Thermometer: Measure temperature with LM35 and show on LCD

Since we learned ADC example, now we can make a digital thermometer. LM35 gives voltage output linearly calibrated to voltage, such as 

temperature=volt/100

So, everything is the same as in ADC example with a few changes

Proteus: instead of POT resistor we put LM35 and connected to RA0

XC8:
code is as below. to calculate volt I multiplied with 500 (temperature conversion coefficient is 100). I added celcius char 223 to the screen before C. That's all.
don't forget to copy myxlcd.h, myxlcd.c and delays.h to local project directory.



#include "mcc_generated_files/mcc.h"
#include "myxlcd.h"
#include "delays.h"
#include <stdio.h>

void main(void)
{
    // Initialize the device
    SYSTEM_Initialize();

   unsigned char v[12];
    uint16_t cV = 0;
    float  volt;
 
    while (1)
    {
        ADC_StartConversion(channel_AN0);
        while(!ADC_IsConversionDone());
        cV = ADC_GetConversionResult();
        volt=cV*500.0/65536;
        sprintf(v, "%.1f", volt);

        OpenXLCD(FOUR_BIT & LINES_5X7);
        WriteCmdXLCD(DON&CURSOR_OFF&BLINK_OFF);
        while(BusyXLCD());
        putrsXLCD("Thermometer");
        SetDDRamAddr(0x40); // goto second line
        while(BusyXLCD());
        putrsXLCD("Temp=");putrsXLCD(v);putcXLCD(223);putrsXLCD("C");
        __delay_ms(500);
    }
