Topic: expected '}' at end of input - WITS END! (Read 167 times) previous topic - next topic

Hossifer

Please, please, please, for the love of GOD, help me figure this out...

I have successfully used this code numerous times, now two IDEs on two computers refuse to compile it successfully.  Could someone please try it with their own?  I either get the "expected '}' at end of input" or a long list of errors relating to the libraries that I mostly don't understand.

Thank you, in advance, so much, for your help.

-Sincerely,

Bill Hawes.

Please do this:
  • When you encounter an error, you'll see a button on the right side of the orange bar "Copy error messages" in the Arduino IDE (or the icon that looks like two pieces of paper at the top right corner of the black console window in the Arduino Web Editor). Click that button..
  • In a forum reply here, click on the reply field.
  • Click the </> button on the forum toolbar. This will add the forum's code tags markup to your reply.
  • Press "Ctrl + V". This will paste the error between the code tags.
  • Move the cursor outside of the code tags before you add any additional text to your reply.


If the text exceeds the forum's 9000 character limit, save it to a .txt file and post it as an attachment. If you click the "Reply" button here, you will see an "Attachments and other settings" link.

Serial.print(F("DMP Initialization failed (code "));


It's got some crazy String happening. Check your quotes.
Throw a little karma my way. What goes around comes around.

Curious why you have semicolons placed thusly:

Code: [Select]


void setup(); {...

void dmpDataReady(); {...

void loop(); {...

That's tricky. My mistake.

Here I am talking about strings meanwhile, I'm counting parens.
