16 Pins LCD In Proteus

[shan_ahmed]

Hello everyone, i want a 16 pins lcd in proteus, where to slect it? model nmbr?? Please

I want 16x2 LCD having 16 pins, LM016L has 14 pins

I've got this circuit and i want to run it on proteus, Image below

[shan_ahmed]

I've uploaded the circuit wich i want to stimulate on proteus..
In the circuit there is a LCD having 16 pins, but LM016L has 14 pins, please help..
How can i design this circuit on proteus??

That circuit wouldn't work in real life (at least not reliably). I doubt anyone ever implemented it for real.
It is missing capacitors on the oscillator pins so the microcontroller probably never executed a single instruction.
It's also missing any decoupling. Also, the supply rail looks like it
doesn't connect to the transistor collector points (badly drawn circuit). Reset circuit components are sized
inappropriately (no reason to use an expensive 10uF 63V capacitor).
Conclusion: just because it's on the internet doesn't mean it's a good circuit to copy.

 

[shan_ahmed]

It says its a 16x2 LCD, LCD-016m002B, i've also attached it's data sheet..

I've got its code to0o..
May b e it helps. code...

...and what a surprise, the code is as bad as the circuit.
It constantly loops the LCD initialize routine and repeatedly prints the same text.

Use a 14 pin lcd instead.

 

[shan_ahmed]

Use a 14 pin lcd instead.

How to do that?? wot to do with remaining 2 pins??

 

[bigdogguru]

How to do that?? wot to do with remaining 2 pins??

If the LCD is HD44780 compatible the remaining two pins are for a backlight, pins 15 and 16 in the schematic you'll uploaded, which are certainly not a requirement for a successful simulation.

Simply leave them disconnected.

Sorry bro im a beginner, how to know if it is HD44780 compatible??? ::sad:
And which pins should remain disconnected?? i've uploaded the cicuit-diagram to0o, can u give it a look and tell me??
And data sheet of LCD is also uploaded..

 

[bigdogguru]

As I've indicated in my previous post, pins 15 and 16 of the LCD in the schematic you've posted in reply #3 are for a backlight which are not necessary.

Therefore a 14-pin LCD model which uses an HD44780 compatible controller should work fine for your simulation.

The LCD you've selected utilizes a KS0066 controller which I believe is compatible with the HD44780 controller.

You need to study the datasheet of the LCD to ensure the proper pinout as they vary from one vendor to another.

Don't assume they are in the same order as the schematic you've posted.

If your LCD uses KS0066 as the datasheet you have uploaded in post #7 then it is HD44780 compatible.

Thankeuuuuuuuuuu Jestin...It really helped me
I've another problem with microcontroller 89c51, it has no 20th and 40th pin in proteus.. w0t shud i do0 now..??

Hey i cant connect wires with this LCD :-( Just now i tried, it is of no use, :-(

 

[hemnath]

As 20th and 40th pin are Gnd and Vcc. It is internally connected in proteus.
