  2. what do you mean sir by 11,32 VDD I have used this PIC 16F877A was advice VDD 5 Volts max and pin 1 for reset used 10 K resistor in this calculation I never got the display working I am going to try your way of 5 volt with 4k7 resistor and see what happens , if you mean the VDD should be 11,32 vots we must have a current limitation to what ?
