This one?
That's an AVR register, isn't it?

In future, just post the error message too.

Didn't the compiler also complain about the FastLED references?

achavez2021 · June 3, 2021, 7:23pm

I do not know what an AVR register is as this is one of my first times using Arduino.
My bad I will add it

anon73444976 · June 3, 2021, 7:25pm

So what do you think an "OCR0B" is?

It must mean something or you wouldn't have arrays of them

achavez2021 · June 3, 2021, 7:36pm

Alright well for full context this isn't my project. It is my friends and I'm helping him right now, but I have never used this code before. It is like trying to read German. So yeah I don't know what an AVR is or what it's for.

achavez2021 · June 3, 2021, 7:37pm

Looking at his code now I see that he has something called LEDarray that isnt defined. Think that could be the cause of the problem?

anon73444976 · June 3, 2021, 7:39pm

So can we get your friend to tell I what s/he thinks an array of registers is supposed to do?

(I've often wondered if German COBOL puts the verb at the end of the statement)

achavez2021 · June 3, 2021, 7:46pm

He does not know either

anon73444976 · June 3, 2021, 7:47pm

There's at least one missing "#include" at the top of the sketch, but the missing array is the least of your worries.

achavez2021 · June 3, 2021, 7:49pm

Ok just added the "#include" and its looking for a file. What file does it need?

anon73444976 · June 3, 2021, 7:50pm

Have you tried some of the FastLED library examples?

When is our assignment due to be handed in?

achavez2021 · June 3, 2021, 7:51pm

No we havent, I will take a look.

Due next week, June 10th

anon73444976 · June 3, 2021, 7:55pm

The original code looks like it may have had some anti-plagiarism traps edited-in.

Still, you've got plenty of time to work on it

Good luck.
