I had burn several LPC1114 in the circuit below.After I use it for hours, the PWM signal produce by LPC1114 became square wave limited between 3.3V and 2.5V. Is it possible that the LPC1114 is too unstable.Or the value of the resistor is not proper,or the may be sth. wrong with other parts of my circuit?
