Ok, I was working on my new program, made a few changes in MPIDE, and then hit the download button. I get the Uploading to I/O Board, my application resets and runs, and the progress bar halts at around 12%. I have a bunch of messages in the status box like:
at java.util.regex.Pattern$Loop.match(Pattern.java:4295) at java.util.regex.Pattern$GroupTail.match(Pattern.java:4227) at java.util.regex.Pattern$BranchConn.match(Pattern.java:4078) at java.util.regex.Pattern$CharProperty.match(Pattern.java:3345) at java.util.regex.Pattern$Branch.match(Pattern.java:4114) at java.util.regex.Pattern$GroupHead.match(Pattern.java:4168) at java.util.regex.Pattern$Loop.match(Pattern.java:4295) at java.util.regex.Pattern$GroupTail.match(Pattern.java:4227) at java.util.regex.Pattern$BranchConn.match(Pattern.java:4078) at java.util.regex.Pattern$CharProperty.match(Pattern.java:3345) at java.util.regex.Pattern$Branch.match(Pattern.java:4114) at java.util.regex.Pattern$GroupHead.match(Pattern.java:4168) at java.util.regex.Pattern$Loop.match(Pattern.java:4295) at java.util.regex.Pattern$GroupTail.match(Pattern.java:4227) at java.util.regex.Pattern$BranchConn.match(Pattern.java:4078) at java.util.regex.Pattern$CharProperty.match(Pattern.java:3345)

Anyone seen this before, and have any ideas how to solve it? I need to get on with my troubleshooting!

Hi,

Which chipkit board are you using and what version of MPIDE are you using? Try compiling and loading an example sketch such as the blinkyLed and see if you get the same error. Make sure the right serial com port is selected and the board too.

That looks like the preprocessor failing to parse your sketch. Check your comments, they are the most common cause of the parser failing - especially an unterminated multi-line comment.

Sorry, didn't get a chance to re-post yesterday.

Finally found the problem. It was a syntax error in the middle of things that drove the pre-processor nutso. It happened when I went to reload my software after a couple of minor changes onto the Max32, so I thought it was something entirely different.

Fun part was that the error was no where near where I was making changes, so I have no idea why they happened!

Just for grins and giggles, I ran into this problem again today! What caused it? I had a line: Serial.print("Serial Number: );

Note that there is no ending " before the closing parenthesis! No error, it just sent the pre-processor into a tizzy!

Is there somewhere you can file bug reports for MPIDE?

Post them on Github:

Or just use UECIDE as I completely re-wrote the preprocessor from scratch and it's perfectly happy with missing quotes:
