new version of CCS |

dear friends
hi everybody
I use CCS PCW with the version of 3.155 recently.
When I write the line
#device PIC16F877 *=16 ADC=10 ( even at the first line of my code)
I get an following error message :
"can't change device type this far into the code".
But, when I used older versions, there were no problem with this directive.
please help me.

Show us the first part of your code |

Post the first ten lines of your code with all your <include> statements (other than comments) so we can see what you have. |

I seem to remember there was a problem about this version number, where the device with the chip type, _had_ to be seperated. There was a thread here at the time.
Personally, since you don't want two device statements with chip ID's, I'd use:
#include <16F877.h>
//This will define the device for you, and include the defintions
#device *=16 ADC=10
//This should setup the other configurations.
This way, you are setting the chip ID in one place only. If this doesn't work, I'd suspect it is just a compiler problem (it works fine on 3.156, and 3.148, which are the two versions I have 'bracketting' your version.

hi....
Here is the first lines of my code.
#include<16f877.h>
#include<stdio.h>
#include<F877.h>
#device PIC16F877 *=16 ADC=10 // I get an error here
#fuses XT,NOWDT,NOPROTECT, NOBROWNOUT, NOLVP
#use delay(clock= 4000000)
#ZERO_RAM
#priority ext, rb
#include"lcd.c"
thanks a lot for an answer

PICmicro device is defined twice |

You must omit the device declaration at
the 4th line, i.e. instead of
Code: | #device PIC16F877 *=16 ADC=10 |
it should read only
Code: | #device *=16 ADC=10 |
because the type of PIC itself is already defined
in the include file 16f877.h and it cannot
be redefined later even if you use the same device type
good luck,
