hello
With 5V as power supply, maybe, you can destroy the LCD!
because Nominal voltage is 3,3V.
same for the control signal.
In normal runing, check if you get a voltage of 7 up to 8.6V accross the capacitor connected on pin 7 Vout.
if less than 6 V, no chance to see something on display.
some LCD 3310 have a resolution of 8 lines of 16 caracteres
other have 6 lines of 14 caracteres
.. maybe because controller are different, i was not able to check it.
I had to test many LCD to find out some working immediatly with the same program.
because , not sure of the source : coming from spare or from out of order phone Nokia.
