Topic: JSON Library? (Read 30247 times) previous topic - next topic


@PaulS - Thank you!

I spent an hour or two during over the various files without spotting that.  Amazing how much easier it is to find something when you now what you are looking for...

I've spent the last two weeks trying to collect data from a JSON parser, in a meaningful way, for several different kinds of JSON files. So, I had a fair idea about the types involved, and the inheritance, so it wasn't too difficult to find that the expected class had the expected method.
The art of getting good answers lies in asking good questions.


the arduino json library is unable to parse the following file. I have validated online that it is a valid json file...any clues as to why it might not be parsing ? it simply crashes my WEMOS MINI

here is my serial output:

waiting for parsing to occur...
