I think goto is the problem here?

is getting an error. compile it and find it. I cant seem to it.

any ideas?

help would be appreciated

Well, You could leave the GoTo out of it, and use an else statement.
Further:
Your missing like 6 (!!!) closing brackets! (})

I didn't clean your code, just removed the GoTo and added the CORRECT amount of brackets

3

woah.. all those brackets...

huh.. I thought I had tried using an else and it didn't work... oh well, msut be that alzheimers again, hitting me at 12 years old lol

4

YW

Luckily i'm not a cat because now i'm curious:
Whats your bipedal robot like? Any pictures?

5

I just put a dummy statement delay(1); after the quickstart: label, then it compiled (with the missing brackets added too!). Compiler quirk maybe.
I wouldn't recommend using goto though...

I think shortage of RAM looms large in your future.

Learn about the F() macro.

    quickstartTime + 0.01;

Adding zero to an integer and not putting the result anywhere seems entirely pointless to me.

why doesn't that work?

i'll send some pics later. it's full size 1:1 scale. for a school science fair.

yeah, heard about f() ill look into it (converts sram to flash right?)

btw AWOL it's like a counter. im still working on it

Good night from NZ. Will reply in the morning.

quickstartTime + 0.01; ???

Why does it compile?

Look at the FLASH usage, 6714 bytes with above, 7354 with quickstartTime += 0.01; and quickstartTime += 6;

Lot more going on there than meets the eye...

When you start seeing near-identical variable names differing only in their suffixes and blocks of identical code, it's time to consider arrays.
Your code will be shorter, easier to read and easier to maintain, because the bugs will have fewer dark corners to hide in.

Why shouldn't it compile?

Like I said, a lot of effort to go to for no reward (if anything, I'm a little surprised the compiler didn't optimise it out)

13

Lot of stuff I don't understand going on here but I'll resend some optimised code in the morning. Keep talking and I'll see it tomorrow. I'll also send my end goal so maybe I can rewrite the entire code with your suggestions

14

why doesn't that work?

It does, for some definitions of "work".

Simply tacking on a load of closing braces at the end wasn't the right solution.

15 
if(digitalRead(buttonPin == HIGH))

buttonPin has the value 7, HIGH has the value 1.
Because seven is almost never equal to one, reading pin zero is not what you want to do.

Tryif(digitalRead(buttonPin) == HIGH) instead.

When you do your rewrite, if your sketch is more than about 80 lines long, you've done it wrong.

I get this error when compiling in Visual Studio with the statement:

x + 1;

In CodeWarrior, I also get a Warning: expression has no side effects.

I get this error when compiling in Visual Studio with the statement:

What do you actually expect this stupid, useless, statement to do ?

Indicating that other compilers do pick up this issue?

19

it's full size 1:1 scale. for a school science fair.

I can't wait to see the size of the servos and I hope to goodness that they are not being powered directly from the Arduino.

C-F-K - thanks, you hit the nail on the head...
