Simple TTL input pin coding.

This should make it work

TRISA.5 = 1 'make porta.5 input

ANSELA.5 = 0' make porta.5 digital

LED VAR LATC.3 ' Use lat for output and port for input

It's really important to search and study the datasheet for answers. Read the datasheet starting at page 178 "Analog Control"

pescador, "ANSELA = PORTA.5" != "TRISA.5 = 1 'make porta.5 input". You are setting your ANSELA SFR to either %00000000 or %00000001, depending on the state of PORTA.5. Neither will do what you want.

Read the data sheet - love that answer.. First of all I wouldn't even think to look at the analog portion of the documentation since I'm not using analog inputs. The fact is the pins are defined as analog by default would have been good to know obviously. In any case - I got it to work using your code. Thank-you.
