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
|
||||

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.

Everyone is permitted to copy and distribute verbatim copies
|

of this license document, but changing it is not allowed.
|
||||
|
||||
|
||||
This version of the GNU Lesser General Public License incorporates
|
||||
the terms and conditions of version 3 of the GNU General Public
|
||||
License, supplemented by the additional permissions listed below.
|
||||
|
||||
0. Additional Definitions.
|
||||
|
||||
As used herein, "this License" refers to version 3 of the GNU Lesser
|
||||
General Public License, and the "GNU GPL" refers to version 3 of the GNU
|
||||
General Public License.
|
||||
|
||||
"The Library" refers to a covered work governed by this License,
|
||||
other than an Application or a Combined Work as defined below.
|
||||
|
||||
An "Application" is any work that makes use of an interface provided
|
||||
by the Library, but which is not otherwise based on the Library.
|
||||
Defining a subclass of a class defined by the Library is deemed a mode
|
||||
of using an interface provided by the Library.
|
||||
|
||||
A "Combined Work" is a work produced by combining or linking an
|
||||
Application with the Library. The particular version of the Library
|
||||
with which the Combined Work was made is also called the "Linked
|
||||
Version".
|
||||
|
||||
The "Minimal Corresponding Source" for a Combined Work means the
|
||||
Corresponding Source for the Combined Work, excluding any source code
|
||||
for portions of the Combined Work that, considered in isolation, are
|
||||
based on the Application, and not on the Linked Version.
|
||||
|
||||
The "Corresponding Application Code" for a Combined Work means the
|
||||
object code and/or source code for the Application, including any data
|
||||
and utility programs needed for reproducing the Combined Work from the
|
||||
Application, but excluding the System Libraries of the Combined Work.
|
||||
|
||||
1. Exception to Section 3 of the GNU GPL.
|
||||
|
||||
You may convey a covered work under sections 3 and 4 of this License
|
||||
without being bound by section 3 of the GNU GPL.
|
||||
|
||||
2. Conveying Modified Versions.
|
||||
|
||||
If you modify a copy of the Library, and, in your modifications, a
|
||||
facility refers to a function or data to be supplied by an Application
|
||||
that uses the facility (other than as an argument passed when the
|
||||
facility is invoked), then you may convey a copy of the modified
|
||||
version:
|
||||
|
||||
a) under this License, provided that you make a good faith effort to
|
||||
ensure that, in the event an Application does not supply the
|
||||
function or data, the facility still operates, and performs
|
||||
whatever part of its purpose remains meaningful, or
|
||||
|
||||
b) under the GNU GPL, with none of the additional permissions of
|
||||
this License applicable to that copy.
|
||||
|
||||
3. Object Code Incorporating Material from Library Header Files.
|
||||
|
||||
The object code form of an Application may incorporate material from
|
||||
a header file that is part of the Library. You may convey such object
|
||||
code under terms of your choice, provided that, if the incorporated
|
||||
material is not limited to numerical parameters, data structure
|
||||
layouts and accessors, or small macros, inline functions and templates
|
||||
(ten or fewer lines in length), you do both of the following:
|
||||
|
||||
a) Give prominent notice with each copy of the object code that the
|
||||
Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the object code with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
4. Combined Works.
|
||||
|
||||
You may convey a Combined Work under terms of your choice that,
|
||||
taken together, effectively do not restrict modification of the
|
||||
portions of the Library contained in the Combined Work and reverse
|
||||
engineering for debugging such modifications, if you also do each of
|
||||
the following:
|
||||
|
||||
a) Give prominent notice with each copy of the Combined Work that
|
||||
the Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the Combined Work with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
c) For a Combined Work that displays copyright notices during
|
||||
execution, include the copyright notice for the Library among
|
||||
these notices, as well as a reference directing the user to the
|
||||
copies of the GNU GPL and this license document.
|
||||
|
||||
d) Do one of the following:
|
||||
|
||||
0) Convey the Minimal Corresponding Source under the terms of this
|
||||
License, and the Corresponding Application Code in a form
|
||||
suitable for, and under terms that permit, the user to
|
||||
recombine or relink the Application with a modified version of
|
||||
the Linked Version to produce a modified Combined Work, in the
|
||||
manner specified by section 6 of the GNU GPL for conveying
|
||||
Corresponding Source.
|
||||
|
||||
1) Use a suitable shared library mechanism for linking with the
|
||||
Library. A suitable mechanism is one that (a) uses at run time
|
||||
a copy of the Library already present on the user's computer
|
||||
system, and (b) will operate properly with a modified version
|
||||
of the Library that is interface-compatible with the Linked
|
||||
Version.
|
||||
|
||||
e) Provide Installation Information, but only if you would otherwise
|
||||
be required to provide such information under section 6 of the
|
||||
GNU GPL, and only to the extent that such information is
|
||||
necessary to install and execute a modified version of the
|
||||
Combined Work produced by recombining or relinking the
|
||||
Application with a modified version of the Linked Version. (If
|
||||
you use option 4d0, the Installation Information must accompany
|
||||
the Minimal Corresponding Source and Corresponding Application
|
||||
Code. If you use option 4d1, you must provide the Installation
|
||||
Information in the manner specified by section 6 of the GNU GPL
|
||||
for conveying Corresponding Source.)
|
||||
|
||||
5. Combined Libraries.
|
||||
|
||||
You may place library facilities that are a work based on the
|
||||
Library side by side in a single library together with other library
|
||||
facilities that are not Applications and are not covered by this

of the GNU Lesser General Public License from time to time. Such new

versions will be similar in spirit to the present version, but may

differ in detail to address new problems or concerns.
|

Each version is given a distinguishing version number. If the
|

Library as you received it specifies that a certain numbered version
|

of the GNU Lesser General Public License "or any later version"
|
||||
applies to it, you have the option of following the terms and

conditions either of that published version or of any later version
|

published by the Free Software Foundation. If the Library as you

received it does not specify a version number of the GNU Lesser
|
||||
General Public License, you may choose any version of the GNU Lesser
|
||||
General Public License ever published by the Free Software Foundation.
|
||||
|
||||
If the Library as you received it specifies that a proxy can decide
|
||||
whether future versions of the GNU Lesser General Public License shall
|
||||
apply, that proxy's public statement of acceptance of any version is
|
||||
permanent authorization for you to choose that version for the

Library.
