Scrolling text 2x16 LCD PIC16F887

[gabriemrc89]

hy i want to scroll some text on my lcd 2x16.
on first line i want my name end on the second line some data collect from senzors( collecting data from senzos is done).
i just need some code lines to scroll that information whit diferent speeds on the two lines if can help me please tell me

i want the 1st line scroll like second line but diferent speed

What development software are you using? MPLAB, MPASM, Hi-Tech C, CCS, MikoC, etc?

i use mikroC.

Here's a PIC project using MikroC which scrolls text across LCD remotely controlled via serial port to PC:

A PIC Serial LCD project

You should be able to download the project code and use it as a template for your program.

i start to read now i hope this information resolve my problem. i don't need to use comunication whit pc

If you have a similar PIC as was used in the project, make any modifications you need and run it to see the features.

Running the program as a demo with give you some incite into the code routines you are interested in.

I would also check the MikroC libraries, I thought I saw scrolling text routines last time I looked.

I own MikroC Pro, but rarely use it. I prefer other compilers.

i can't download anything

Well that disappointing.

The good news is I checked MikroC's libraries and they support scrolling text:

char i;                              // Loop variable

void Move_Delay() {                  // Function used for text moving
  Delay_ms(500);                     // You can change the moving speed here
}

void main(){

  ANSELH = 0;
  C1ON_bit = 0;                      // Disable comparators
  C2ON_bit = 0;

  Lcd_Init();                        // Initialize LCD

  Lcd_Cmd(_LCD_CLEAR);               // Clear display
  Lcd_Cmd(_LCD_CURSOR_OFF);          // Cursor off
  Lcd_Out(1,6,txt3);                 // Write text in first row

  Lcd_Out(2,6,txt4);                 // Write text in second row
  Delay_ms(2000);
  Lcd_Cmd(_LCD_CLEAR);               // Clear display

  Lcd_Out(1,1,txt1);                 // Write text in first row
  Lcd_Out(2,5,txt2);                 // Write text in second row

  Delay_ms(2000);

  // Moving text
  for(i=0; i<4; i++) {               // Move text to the right 4 times
    Lcd_Cmd(_LCD_SHIFT_RIGHT);
    Move_Delay();
  }

  while(1) {                         // Endless loop
    for(i=0; i<8; i++) {             // Move text to the left 7 times
      Lcd_Cmd(_LCD_SHIFT_LEFT);
      Move_Delay();
    }

    for(i=0; i<8; i++) {             // Move text to the right 7 times
      Lcd_Cmd(_LCD_SHIFT_RIGHT);
      Move_Delay();
    }
  }
}

The code above is an example of move text left and right. Checkout their LCD library documentation in the IDE.

Let me know if you have any more problems implementing your project.

the code work very fine i use that for start i can't figure out how to scroll the bought lines in the same time but with diferent speeds

I'm a beginner. Can anyone provide a CCS C Compiler code for the same function???:-|

you want just to scroll text on a single line??

hi, can is use this code?? i use mickro c
Lcd_Custom_Config(&PORTB,0,1,2,3, &PORTC,4,5,6);
LCD_Custom_Cmd(LCD_CURSOR_off);// Turn cursor off
LCD_Custom_Cmd(LCD_CLEAR);
can i use 2 diferent ports(B for data and C for lcd command)???
is much simple to proiect the hardware. i did some tests but the answear "controller received data whilst busy"
