Programa nao compila no Mikro C

Leandro Rebello · 3 de junho de 2017

Pessoal, me ajudem por favor a entender o que realmente acontece com o codigo abaixo que nao complina no MIKRO C PRO 5.61.

Estou usando um PIC18F452. Quando removo a linha 62 " Xa = counter1 * enc_const * 1000 ; ", o programa compila, mas foge da ideia de variar o valor de Xa en funcao do valor de Counter. A funcao criada e apenas para exibir numeros com decimais no LCD, sem uso de Float.

Obs: Estou usando um LCD I2C, abaixo do codigo vou colar a biblioteca do I2C LCD.

Peco ajuda de vocês.

Segue codigo:

#include "Lcd_I2C_PCF8574A_Lib.h"

//=============================================================================
// --- Protótipo das Funções ---
void display_dec(long decimal);
//=============================================================================
// --- Variáveis Globais ---

char Lcd_I2C_address ;

const float enc_const = 0.002778;

long counter1, Xa, Xp, decimal;

// --- Função Principal ---
void main()
{

ADCON1 = 0x0F; //Apenas entradas digitais
TRISB = 0xFF; //RB0 e RB1 como entrada
TRISC = 0xF8; //RC2,RC4 E RC5 como saida
TRISD = 0xFC; //Todos como entrada

counter1 = 10;

LATC2_bit = 0x00; // en_pwm
LATD0_bit = 0x00; //LATC0_bit do motor 1
LATD1_bit = 0x00; //LATC1_bit do motor 1

LATC0_bit = 0x00;
LATC1_bit = 0x00;

Lcd_I2C_address = 0x7E;

Xp = 288.520 * 1000; // posicao programada em milimetros sem virgula 9,000 mm
//Xa = 135.389 * 1000;

I2C1_Init(100000); //Inicializa protocolo I2

Lcd_I2C_Init();

Lcd_I2C_Out(1,1,"XP:");

display_dec(Xp);

while(1)
{
Lcd_I2C_Out (3,1,"Xa:");
Xa = counter1 * enc_const * 1000 ;
display_dec(Xa);

counter1--;

delay_ms(200);

}//End while

} // end main

//=============================================================================

//=============================================================================

void display_dec(long decimal)
{
unsigned int cen, dez, uni, dec1, dec2, dec3;
long x1, x2;

x1 = labs(decimal);
x2 = 1000;

cen = (x1 / x2)/100;
dez = ((x1 / x2)%100)/10;
uni = (x1 / x2)%10;

dec1 = ((x1 % x2)*10)/ x2;
dec2 =((((x1%x2)*10)%x2)*10)/ x2;
dec3 =((((((x1%x2)*10)%x2)*10)%x2)*10)/ x2;

if (decimal > 0 ) Lcd_I2C_Chr_Cp ('+');
else Lcd_I2C_Chr_Cp ('-');

Lcd_I2C_Chr_Cp (cen+48);
Lcd_I2C_Chr_Cp (dez+48);
Lcd_I2C_Chr_Cp (uni+48);
Lcd_I2C_Chr_Cp ('.');
Lcd_I2C_Chr_Cp (dec1+48);
Lcd_I2C_Chr_Cp (dec2+48);
Lcd_I2C_Chr_Cp (dec3+48);

}//End display_dec
