How to declare an array char type in a function
PostPosted: Wed Jul 12, 2017 6:14 pm     Reply with quote
Hi, I am trying unsuccessfully to declare an array char type in a function, can someone tell me what is my error?


Code:
#include <18F4520.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP,NOBROWNOUT,NOSTVREN
#use delay(clock=20MHz)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)// RS232 Estándar

#include <stdlib.h>

#define LED             PIN_D0

#define ON                 output_high
#define OFF                output_low

int const maxLongBuffRX=42;       

char bufferRX[maxLongBuffRX];       
int indBufferRX=0x00;          
char XCommand[maxLongBuffRX];    
char flag_RptaCommand;
int i;

void Add_bufferRX(char c);

#int_rda
void serial_isr() {
  if(kbhit()){
    Add_bufferRX(getc());
  }
   flag_RptaCommand = 1;
}


void Ini_buff_rec(void){

  int i;
  for(i=0;i<maxLongBuffRX;i++){
    bufferRX[i]=0x00;
  }
  indBufferRX=0x00;
}

void Add_bufferRX(char c){

  switch(c){
    case 0x0D:
      break;
    case 0x0A:
      break;
    default:
      bufferRX[indBufferRX++]=c;
  }
}

int1 SendATCommand( char CommandTX[], char RXCommand[] ){

   Ini_buff_rec();

   for (i=0; i<strlen(strlen(XCommand)); i++){
      printf ("%c",CommandTX[i]);
   }

   
   while (   flag_RptaCommand == 0);

   strcpy( XCommand,RXCommand);
   if(strncmp(bufferRX,XCommand,strlen(XCommand)))
       return(1);   
   else
       return(0);   
}

void main(){

   OFF(LED);
   if (SendATCommand("AT", "OK")){
      ON(LED);
   }

   delay_ms(200);

while (TRUE);
}

Add the line shown in bold below:
Quote:
#include <18F4520.h>
#device PASS_STRINGS=IN_RAM
#fuses HS,NOWDT,NOPROTECT,NOLVP,NOBROWNOUT,NOSTVREN
#use delay(clock=20MHz)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)// RS232 Estándar

It should now compile OK.
