i got this error;

***Error24"C:\program Files(x86)\PICC\devices\16F877.h" Line2(9,17): Unknown device type "16F877.H"

whatz the way out?...i also have observed that this error comes up after every compilation.


Regards

Hi bioda, why are you placing this file: C:\Users\xyz1\Desktop\xyz_new\lab tutorial.h in the header of your program? As I told you before, I would like to see their content.

Greetings!

Hi bioda, why are you placing this file: C:\Users\xyz1\Desktop\xyz_new\lab tutorial.h in the header of your program? As I told you before, I would like to see their content.

Greetings!

 

[bmb_10]

Ok, why are you using it? Delete that line and recompile. In that file is declared almost the same that is in 16F877.h, and you can't declare two or more times many of these things. Remember that the header order is always as follows (also change this):

#include<16F877.h>
                            
#fuses HS,NOWDT
#use delay(clock = 10000000)
#use rs232(baud=9600,parity=N,xMIT=pin_C6,rcv=PIN_C7,stream=RS232,bits=8)

Greetings!

 

[bioda]

hi bmb_10,

thanks for your response and time.

am afraid i still av same error, even after making the changes you outlined.

regards

Hi bioda, I have reviewed your program and there were still some things that were not in the order that requires the CCS compiler (remember studying well the book). Here is the fixed code. Instuctions that is commented out you don't need it by now:

#include<16F877.h>
#fuses HS,NOWDT
#use delay(clock = 10000000)
#use rs232(baud=9600,parity=N,xMIT=pin_C6,rcv=PIN_C7,stream=RS232,bits=8)
// the RS-232 port is set up. this line is given for future references.
// it can be deleted from the code. the intention is to write the 
// number on the PC screen via RS-232 using hyperterminal application
 
// #include<stdio.h> //header file for PIC16F877 is loaded

void main(void)
{
   unsigned int z;
   setup_adc_ports(NO_ANALOGS);
   setup_adc(ADC_OFF);
   setup_psp(PSP_DISABLED);
   setup_spi(SPI_SS_DISABLED);
   setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
   setup_timer_1(T1_DISABLED);
   setup_timer_2(T2_DISABLED,0,1);
   port_b_pullups(TRUE);//sets the port B input pullups
 
   // set_tris_d( 0x00);//all bits of port d is set for output
   // set_tris_b( 0xFF);//all bits of port b is set for input
 
   while(true) // since 1 is always TRUE this loop will go on forever
   {
      z=input_b(); // take the input from portB
 
      output_d(z); //output the same number to portD
      printf("\n\r %c",z); // prints the xter to the RS-232 hyperterminal screen
                     // assingn this line as a commment for now since the RS-232
                     // communications isnt covered
       
   } // end of while loop
} // end of main loop

Remember that this program will display its output by RS232 and you need the proper circuit to connect to the PC. In the book you can see how to do it.

Greetings!
