LCD 2x16 alphanumeric display

[trancient]

is it true that LCD alphanumeric can act as capacitor also?

I'm pretty sure, no.

Not unless you use it to seperate some plates for a really big capacitor.

 

[tresca]

technically...in all fairness...you can unsolder a capacitor FROM the character display..and use that

True, expensive, but true

thanks

thanks a lot. i want to test an alphanumeric 16x2 LCD. does anyone knows how to test if it is functional or not? i have tried connecting pin 1 to ground,pin 2 and 3 to 5 volts. i leave pin 15 and pin 16 unconnected. I have an LCD with 16 pin and i want to know if it is damage or not.

The LCD controller needs to be intialised, either by using an MCU or the parallel port of a PC.

Look on the web for PC port to LCD connections.

what about PIC16f84A with 18 pins to LCD 16x2 alphanumeric interfacing? i have only PIC16f84A. maybe i should try from the basic.

i haVE A PROBLEM TOO>> is anyone done in interfacing LCD display JM1602M and KS0066U as IC driver
