| 100 errors problem !! |

Hello,
After building my project, the code gave me 100 errors all the same and i don't know how to fix it.
The errors are:
Expecting a declaration
Expecting a (
Expecting an identifier
Thanks.
This is my code:
| Code: |
#include "demo.c"
#FUSES NOWDT //No Watch Dog Timer
#FUSES WDT128 //Watch Dog Timer uses 1:128 Postscale
#FUSES XT //Crystal osc <= 4mhz for PCM/PCH , 3mhz to 10 mhz for PCD
#FUSES PUT //Power Up Timer
#FUSES NOBROWNOUT //No brownout reset
#FUSES NOPBADEN //PORTB pins are configured as digital I/O on RESET
#FUSES NOLVP //No low voltage prgming, B3(PIC16) or B5(PIC18) used for I/O
#FUSES NOXINST //Extended set extension and Indexed Addressing mode disabled (Legacy mode)
#use delay(clock=4000000)
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8,stream=PORT1)

I know this gives errors in 5.019 you should include {} on the output_low as well
| Code: | if(level==0)
{ output_low(PIN_A1); }
else{
output_high(PIN_A1);
counterL=counterL-1;

What is this LCD driver ? Why are you including the init routine from
the LCD driver in your program as a separate routine ? Where's the
#include near the start of your program for this lcd driver ? It's missing.
What's in this file ? Post it. |

The first thing is demo.c.
Generally, the _only_ include that should be done before the fuses and clock, is the actual processor definition. Anything that requires serial I/O, timings etc. etc., is dependant on having the timings, RS232 etc., defined first. Since demo.c, must include an LCD function (which will use timings), this is not the way to get it working....
Then CCS has a 'traditional' problem, that certain types of error, will only get reported, when the compiler can't cope any more. When this happens you then get dozens of errors on the next few lines. This is commonly caused by something like an imbalanced bracket dozens or hundreds of lines before - I suggest in demo.c.
Move demo.c to after the fuse/clock definitions, and use the tool to match braces (or an editor with this ability of you don't have the IDE), and check that these are all balanced in demo.c.
Why waste a memory location to store 'i'?. while (TRUE) works just as well (and better since you keep assigning one to i, rather than just testing it)...
| Code: |
if(level==0)
output_low(PIN_A1);
else{
output_high(PIN_A1);
counterL=counterL-1;
}

"I know this gives errors in 5.019 you should include {} on the output_low as well".
Er. no. Not needed, and does not give errors in 5.019 (or any other CCS compiler). I'd suggest if it is giving errors for you, the instruction you are using in the single line, is not a function, but a #defined macro. This is one reason why #defines should always be in capitals. So:
| Code: |
if(level==0)
output_low(PIN_A1);
else
{
output_high(PIN_A1);
counterL=counterL-1;
}
//perfectly legal and does not give errors, but:
#define silly_thing(x) output_low(x);delay_us(1)
if(level==0)
silly_thing(PIN_A1);
else
{
output_high(PIN_A1);
counterL=counterL-1;
}
//will now give an error

 You're right. Just had a look and it is a macro |

| You have two sets of fuses, two main's etc.. Never going to work. Read the manual, look at the examples, realise that you can only have one program, and start again. |
