Newbie help. RGB Led on a PIC10F202

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.

[cncmachineguy]

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.

[cncmachineguy]

Well thats just wierd that it skips blue always. but the the whole circuit turning off makes perfect sense. If you look at the gp3 pin, it is input only because it is shared with MCLR. that is the external reset pin. Since you have no configs listed, I assume you are using the defaults. I went and looked at 10f202.inc in the PBP folder and the default config has MCLR_ON. this means GP3 is set to be the reset when low. so I am sure you are reseting the chip, or at least not looking at it as an input.

2 choices here: Assuming you are NOT using PBP3, you can change the .inc file to MCLR_OFF and leave it as that, or you can comment the configs all together and put them in your code;

If you are using PBP3, you can use the brand new #config block format and set your configs in your code

BTW, I am going to assume the blue not working may have something to do with the MCLR issue for now. Also I guess you are right about the TRIS, but I would get in the habit of just ALWAYS setting it. Life will be easier later for you that way.

Last edit: Please post your current code now so we know where you are.
