Na hora de compilar da erro na lcd_flex

[arh]

boa noite a todos, to tentando fazer um programinha aqui so pra aprender mesmo, e na hora de compilar ta dando erro na biblioteca do lcd_flex

e nao estou conseguindo resolver isto.

segue o meu codigo

 #include <16f628a.h>
#include <lcd_flex.c>
#fuses nolvp, intrc_io, nomclr, nowdt
#use delay (clock = 4000000)
/*----------------------------------------------*/
//Configurando portas

#use fast_io (a)
#use fast_io (

#bit botao_1 = 0x05.6
#bit botao_2 = 0x05.7

#priority Timer1, rtcc
/*----------------------------------------------*/
//Tratamento timer 0

#int_timer0
void trata_t0 ()
{
      static int contador = 0;
      contador++;

      if (contador ==1000)
         {  lcd_gotoxy (3,1);
            lcd_putc ("oi anderson");
            delay_ms (200);
         }
}

/*----------------------------------------------*/
//tratamento timer 1

#int_timer1
void trata_t1 ()
{
      static int contador_t1 = 0;
      contador_t1++;

      if (contador_t1 == 10)
      {  lcd_gotoxy (5,2);
         lcd_putc ("wilerson");
         delay_ms (200);
      }         
}


/*----------------------------------------------*/
//funcao principal


void main ()
{
lcd_init ();
set_tris_a (0b0000111);
set_tris_b (0xff);
setup_timer_0 (rtcc_internal | rtcc_div_16);
setup_timer_1 (t1_internal | t1_div_by_8);
enable_interrupts (global);


while (true)
{

lcd_putc ("\f");

/*----------------------------------------------*/
//botao 1 prescionado
   while (botao_1 == 1)
   { delay_us (50);
         if (botao_1 == 1)    //deboucing
         { set_timer0 (131);
           enable_interrupts (int_timer0);
         }
   }
/*----------------------------------------------*/        
//botao 2 prescionado
   while (botao_2 == 1)
   {delay_us (50);
        if (botao_2 == 1)
        { set_timer1 (15535);
          enable_interrupts (int_timer1);
        }
   }     
}
}

e segue os erros que esta aparecendo.

estranho que ta dando um erro bobo, erro no delay_us, nao to entendendo.

Ahhhh, isso é simples.

você adicionou a biblioteca:

#include <lcd_flex.c>

Mas você colocou ANTES de definir o clock do PIC.

Com isso o compilador tenta gerar os tempos da biblioteca mas nao consegue pois nao sabe a base de tempo usada.

Experimente colocar a biblioteca depois da linha:

#use delay (clock = 4000000)

Realmente é um erro bobo mas que joga no mato legal.

Falou

haha, deu certo...

deus que te abençoes mateus hehe. valeu man

agora ta compilando mas nao esta saindo do jeito que quer.

este codigo meu estaria certo? tipo, teria como ativar o timer quando apertar o botao?

a ideia desse codigo ai seria assim, se apertar e manter apertado o botao 1, ai passado o tempo do estouro do timer e tal, ele exibir uma mensagem no lcd.

obs: na hora de compilar nao ta dando erro mas ta dando aviso.
