PICBASIC PLUS Compiler5.43. OUTPUTSyntax :Overview :Operators :OUTPUT Port . PinMakes the specified Pin an output.Port.Pin must be a Port.Pin constant declaration.Example : OUTPUT PortA.0 ‘ Make bit-0 of PortA an outputNotes :An Alternative method for making a particular pin an output is by directlymodifying the TRIS: -TRISB.0 = 0‘ Set PORTB, bit-0 to an outputThe above method is quicker, and produces less code than the OUT-PUT command.All of the pins on a port may be set to output by setting the wholeTRIS register at once: -TRISB = %00000000‘ Set all of PORTB to outputsIn the above examples, setting a TRIS bit to 0 makes the pin an output,and conversely, setting the bit to 1 makes the pin an input.85Copyright Crownhill 2001
