Want 2 Disply Multiple LCD Custom Character on the same line

[07arunsharma]

Hello!! I am using PIC16F877A micro-controller.
And i am trying to display multiple character on the same line..
But i am unable to so..
It is not displaying the characters as i want to..

it must diaplay the word Sawatam in Hindi below welcome in 2 row of LCD and then move it..
Can anyone help me..
here is my code..


// LCD module connections
sbit LCD_RS at RB2_bit;
sbit LCD_EN at RB3_bit;

~~~~~~~~~~~~~~~~

Take care of the following for your PIC

ANSEL = 0; // Configure AN pins as digital I/O
ANSELH = 0;
C1ON_bit = 0; // Disable comparators
C2ON_bit = 0;

Code: Select all

Delay_ms(200);
for(i=1;i<=16;i++)
{
Lcd_Cmd(_LCD_SHIFT_LEFT);
Delay_ms(200);

You should use "j" for this part, NOT"i"

"i" is used for the custom characters.

Check out the LCD library if you want to move the text left or right
