Help with pedestrian crossing program in MPASM assembler

[prinsloo]

flowcode sample .fcf

Dear Members

I have written this pedestrian crossing, the one that I uploaded earlier.There is a problem when I send it to the PIC.
It does not work as it is suppose to-the simulation is a flowcode simulation and it work perfectly.

Included is the fcf file,hex, .asm, lst file.

I had to change:
_option_register to opt (see example)


pclath equ 0x0a ;1
intcon equ 0x0b ;1
opt equ 0x81 ;1
trisa equ 0x85 ;1
trisb equ 0x86

movlw D'192'
bsf STATUS, RP0
movwf OPT
label_0006
bsf STATUS, RP0

AND FCV_KEY equ 0x12 ;1
WAS _FCV_KEY equ 0x12 ;1


FCV_COUNT2 equ 0x10 ;1
FCV_WAIT equ 0x11 ;1
FCV_KEY equ 0x12 ;1
FCV_POLL equ 0x13 ;1

clrw
movwf FCV_KEY
movf FCV_KEY, W
btfsc STATUS, Z

Now the lights change without the button.

I use a MPASM assembler / programmer.I want to program a PIC16F84A.

The person that helps me will be thanked properly.
Thanks in advance.

Johan

Re: Help with MPASM pls

Check whether your configuration bits are correct or not

Help with MPASM pls

Dear Members

I figered out what the problem is but I dont know how to change it. The flowcode program program the switch as
'ReadState (WhichSwitch)
This macro reads the state of a single switch, specified by the WhichSwitch parameter. The macro returns 0 if the switch is open or 1 if the switch is closed.'

The proto board I have returns 1 if the switch is open or 0 if the switch is closed.

How do I fix it? Can anybody please asist me? I don't know how to change the .asm file (download the RAR file).

Regards
Johan
