Tool/software: Code Composer Studio
The following phenomenon has appeared in use:
After the system is turned on, the light source is not lit (the light source needs the MSP430 to send the I2C command to light), the MSP430 hangs up and the program runs away.
In actual test, the MSP430's power supply is 3.32V. When it is turned up to 3.54V, sometimes the light source can be lit, and then the MSP430 will soon hang up.
The MSP430 chip was taken down and re-welded, and the phenomenon did not change.
What are the possible reasons that led to this phenomenon?
