Compiler Errors

I do not know what the problem is but i can't get rid of these compiler errors, would anyone have any idea? I am a beginner with programming PIC's. The errors are listed below following the code that the compiler does not like. Any help here would be greatly appreciated. I am using a PIC16F628

Message[302] C:\KEYPAD.ASM 36 : Register in operand not in bank 0. Ensure that bank bits are correct.
Message[302] C:\KEYPAD.ASM 38 : Register in operand not in bank 0. Ensure that bank bits are correct.

BSF STATUS,5
MOVLW b'11111000'
MOVWF TRISA
MOVLW b'11100000'
MOVWF TRISB

Warning[205] C:\KEYPAD.ASM 290 : Found directive in column 1. (end)

Error[173] C:\KEYPAD.ASM 291 : source file path exceeds 62 characters (C:\KEYPAD.ASM)

Error[173] C:\KEYPAD.ASM 291 : source file path exceeds 62 characters (C:\P16F628A.INC)

just a simple question here. wich software do you use to compile assembler ? MPLAB?

In case you use PicBasic your assembly language lines will not work insead you do not declare these lines as assembly section.

ASM
bsf PORTA.0
....
ENDASM

Hi Conspiracy Bro,
On the"message 302"s - I think that's because TRISA and TRISB are both in memory bank 1.

The ASM command sets the bank to zero, so you'll have to set the bank back to 1 in your ASM section before modifying the TRIS registers.

Make sure to re-set the bank as needed before leaving the ASM section.


<<<EDIT>>>> Duhh - I now see you did that already...

After a few try, i appear that you'll always get error when dressing to TRIS. there's another method and it will gives you also an error message

like this:
MOVLW b'11111000'
TRIS PORTA
MOVLW b'11100000'
TRIS PORTB


They will say that is not recomended...bla bla...

In your case

Code:

---

list p=16f628
include "p16f628.inc"
org 000H
goto start

ORG 005H

start CLRF PORTB
      CLRF PORTA
      BSF STATUS,RP0 ;SWITCH TO BANK1
      MOVLW b'11111000'
      MOVWF TRISA
      MOVLW b'11100000'
      MOVWF TRISB
      BCF STATUS,RP0 ;RETURN TO BANK0

      ;place you code there
      ;

END

---

this is working but with error message bullsh... on BANK0 that we set correctly... as i expect.
