wat help to display on Lcd using microc

[nicko-391]

how does value(integer) stored in variable directly display on LCD display? is there any command to do that?

Try reading through the board, there are lots of threads/replies on the subject of displaying contents on LCD, read the datasheet of LCD, normally its HD44780.
Keep the sample code and datasheet side by side and you will understand the command structure.
If you are using C for programming both Hitech and CCS have sample code in their directories.

Hi nicko-391,

LCD can only display it's character-code. It has been tabulated in LCD datasheet (eg for HD44780 check https://www.sparkfun.com/datasheets/LCD/HD44780.pdf)

There you may see "code" for each and every character. Always you have to use this code to command LCD to display relevant character.

So, your variable-value must be equal to this code to directly write it on LCD.

Otherwise;
If you generate some number in variables (say 10,12,13...) and stored in memory-registers, you can not directly put them on LCD to write (to display digits 10,12,13...). They have to be converted to LCD code. You have to program for this convention.

You may see ASCII-value is the LCD-code for English alphabet and digits in HD44780 datasheet.

You may read some LCD sample programs as abidr suggested.

Hope this helps you,

}

Thank you dinesh,i choosed BASIC COMPILER to do this.
