hi guys,I'm learning ee. I mistaken by connect HD44780's Gound pin to 5V power and the Chip heat up greately, Would that destroy it? Since from the beginning I never make it show any char at all that I don't know whether it is ruined or not?
I'm using LCD module on breakboard and 5V power from USB charger. I'm just trying to make it show any char by connecting LCD pins to 5V or Gnd. pin 1 to G,pin2 to 5V, pin 4 float, pin 5 to Gnd, pin 6 to 5V....would that work?

I think you destroyed the IC by connecting its power supply backwards.
