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.

This is an Arduino library for the DHT series of low cost temperature/humidity sensors.
|
||||
|
||||
Tutorial: https://learn.adafruit.com/dht
|
||||
|
||||
To download. click the DOWNLOADS button in the top right corner, rename the uncompressed folder DHT. Check that the DHT folder contains DHT.cpp and DHT.h. Place the DHT library folder your <arduinosketchfolder>/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE.

# Adafruit DHT Humidity & Temperature Unified Sensor Library
|
||||
|
||||
This library also includes an optional class for the
|
||||
[DHT humidity and temperature sensor](https://learn.adafruit.com/dht/overview)
|
||||
which is designed to work with the [Adafruit unified sensor library](https://learn.adafruit.com/using-the-adafruit-unified-sensor-driver/introduction).
|
||||
|
||||
You must have the following Arduino libraries installed to use this class:

Arduino compatibility example
|
||||
=============================
|
||||
|
||||
This example shows that it is now possible to re-use arduino sketches in
|
||||
Contiki. This example documents the necessary magic. Arduino specifies
|
||||
two routines, `setup` and `loop`. Before `setup` is called, the
|
||||
framework initializes hardware. In original Arduino, all this is done in
|
||||
a `main` function (in C). For contiki we define a process that does the
|
||||
same.
|
||||
|
||||
See the documentation file in apps/contiki-compat/README.md
