To 2 | improve the speed of resolution please review the following guidelines and 3 | common troubleshooting steps below before creating the issue: 4 | 5 | - **Do not use GitHub issues for troubleshooting projects and issues.** Instead use 6 | the forums at http://forums.adafruit.com to ask questions and troubleshoot why 7 | something isn't working as expected. In many cases the problem is a common issue 8 | that you will more quickly receive help from the forum community. GitHub issues 9 | are meant for known defects in the code. If you don't know if there is a defect 10 | in the code then start with troubleshooting on the forum first. 11 | 12 | - **If following a tutorial or guide be sure you didn't miss a step.** Carefully 13 | check all of the steps and commands to run have been followed. Consult the 14 | forum if you're unsure or have questions about steps in a guide/tutorial. 15 | 16 | - **For Python/Raspberry Pi projects check these very common issues to ensure they don't apply**: 17 | 18 | - If you are receiving an **ImportError: No module named...** error then a 19 | library the code depends on is not installed. Check the tutorial/guide or 20 | README to ensure you have installed the necessary libraries. Usually the 21 | missing library can be installed with the `pip` tool, but check the tutorial/guide 22 | for the exact command. 23 | 24 | - **Be sure you are supplying adequate power to the board.** Check the specs of 25 | your board and power in an external power supply. In many cases just 26 | plugging a board into your computer is not enough to power it and other 27 | peripherals. 28 | 29 | - **Double check all soldering joints and connections.** Flakey connections 30 | 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. 31 | 32 | If you're sure this issue is a defect in the code and checked the steps above 33 | please fill in the following fields to provide enough troubleshooting information. 34 | You may delete the guideline and text above to just leave the following details: 35 | 36 | - Platform/operating system (i.e. Raspberry Pi with Raspbian operating system, 37 | Windows 32-bit, Windows 64-bit, Mac OSX 64-bit, etc.): **INSERT PLATFORM/OPERATING 38 | SYSTEM HERE** 39 | 40 | - Python version (run `python -version` or `python3 -version`): **INSERT PYTHON 41 | VERSION HERE** 42 | 43 | - Error message you are receiving, including any Python exception traces: **INSERT 44 | ERROR MESAGE/EXCEPTION TRACES HERE*** 45 | 46 | - List the steps to reproduce the problem below (if possible attach code or commands 47 | to run): **LIST REPRO STEPS BELOW** 48 | -------------------------------------------------------------------------------- /.github/PULL_REQUEST_TEMPLATE.md: -------------------------------------------------------------------------------- 1 | Thank you for creating a pull request to contribute to Adafruit's GitHub code! 2 | Before you open the request please review the following guidelines and tips to 3 | help it be more easily integrated: 4 | 5 | - **Describe the scope of your change--i.e. what the change does and what parts 6 | of the code were modified.** This will help us understand any risks of integrating 7 | the code. 8 | 9 | - **Describe any known limitations with your change.** For example if the change 10 | doesn't apply to a supported platform of the library please mention it. 11 | 12 | - **Please run any tests or examples that can exercise your modified code.** We 13 | strive to not break users of the code and running tests/examples helps with this 14 | process. 15 | 16 | Thank you again for contributing! We will try to test and integrate the change 17 | as soon as we can, but be aware we have many GitHub repositories to manage and 18 | can't immediately respond to every request. There is no need to bump or check in 19 | on a pull request (it will clutter the discussion of the request). 20 | 21 | Also don't be worried if the request is closed or not integrated--sometimes the 22 | priorities of Adafruit's GitHub code (education, ease of use) might not match the 23 | priorities of the pull request. Don't fret, the open source community thrives on 24 | forks and GitHub makes it easy to keep your changes in a forked repo. 25 | 26 | After reviewing the guidelines above you can delete this text from the pull request. 27 | -------------------------------------------------------------------------------- /.gitignore: -------------------------------------------------------------------------------- 1 | build/ 2 | dist/ 3 | *.egg-info 4 | *.pyc 5 | -------------------------------------------------------------------------------- /Adafruit_MCP9808/MCP9808.py: -------------------------------------------------------------------------------- 1 | # Copyright (c) 2014 Adafruit Industries 2 | # Author: Tony DiCola 3 | # 4 | # Permission is hereby granted, free of charge, to any person obtaining a copy 5 | # of this software and associated documentation files (the "Software"), to deal 6 | # in the Software without restriction, including without limitation the rights 7 | # to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 8 | # copies of the Software, and to permit persons to whom the Software is 9 | # furnished to do so, subject to the following conditions: 10 | # 11 | # The above copyright notice and this permission notice shall be included in 12 | # all copies or substantial portions of the Software. 13 | # 14 | # THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 15 | # IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 16 | # FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
