thank you for you help!!

This is not very clear, however it seems that you are using 2 drives here ( C:\ & D:\ ) and you have not specified the paths correctly, in other words half the data is on drive c: and the other half on drive d: and with the path not specified it cannot execute.Try moving the data on drive d: to your c: drive, or specify the path in your autoexec.bat.

Hope this helps.

thank you ,

today i have seen the datasheet of the 16f877 .it says function shouldn't exceed 2k. so it doesn't like 8051 .is realy? how could i avoid that?

thank you for you help!

The 16 series (and others) uses banked codesegment if a function needs more than 2K you must split it into at least 2 smaller functions because it is not possible to generate more than 2K continuos code.

But you must take care that the stack size is limited to 8 on the PIC 16F877 (and others).

how to scan a variable in picc

Hello Kerden,
I'm not an expert.

But seems like you need to post some code. May someone could spot it for you.

 

[kerden]

picc nop

think you for all help!

i don't understand how to stick the code on it .

it seems not allow me to stick such large code in the forum,and who can tell

me how to stick.

i am very sorry.i come from china and know little english.so i can't faultlessly

express my meaning.but i hope i can get help from you .

thank you !

You can either post a few lines only your error is indicated at line 51 of main.c so you could post lets say lines 45 to 60 or you can make a zip or rar archieve of your sourcecode and add it as an attachment.

hope this helps and best regards

fixup overflow in expression mplab

thank you !

originally i want to make the project into RAR or ZIP.

but now i could stick them into three part.

there are three file about C 1:my_eeprom.c 2:my_i2c.c 3:main.c

include two file about define 1:my_eeprom.h 2:my_i2c.h

beacause i finish them just now ,there isn't any explaintion for sentence.

Hi

I made a quick scan of your main.c with PCLINT here is the result:

I would start to correct these problems and then try to compile the code

there is some variable undeclare. i have modified and compiler
the result as follows:

generally speaking when your mouse double click the error and the mouse will jump to the error .but there is an error "Errow[000]" appears, this kind of solution will be invalid

I am sorry but you must post your code again (as an archieve please) as you have edited your source and the line numbers do not make sense with the version I have...

hi

i have made them into RAR,you could loaddown the project it will show what i

said.

thank you !

function not made in the presence of a prototype

i think there isn't any solecism because the error at the [000] address. so it

must be a address overflow. and i have to cut any function to prove where the

error making .as follows:

"D:\i2c eeprom\hex\my_i2c\hex\run_mode.obj" -M"3.map" -O"3.cof" -O"3.hex" -Q -MPLAB -16F877A
Error[000] run_mode.rlf 60 : Fixup overflow in expression (loc 0x71 (0x71+0), size 1, value 0x101)
Error[000] run_mode.rlf 80 : Fixup overflow in expression (loc 0x71 (0x71+0), size 1, value 0x100)
BUILD FAILED: Sat Jan 15 00:52:58 2005

so i have to cut down any big function "bit Auto_Run(void);bit Unauto_Run

(void);bit Hand_Mode(void);bit Wait_Time_Pass(const uchar time_temp,const

uchar water_mode_temp)".and then it could compile successful;

but when i add the function"bit Wait_Time_Pass(const uchar time_temp,const

uchar water_mode_temp)" it shows the error information liking above ;

and then i disable line "//Read_time(time_buff);" and the error still appearance

in my opinion the function"bit Wait_Time_Pass(const uchar time_temp,const

uchar water_mode_temp)" isn't any big .so it wouldn't Fixup overflow ;

but where is the error comes from?

mplab error undeclared identifier

Hi kerden,

I took a closer look at your code and have edited it so it compiles successfully with PICC 7.87 PL2 that I am using.

Your main problem was that you are missing Unauto_Mode I have put in a dummy function.

Also check the calls to Wait_Time_Pass where I had to change the first argument.

I also had to rename my_eeprom.c and my_eeprom.h to myeep.c and my_eep.h because of the dos filesystem that my compiler is using

best regards

fixup overflow picc

hi,i am kerden.

thank you for answered my question.
i could share the Internet until the day before yesterday.
so i haven't seen you reply about my quesetion.i am so sorry for that.
today i have ckecked in you project.and still have a question:
when i include the "run_mode.h" in the main project.the compiled show many error
but when i copy the code to the main project and compile pass?
why?

thank you !
