| Program is too large error |
 Posted: Mon Jul 23, 2012 8:30 am |

I am writing C for PIC10F200, and MPLAB is giving me the following error:
*** Error 71 "xenon.c" Line 303(0,1): Out of ROM, A segment or the program is too large MAIN
..............is this because my program is too big for the PIC10F200's ROM memory?
Here is the code...............

Yes.
The chip only allows 256 instructions _total_. By the time you have perhaps 30 or more for delays, some I/O, etc., you have 'no hope'. Try recompiling for the 202, which supports twice the ROM, and you may have a faint hope, but it is going to be very tight....

Thanks,
When i "Build All", is there any way of seeing how big the too-big program is.
so that i know how much i need to trim it back.
Also, if i call a function, can i not then call another function from within that function?
(something to do with the stack?) |

Even though your stack is tiny, a CALLABLE routine utilizing timer0, with a 16 bit argument to count a single quantity in "rollover ticks", could replace the vast amount of inline code consumption traceable to all those delay_ms/us calls.
I used that approach with an overfull 16c505 years ago, and if you really can't figure out the 'how' of it - I would post enough of what I wrote then to move you forward. |

The quick way is to do what Ttelmah suggested - temporarily change
the #include line to the 10F202.h and re-compile. The compiled code
will fit in that PIC and you can look at the top of the .LST file and see
how much ROM is used. You can also browse the .LST file and see what
code or functions are using the most ROM. |

in case it will help you :
| Code: |
// 4 mhz -> 1 mhz - div_1 , timer0 rollover = 3906 hz or 256 usec per TIX
// yielding a 16 sec total range ( bummer no OVF flag in 10f parts ;-(( )
// in main: setup_timer0 for div 1 prescalar, internal clock
// i round off to 250 usecs for simplicity
// just be sure you call with a non zero value for tix
unsigned int16 tix=1;
// set global 'tix' to the number of 250 usec increments to delay
// as this is more efficient in use of code than my original version
// as in tix=100; delay_utix256();
void delay_utix256(void){
unsigned int8 newtimer, oldtimer=0;
set_timer0(0);
do{
newtimer=get_timer0();
if (newtimer<oldtimer) --tix; // detect overflow
oldtimer=newtimer;
// also you can check an early exit condition HERE and RETURN;
}while(tix);
}

Hi Thanks,
Ive compiled with the PIC10F202.h and it says that it uses 67% ROM.
so does that mean 67% of 512 bytes = 343 bytes....meaning that i have 343-256 = 87 bytes of ROM to get rid of.
Also, how do i know how much RAM the PIC10F200 has?
I am using 25% RAM onPIC10F202.h but does that mean it'll be too much for the PIC10F200.h? |

My code is smaller now but still not small enough.
asmboy if i use your delay using the timer will that be better than using a delay_ms(10) and then calling that in a for loop for longer delays?

im just wondering if int i should be a long int in order for it to be able to count up to 210?
After all, an int is only 8 bits, and with the sign bit thats down to 7 bits which means 127 maximum? |

Data sheet is your friend.
10F200 256words of ROM, 16bytes RAM
10F202 512words of ROM, 24 bytes of RAM
So your 25% is only 6 locations, which will fit in the 200 easily.
Generally, software delays are always a little 'bulky'. The loop is tweaked in length, to give a sub time. and then called multiple times internally. I'd guess that asmboy's code will save significant amount, but not 87 words.
You can save a few more words, by switching to fast_io. You will need to add one instruction to setup TRIS then, but _every_ output and input instruction will then be one instruction smaller.
I suspect the optimiser (hopefully) will have changed:
output_bit(PIN_TRIGGER,1);
into the same code as 'output_high(PIN_TRIGGER)'. Otherwise it will be worth changing all commands where you use a 'value' like this, into the corresponding output_high/low instructions.
It really is going to be terribly tight to get this in, but I suspect with real care it might _just_ fit.

thanks,
actually ive amalgamated the functions and got it down to PIC10F200.h Size.
I am now working on disabling pullups and enabling the watchdog timer.
The compiler doesnt like me adding set_portb_pullups(FALSE).
Do you know why? |

Only one answer to this: RTFM
When working with embedded processors like the PIC you always need to have the datasheet with you. Your program is so tight connected to the hardware that you really need to know the nitty gritty details.

Good thinking, but there is also something like an 'unsigned int'. Check the CCS manual, chapter 'Data Definitions', page 43 for all the info you need.
A tip for finding the parts of code that can be optimized is to study the list file (*.lst). Here you can see the C-code and the assembly code that is generated from it.
Note: from the generated code you will see that generalizing all delays to multiples of 10ms didn't really save space. Sometimes it is, but here it is more efficient to have the compiler use one generic delay_ms call.

I checked the manual, (@ july 2003) theres nothing on page 43, page 66 lists types but theres no "Usigned int".
can you confirm that "int" can only go -127 to +127? |

No.
Signed 8 bit ints (signed int or signed int8) are from -128 to +127.
Unsigned 8 bit ints (int, int8, unsigned int or unsigned int8) are 0 to 255.
CCS C is unusual in that ints are unsigned by default: they are more commonly signed. They are also 8 bit: most C compilers int are 16 or 32 bit.

Why are you using such an old manual version?
The PIC10 series is supported by the free PCB compiler that CCS did include with MPLAB (at least they did a few years ago last time I checked). So there shouldn't be any reason to not use a recent compiler version. |
