Can you post the link for Violet LCD model of Proteus you are using?

Sorry my friend moments when I use Proteus are very rare, I use real parts to save time.


Its LCD Screenshot Generator, you can download it from here:

Re: Help me to control the push button ...

I forget to tell you, this code uses 155 bytes of RAM and requires 1736 bytes of ROM, what fit in your PIC16F877A which have 368 bytes of RAM and 14KB of ROM.

Look to use some newer uC with more resources and higher capabilities such as PIC18F46K22, of course for less money.

Today all day I was in a crowd, I've entered the home before 30 min. :|

See this example:

RC0 - change selection
RC1 - choose selected option
RC2 - back to main menu

Note: RC0,RC1,RC2 should be in pull-down.

LCD Screenshots :

When you power device LCD show main menu :

When you press RC0 selection mark is showen '>' :

After proper selection we call selection with RC1 and second menu opens :

Again we use RC0 for selecting options :

No prob my friend,

If you have lots of screens this can be cheap solution, but for advanced look and projects consider GLCD 128x64 with touch screen, there is more space for datas and options. Also there is Touch LCD 2x16.
