16F877A - problem with Port D
Hello, I am working with 16F877A which Serin some signal and put it's ports high or low. I have 4 LED's on Port B (7,6,5,4) & 4 LED's on Port D(7,6,5,4).
The one on PortD are being funny. They are not responding to the inputs. Not going high or low. I am using DT_Int in the code as well. My config values are as follows:
Code:
DEFINE OSC 4
Include "modedefs.bas"
INCLUDE "DT_INTS-14.bas" ; Base Interrupt System
INCLUDE "ReEnterPBP.bas" ; Include if using PBP interrupts
@ __Config _XT_OSC & _WDT_OFF & _PWRTE_ON & _BODEN_ON & _LVP_OFF & _CP_ALL & _CPD_ON
Pause 50
wsave VAR BYTE $70 SYSTEM
'-------------------------FUSES SET----------------------------
PAUSE 50
ADCON1=7
CMCON=7
CCP1CON=0
OPTION_REG=%10000000
TRISA=0 : PORTA=0
TRISE=0 : PORTE=0
TRISB=0 : PORTB=0
TRISC=%10000000 : PORTC=0
TRISD=0 : PORTD=0
@ ERRORLEVEL -306
Is something wrong with my fuse settings, rest everything seems fine to me.
Re: 16F877A - problem with Port D
Nothing wrong or special with PORTD on this one. Config fuses seems fine. Something's wrong somewhere in your whole code.
