Thank you for opening an issue on an Adafruit Arduino library repository. To
|
|
||||||
improve the speed of resolution please review the following guidelines and
|
|
||||||
common troubleshooting steps below before creating the issue:
|
|
||||||
|
|
||||||
- **Do not use GitHub issues for troubleshooting projects and issues.** Instead use
|
|
||||||
the forums at http://forums.adafruit.com to ask questions and troubleshoot why
|
|
||||||
something isn't working as expected. In many cases the problem is a common issue
|
|
||||||
that you will more quickly receive help from the forum community. GitHub issues
|
|
||||||
are meant for known defects in the code. If you don't know if there is a defect
|
|
||||||
in the code then start with troubleshooting on the forum first.
|
|
||||||
|
|
||||||
- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
|
|
||||||
check all of the steps and commands to run have been followed. Consult the
|
|
||||||
forum if you're unsure or have questions about steps in a guide/tutorial.
|
|
||||||
|
|
||||||
- **For Arduino projects check these very common issues to ensure they don't apply**:
|
|
||||||
|
|
||||||
- For uploading sketches or communicating with the board make sure you're using
|
|
||||||
a **USB data cable** and **not** a **USB charge-only cable**. It is sometimes
|
|
||||||
very hard to tell the difference between a data and charge cable! Try using the
|
|
||||||
cable with other devices or swapping to another cable to confirm it is not
|
|
||||||
the problem.
|
|
||||||
|
|
||||||
- **Be sure you are supplying adequate power to the board.** Check the specs of
|
|
||||||
your board and plug in an external power supply. In many cases just
|
|
||||||
plugging a board into your computer is not enough to power it and other
|
|
||||||
peripherals.
|
|
||||||
|
|
||||||
- **Double check all soldering joints and connections.** Flakey connections
|
|
||||||
cause many mysterious problems. See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
|
|
||||||
|
|
||||||
- **Ensure you are using an official Arduino or Adafruit board.** We can't
|
|
||||||
guarantee a clone board will have the same functionality and work as expected
|
|
||||||
with this code and don't support them.
|
|
||||||
|
|
||||||
If you're sure this issue is a defect in the code and checked the steps above
|
|
||||||
please fill in the following fields to provide enough troubleshooting information.
|
|
||||||
You may delete the guideline and text above to just leave the following details:
|
|
||||||
|
|
||||||
- Arduino board: **INSERT ARDUINO BOARD NAME/TYPE HERE**
|
|
||||||
|
|
||||||
- Arduino IDE version (found in Arduino -> About Arduino menu): **INSERT ARDUINO
|
|
||||||
VERSION HERE**
|
|
||||||
|
|
||||||
- List the steps to reproduce the problem below (if possible attach a sketch or
|
|
||||||
copy the sketch code in too): **LIST REPRO STEPS BELOW**

Thank you for creating a pull request to contribute to Adafruit's GitHub code!
|
|
||||||
Before you open the request please review the following guidelines and tips to
|
|
||||||
help it be more easily integrated:
|
|
||||||
|
|
||||||
- **Describe the scope of your change--i.e. what the change does and what parts
|
|
||||||
of the code were modified.** This will help us understand any risks of integrating
|
|
||||||
the code.
|
|
||||||
|
|
||||||
- **Describe any known limitations with your change.** For example if the change
|
|
||||||
doesn't apply to a supported platform of the library please mention it.
|
|
||||||
|
|
||||||
- **Please run any tests or examples that can exercise your modified code.** We
|
|
||||||
strive to not break users of the code and running tests/examples helps with this
|
|
||||||
process.
|
|
||||||
|
|
||||||
Thank you again for contributing! We will try to test and integrate the change
|
|
||||||
as soon as we can, but be aware we have many GitHub repositories to manage and
|
|
||||||
can't immediately respond to every request. There is no need to bump or check in
|
|
||||||
on a pull request (it will clutter the discussion of the request).
|
|
||||||
|
|
||||||
Also don't be worried if the request is closed or not integrated--sometimes the
|
|
||||||
priorities of Adafruit's GitHub code (education, ease of use) might not match the
|
|
||||||
priorities of the pull request. Don't fret, the open source community thrives on
|
|
||||||
forks and GitHub makes it easy to keep your changes in a forked repo.
|
|
||||||
|
|
||||||
After reviewing the guidelines above you can delete this text from the pull request.

Adafruit_SGP30
|
|
||||||
================
|
|
||||||
|
|
||||||
This is the Adafruit SGP30 Gas / Air Quality I2C sensor library
|
|
||||||
|
|
||||||
Tested and works great with the Aadafruit SGP30 Breakout Board
|
|
||||||
* http://www.adafruit.com/products/3709
|
|
||||||
|
|
||||||
This chip uses I2C to communicate, 2 pins are required to interface
|
|
||||||
|
|
||||||
Adafruit invests time and resources providing this open source code,
|
|
||||||
please support Adafruit and open-source hardware by purchasing
|
|
||||||
products from Adafruit!
