PIC16F88 senior design

[skimask]

DEFINE OSC 8
TRISA.1 = 1
TRISA.2 = 0
LOOP:
IF PORTA.1 = 1 THEN HIGH PORTA.2
GOTO LOOP

END

Also if the PIC is outputing a high and I remove the high input I would expect the output to drop as well, but it doesn't. Do I need to include a second IF, THEN statement to achieve this result?

If you read the code inside your 'LOOP', there's nothing there to tell the pin to go low if the input goes low...therefore...

DEFINE OSC 8
TRISA.1 = 1
TRISA.2 = 0
LOOP:
PORTA.2 = PORTA.1
GOTO LOOP

Also, check your datasheet regarding PortA and analog settings, section 12.0 of the PIC16F88 datasheet. You might see something there that might throw a wrench into your master plan!
