To begin with, have you added the 16F877a .INC file at assembly time?

Like at the start. While making asm file . Yes i did. The code looks perfectly fine to me but i don't know why isn't it running

All those errors (and maybe warnings) are for you to correct or adjust something.

The soon you start, the better.

Hey are coming since I've started writing include. Wish you could've helped more

##### Active Member
Each error message contains a line number.

First error is at line 4
The error message is misleading, but examine line 4 and you should spot a glaring error.

fix line 4 and every similar line

Second error should then become the first error in the list
Second error is at line 12. The error message is this time clear and accurate. You have already defined PORTA in your include file. Delete line 12, you do not need it.

Always look at the first error in the list - or maybe first few errors. fixing one early error might also fix many later errors

Can you please tell what exactly is the error. Is it indentation or spelling. I'm sorry but I'm totally new to the synatx

Please can you tell what symbol is missing in line 4. Sorry to bother but its completely new to me

##### Active Member
no symbol is missing

Do not take error messages too seriously. Some times the message is helpful, sometimes not
The assembler simply cannot make any sense of ------ and has to make a guess at what you intended to do.
The assembler has no understanding of what you intended to do, so often it guesses completely wrong, as in this case

If you INCLUDE the the .inc file as Max suggests in post #2 you don't need to define the the addresses of registers as this is what the .inc file does.
This is the line I used in a program using a PIC16F677A
#include <p16f877A.inc>

Your subroutines for bank selection will not work as they do not end with a RETURN instruction.
There are other ways to do this.
You could write a macro to do it.
Here is an example of the macro. This code includes the macro up to the first time the macro is used.

Code:

If you do a search for "macro" (Without the inverted commas.) you will see where it is defined and used.

Yet another way is to use the banksel directive

[code}
banksel OSCCON

MOVLW B'11101010' ;Value for 4 Mhz
MOVWF OSCCON
[/code]

You just follow the banksel directive with the name of the register you are about to use. You don't need to look up which bank the register is in.
EDIT. I have just noticed that the example macro is for a PIC with a bank select register.
You will have to put the bit set and bit clear for the status register in your macro.
You will have to have a different macro for each bank as you can't pass the bank number as a parameter as it can't
just be loaded into the status register in the same way as it can to the BSR.

Thankyou so much for your reply. If i write return ti the subroutines would it be of help. And if i only use banksel irrespective of using subroutines for bank switching. Would it be good enough. As i Don't know what micro is Don't know how it works like

If you download the Micro Chip User guide for the Assembler ( DS33014H).
You can look up the Error number flagged and see the description.
Section: Errors, Warnings, Messages and Limitations.

You will find details of using macroes and the banksel directive in the documentation that Max has pointed out in post #14.
Your "Duplicate label ("PORTA" or redefining symbol that cannot be redefined)" error id because PORTA has already been defined in the .inc file.

You have many lines consisting of --------------. This isn't valid, remove them all. Your subroutines should always end with return and never goto.

So should i remove only porta or even statuses and other tris

Remove them all, as they are already in the include file.

Remove them all, as they are already in the include file.
So how will it distinguish between differen statuses. They all have tge same name. Or is it when i use banksel, it will call the respective bank?
