PLEASE HELP

[plt34]

Hi. I have bad english. But i hope i can what is my problem.

This code is working in isis simulation. But, when i complier that, it doesnt. I dont understand.

Code is:
--------------------------

// Set TEMP_RESOLUTION to the corresponding resolution of your DS18x20 sensor:
// 18S20: 9
// 18B20: 12 (default setting; can be 9,10,11,or 12)
const unsigned short TEMP_RESOLUTION = 12;

const int RES_FACTOR_1[4] = {5000, 2500, 1250, 625};
const unsigned int RES_FACTOR_2[4] = {0x0001, 0x0003, 0x0007, 0x000F};
const unsigned int RES_FACTOR_3[4] = {0x8000, 0xC000, 0xE000, 0xF000};
float alarma;
unsigned temp,temp2,new_temp;
unsigned short j, RES_SHIFT,j2;

void Display_Temperature(unsigned int temp) {
const unsigned short RES_SHIFT = TEMP_RESOLUTION - 8;
unsigned int temp_whole, temp_fraction;
unsigned short i;
char text[8];

// Isolate the fraction and make it a 4-digit decimal integer (for display)
temp_fraction = temp & RES_FACTOR_2[RES_SHIFT - 1];
temp_fraction = temp_fraction * RES_FACTOR_1[RES_SHIFT - 1];
//portc = temp_fraction;
// Handle the whole part of temperature value
temp_whole = temp;

// Is temperature negative?
if ((temp_whole & 0x8000) != 0u) i = 1; // Yes, i = 1
else i = 0; // No, i = 0
// PORTC = i;
// Remove the fractional part
temp_whole >>= RES_SHIFT;

// Correct the sign if necessary
if (i) temp_whole |= RES_FACTOR_3[RES_SHIFT - 1];

//portd = temp_whole;
IntToStr(temp_whole, text); // Convert whole part to string
Lcd_Out(2, 6, text); // Print whole part on LCD
Lcd_Chr_Cp('.'); // Print dot to separate fractional part


IntToStr(temp_fraction, text); // Convert fractional part to string

// Add leading zeroes (we display 4 digits fractional part)
if (temp_fraction < 1000u) Lcd_Chr_Cp('0');
if (temp_fraction < 100u) Lcd_Chr_Cp('0');
if (temp_fraction < 10u) Lcd_Chr_Cp('0');

Lcd_Out_Cp(text); // Print fractional part on LCD

Lcd_Chr_Cp(223); // Print degree character
Lcd_Chr_Cp('C'); // Print 'C' for Centigrades
}//~

void main() {
ADCON1 = 0xFF; // Configure RA5 pin as digital I/O
PORTE = 0xFF;
TRISE = 0x0F; // PORTE is input
PORTB = 0;
TRISB = 0; // PORTB is output
TRISD=0;
PORTD=0;
TRISC=0;
PORTC=0;

// Initialize LCD on PORTB and prepare for output
Lcd_Init();
Lcd_Cmd(_Lcd_CURSOR_OFF);
Lcd_Out(1, 1, "Sicaklik: ");

do { // main loop

Ow_Reset(&PORTE,2); // Onewire reset signal
Ow_Write(&PORTE,2,0xCC); // Issue command SKIP_ROM
Ow_Write(&PORTE,2,0x44); // Issue command CONVERT_T
Delay_us(120);

Ow_Reset(&PORTE,2);
Ow_Write(&PORTE,2,0xCC); // Issue command SKIP_ROM
Ow_Write(&PORTE,2,0xBE); // Issue command READ_SCRATCHPAD
Delay_ms(400);

j = Ow_Read(&PORTE,2); // Get temperature LSB
j2=j;
temp = Ow_Read(&PORTE,2); // Get temperature MSB
temp2=temp;
temp <<= 8; temp += j; // Form the result
temp2<<=5;
j2>>=3;
new_temp=temp2^j2;
portd=new_temp;
// alarma=39;
alarma=((new_temp*127.5)/255);
if(((alarma>=21.5))) { //YESİL LED AKTIF
PORTC.F0=1;
}

else {
portc.f0=0;}

Display_Temperature(temp); // Format and display result on LCD
Delay_ms(500);

} while (1);

}//~!

error is:

------------------------------

and it doesnt exist hex field.

please, please. can you send me true code? i need c code file and hex file. please.

it is my very importent homework.

Hello plt34,

Several things:

- What uC you use, also at what freq ?
- There is no LCD initialization section in your code. Also you need to include LCD and One_Wire libraries.
- I notice that you use 5.6.1 version, please update your compiler to 6.0.1 version.

LCD Library
http://www.mikroe.com/download/eng/docu ... ibrary.htm

Code: Select all

// LCD module connections
sbit LCD_RS at LATB4_bit;
sbit LCD_EN at LATB5_bit;
sbit LCD_D4 at LATB0_bit;
sbit LCD_D5 at LATB1_bit;
sbit LCD_D6 at LATB2_bit;
sbit LCD_D7 at LATB3_bit;

sbit LCD_RS_Direction at TRISB4_bit;
sbit LCD_EN_Direction at TRISB5_bit;
sbit LCD_D4_Direction at TRISB0_bit;
sbit LCD_D5_Direction at TRISB1_bit;
sbit LCD_D6_Direction at TRISB2_bit;
sbit LCD_D7_Direction at TRISB3_bit;
// End LCD module connections

Please see complete example located in compiler example folder:
C:\Program Files\Mikroelektronika\mikroC PRO for PIC\Examples\Development Systems\EASYPIC7\One Wire


Best regards,
Peter
