I am using MPLAB XC8 LCD Library.

  1. By converting floating point value to string and display that sting using Lcd_Write_String()
  2. By separating each digits and display that digit using Lcd_Write_Char() after converting it to character

The second method is the best method but it will vary depending upon the length of values that to be displayed.

........
#include<stdio.h> 
......
...
...
void main()
{
  char s[16];
  float f;
  ........
  ....
  while(1)
  {
    ....
    ...
    ...
    sprintf(s, "Float = %f", f);
    Lcd_Set_Cursor(1, 1);
    Lcd_Write_String(s);
    ...........
    .....
  }
}

a = ADC_Read(0);
involts =a*5000/255;
delayMs(10);
{
  Lcd_Clear();
  Lcd_Set_Cursor(1,1);
  Lcd_Write_String("Mains");
  /*
    Lcd_Set_Cursor(1,10);
    Lcd_Write_Char(involts%10 + 48);
    involts = involts/10;
    Lcd_Set_Cursor(1,9);
    Lcd_Write_Char(involts%10 + 48);
    involts = involts/10;
    Lcd_Set_Cursor(1,8);
    Lcd_Write_Char(involts%10 + 48);
  */
  sprintf(s, "Float = %f", involts);
  Lcd_Set_Cursor(1, 10);
  Lcd_Write_String(s);
  Lcd_Set_Cursor(1,13);
  Lcd_Write_String("VOLT");


found error as

lib\doprnt.c; 837. bad call to typeSub()

  • Try using the latest compiler
  • Make sure that you properly set the pic type in configuration
  • Try recreating the project after deleting all files
