Hey all, I was trying to load the module for the MPL115A2 bari pressure sensor, to no avail. I keep getting an error saying:

Uncaught Error: Field or method "getData" does not already exist, and can't create it on undefined

I also have the model MPL3115A2, the more accurate version (I am building a digital weather station) so I was wondering if the module needed tweaking?

I tried replacing all the modules instances of 'MPL115A2' with 'MPL3115A2', but this .getData error is in the way of knowing whether she'll work.

Thanks for the help!

What's your code look like?

I don't see how you can end up with that error if connect() doesn't give an error (if connect() errors, it won't correctly create an MPL115A2 object - and in that case those errors are the ones that matter)

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
