and when i connect the VCC of the LCD to the power supply, the power(from VCC) falls to 2 volts from the actual 5V which i am giving....i dont know why??
two possibilities: 1) your power supply (7905 or whatever) goes in current or thermal limit, check datasheets. 2) you are connecting it wrong (e.g. is it LED backlight where YOU are supposed to provide a series resistor). Erik |
