Synopsis

This is the layout template for emsa and emsb mini project. Each group can post a blog based on this template. This project is to use LCD using PIC16F877A. Using 16×2 Character LCD is a very basic LCD module which is commonly used in electronics projects and products. It contains 2 rows that can display 16 characters. Each character is displayed using 5×8 or 5×10 dot matrix. It can be easily interfaced with a microcontroller.

  TRISB = 0x00;
  TRISC = 0x00;
  Lcd8_Init();
  while(1)
  {
    Lcd8_Set_Cursor(1,1);
    Lcd8_Write_String("electroSome LCD Hello World");
    for(i=0;i<15;i++)
    {
      __delay_ms(1000);
      Lcd8_Shift_Left();
    }
    for(i=0;i<15;i++)
    {
      __delay_ms(1000);
      Lcd8_Shift_Right();
    }
    Lcd8_Clear();
    Lcd8_Set_Cursor(2,1);
    Lcd8_Write_Char('e');
    Lcd8_Write_Char('S');
    __delay_ms(2000);
  }
}

We need to add header file lcd.h



The code for lcd.h is shown below,
