Hi I'm using the pc Case USB LCD Project for a digital termometer with the LM35 sensor this is the code for read temp

unsigned char readTemperature(void)
{
unsigned char temperature;
int result;
float temp;


// Perform ADC on RA0 to read the LM35 voltage output
GODONE = 1; // Start the ADC conversion
while(GODONE); // Wait for the ADC conversion to complete

// Get the ADC result (1023 = +5v (5000 milliVolts)
result = ADRESL;
result += (ADRESH << 8);


// Calculate the current temperature
temp = round( result * 0.488 )+2;


// Return the temperature to the nearest degree C
temperature = (unsigned char)temp;

return (unsigned char)temperature;
}

when i try to display at the lcd using
lcdGoto(0,1);
lcdPuts(readTemperature);
i get this Warning 141.20 illegal conversion of integer to pointer
and the display showme some wrom caracters

could you helpme with this convertion ?

You have to convert the integer to a string in order to display it.

Include the string functions ( #include <stdio.h> ) and then use something like:

char myString[4];
sprintf(myString, "%d", myInteger);

then print the contents of 'myString' to the LCD. You could even use:

sprintf(myString, "Temp = %d", myInteger);

if you want some extra text (make sure the myString array is long enough though).

Thanks to you as always it worked just fine

Hi do you have any code to interface the dallas DS1820 I@C termometer chip with Hi-Tech C ?

I haven't used that chip personally; usually I2C is quite simple though, just find an I2C example for the PIC and alter it according to the data-sheet for the device.
