How to set a pin high an keep it there?

[ShortBus]

Utter newbie here... I have three different LEDs on a PIC16F688. Here is my code:

symbol  GREEN = PORTA.1
symbol  ORANGE = PORTA.0
symbol  BLUE = PORTA.2

porta = %00000000
trisa = %00000000

main:
high orange
pause 1000
high green
pause 1000
high blue
pause 1000

end

This code obviously lights the LEDs in sequence. However each LED turns off before the next one is set high. How do light one, then two, and then all three? Thanks!

Try this:

main:

PORTA = %00000001
pause 1000
PORTA = %00000011
pause 1000
PORTA = %00000111
PAUSE 1000

end

It looks like you are experiencing a read-modify-write problem. You can search for more info on this forum.

INCLUDE "AllDigital.pbp"

symbol  GREEN = PORTA.1
symbol  ORANGE = PORTA.0
symbol  BLUE = PORTA.2

porta = %00000000
trisa = %00000000

main:
high orange
pause 1000
high green
pause 1000
high blue
pause 1000

end

Will do the same as Darrel's suggestion and this

plus the data sheet will actually help you learn why.

Sure,
But if you run ALLDIGITAL first, then you know where to look in the datasheets, because it's already told you what settings you need to use.
If you want to learn, look them up.

People never find the analog registers they need to set by looking in the datasheet first.

If you keep going with all of your add ons (includes) you will have any PIC as easy as a STAMP.

What is the maximum amount of includes you have used in a program?

[Darrel Taylor]

I hope not ... Stamp's don't bring back any memories of "Easy" for me.

What is the maximum amount of includes you have used in a program?

Probably 12-15, but I've never really counted.

90% of my programs only have 2 includes.
care to guess which ones?
