Error While Uploading to Arduino Uno

Projects Programming

While attempting to save and upload to Arduinio Uno, I receive the following error:

typeError: Cannot read property 'length' of undefined

This error appears in a red band above the compiler output, as apposed to an error message within that output.

If I just click the Verify check mark button, it verifies without error. The error is only receive when I go to upload.

Thanks,

You think it might help if we can look at your sketch?

I tried to upload it using the local IDE, and I think i see the problem now - the sketch is too big:

Global variables use 2002 bytes (97%) of dynamic memory, leaving 46 bytes for local variables. Maximum is 2048 bytes.
Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
Error compiling for board Arduino Uno.

So I guess I either need to trim it down or upgrade to a Due?

Have you put F(“”) round all your strings to keep them in flash?
