How to display floating point values on LCD ? I am using MPLAB XC8 LCD Library.
You can display floating point values on LCD in following two methods.
- By converting floating point value to string and display that sting using Lcd_Write_String()
- 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.
Use sprintf() to convert floating point number to string :
........ #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); ........... ..... } }what wrong with me `
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 aslib\doprnt.c; 837. bad call to typeSub()
