Newbie help. RGB Led on a PIC10F202

[brianmorris]

Steve, wonderful examples, I think th OP may have a few questions for you, especially in the last with port indexing. But why doesn't his work after he moved the IF into the switchloop section? BTW, he will still have problems with button press being 1 for a zillion loop iterations, don't ya think?

@Brian, if you press the switch repeatedly, will that make the other LED's light? If so, does it seem to be random as to which will light?

Many thanks Steve for those examples. I tried both of your last ones just above this post and neither seem to be working. It does not light upon circuit power nor if i press the button to cycle through the other colors.

Ok, new test for you to try. First make sure all three PWM's are working.Let you main call them 1 at a time like this:

main:
gosub red
gosub blue
gosub green
goto main

I know you said in your first post that all three worked, lets just be sure, then we can build on that .

Works perfectly. Didnt work at first, but then i forgot the OPTION_REG.5 = 0 had to be put into the code for GPIO.2 to work.

Does the whole thing work, button and everything?

[brianmorris]

No just the code that you asked me to try.

Now let's make sure that button is working. Modify the main to be this:

main:
Gosub red
If button =1 then goto skipgreen
Gosub green
Skipgreen:
Gosub blue
Goto main

That should have all three lit as before unless you press the button, then it should skip the green gosub. Btw, is the tris for the button set to input? Also I am a lazy typer, so I assume you will make the names be what they need to be like button shoud really be switchpin (i think)

[brianmorris]

Im not sure how to set tris on GPIO.3 I assumed because the datasheet says its an input only pin, i didnt have to futz with it. When i run your code above, i get Red, Green, Back to Red. If i tap the switch, the whole circuit turns off and stays off while i hold it. I never see blue.
