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 Python/Raspberry Pi projects check these very common issues to ensure they don't apply**: - - - If you are receiving an **ImportError: No module named...** error then a - library the code depends on is not installed. Check the tutorial/guide or - README to ensure you have installed the necessary libraries. Usually the - missing library can be installed with the `pip` tool, but check the tutorial/guide - for the exact command. - - - **Be sure you are supplying adequate power to the board.** Check the specs of - your board and power 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. - -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: - -- Platform/operating system (i.e. Raspberry Pi with Raspbian operating system, - Windows 32-bit, Windows 64-bit, Mac OSX 64-bit, etc.): **INSERT PLATFORM/OPERATING - SYSTEM HERE** - -- Python version (run `python -version` or `python3 -version`): **INSERT PYTHON - VERSION HERE** - -- Error message you are receiving, including any Python exception traces: **INSERT - ERROR MESAGE/EXCEPTION TRACES HERE*** - -- List the steps to reproduce the problem below (if possible attach code or commands - to run): **LIST REPRO STEPS BELOW** diff --git a/Adafruit_Python_CharLCD/.github/PULL_REQUEST_TEMPLATE.md b/Adafruit_Python_CharLCD/.github/PULL_REQUEST_TEMPLATE.md deleted file mode 100644 index 7b641eb..0000000 --- a/Adafruit_Python_CharLCD/.github/PULL_REQUEST_TEMPLATE.md +++ /dev/null @@ -1,26 +0,0 @@ -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!
