converting. I could see indication LED going off/on when I was connecting/disconnecting voltage from AnalogInput.
It looks my MSP430F5529 is damaged, or I am doing something totally wrong. I used example CCS ADC12 projects.
Has anyone experienced something similar on any other MSP430?
Thanks,
Jacek
