PORTC.4 and C.5 not responding to inputs.

As usual, 18F2550. I am trying to use these ports as inputs. According to the datasheet, making UCON.3 = 0 turns off the USB and allows the pins to be used as inputs.

I have a switch on each of these pins that goes high when pressed. Nothing happens within the program whenb pressed. What should I check for next?

Code:

Define OSC 8
OSCCON=110000
DEFINE ADC_BITS 10
DEFINE ADC_CLOCK 3
DEFINE ADC_SAMPLEUS 50


DEFINE CCP1_REG PORTC 'Hpwm 1 pin port
DEFINE CCP1_BIT 2    'Hpwm 1 pin bit


ADCON1 = 001011
ADCON2 = 001010


TRISA = 111111
TRISB = 000000
TRISC = 110001

CMCON = 7
UCON.3 = 0

portc.1 = 0

alpha var byte
PCBTEMP var word
CURRENT var word
LEDS var byte
alpha = 0
LEDS = 0
pcbtemp = 0

;--- The Main Loop ---------------------------------------------------------

alpha = alpha + 10

pause 200
IF portc.4 = 1 and LEDS <5 then 'portc.4 = number of LED's lit goes up (0-5LED'S)
pause 100
LEDS = LEDS + 1
pause 100
endif




IF portc.5 = 1 and LEDS >0 then  'portc.5 = number of LED's lit goes down (5-0LED'S)
pause 100
LEDS = LEDS - 1
'IF LEDS = 0 then
'LEDS = 0

endif


IF LEDs = 0 then

endif

Ok, I hate it when this happens because you look like such a fool!

UCFG.3 = 1 (this turns off the USB Transceiver which you also have to do to enable RC4 and RC5 as inputs.)

:uncomfortableness:

I can delete the thread for you if it makes you happy. :D

I'm kidding, this could help someone else. Configs can be such a pain sometimes.

In an ideal world, PICs would know what we want even when we don't. LOL

Only if you start an identical thread tomorrow!
