 		 #37864 - RE: Voltage Difference Between Grounds
Responding to: ???'s previous message
The problem is that there is a voltage difference between the grounds of circuit and PC. Sometimes when the circuit is connected to the PC, MCU is freezing
My guess is that you are discharging some (stray) capacitance. Does it EVER fail if you connect to the PC BEFORE applying power?
