modbus in 16f887 "modbus_phy_layer_rtu.c " this sa
PostPosted: Mon Apr 15, 2013 3:15 pm     Reply with quote
I am trying to implement modbus protocol in a pic16f887. I have the version 4.140 compiler. I use the project wizard option and when I wish to compile the program, it shows a error in the line "#USE TIMER(TIMER=1,TICK=.1ms,BITS=16, ISR)" of "modbus_phy_layer_rtu.c ". This say "line 25(9,47):internal error - contact ccs ppuse"


Code:
#include <v2.h>


#define MODBUS_BUS SERIAL
#define MODBUS_TYPE MODBUS_TYPE_SLAVE
#define MODBUS_SERIAL_TYPE MODBUS_RTU
#define MODBUS_SERIAL_RX_BUFFER_SIZE 64
#define MODBUS_SERIAL_RX_PIN PIN_C7
#define MODBUS_SERIAL_TX_PIN PIN_C6
//#define MODBUS_SERIAL_ENABLE_PIN PIN_
//#define MODBUS_SERIAL_RX_ENABLE PIN_
#define MODBUS_SERIAL_BAUD 9600
#define MODBUS_OUR_ADDRESS 230
#include "modbus.c"
void main()
{   boolean respond = false;
   modbus_init();
   fprintf(SLAVE_PC, "\n\rReady...");

   while(TRUE)
   {
      while(!modbus_kbhit());
      fprintf(SLAVE_PC, "\n\rBus Active");

      if((respond = (modbus_rx.address == MODBUS_OUR_ADDRESS)) || modbus_rx.address == 0)
      {
         fprintf(SLAVE_PC, "\n\rRequest for us");
         fprintf(SLAVE_PC, "\n\rFunction: %X", modbus_rx.func);
         switch(modbus_rx.func)
         {
            case 0x01:
               if(respond)
               {
                  //read the coils
               }
               break;
            case 0x02:
               if(respond)
               {
                  //read discrete inputs
               }
               break;
            case 0x03:
               if(respond)
               {
                  //read holding registers
               }
               break;
            case 0x04:
               if(respond)
               {
                  //read input registers
               }
               break;
            case 0x05:
               break;
            case 0x06:
               break;
            case 0x07:
               break;
            case 0x08:
               if(respond) {modbus_diagnostics_rsp(MODBUS_OUR_ADDRESS,
                              make16(modbus_rx.data[0],modbus_rx.data[1]),
                              make16(modbus_rx.data[2], modbus_rx.data[3]));}
               fprintf(SLAVE_PC, "\n\rResetting...");
               reset_cpu();
               break;
         }
      }
   }

   setup_comparator(NC_NC_NC_NC);// This device COMP currently not supported by the PICWizard

}


Code:
#include <16F887.h>
#device adc=16

#FUSES NOWDT                    //No Watch Dog Timer
#FUSES HS                       //High speed Osc (> 4mhz for PCM/PCH) (>10mhz for PCD)
#FUSES PUT                      //Power Up Timer
#FUSES NOBROWNOUT               //No brownout reset
#FUSES NOLVP                    //No low voltage prgming, B3(PIC16) or B5(PIC18) used for I/O

#use delay(clock=20000000)

#use FIXED_IO( A_outputs=PIN_A7,PIN_A6,PIN_A5,PIN_A4,PIN_A3,PIN_A2,PIN_A1,PIN_A0 )
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8,stream=SLAVE_PC)


can any help me to resolve this problem?

It compiles with no errors for me. I made it all be one file.
I didn't include the bottom code as v2.h, I just put it at the top of
the main code. I used compiler vs. 4.140.

From the .LST file:
