# Contribution Guidelines
|
||||
|
||||
This library is the culmination of the expertise of many members of the open source community who have dedicated their time and hard work. The best way to ask for help or propose a new idea is to [create a new issue](https://github.com/adafruit/Adafruit_NeoPixel/issues/new) while creating a Pull Request with your code changes allows you to share your own innovations with the rest of the community.
|
||||
|
||||
The following are some guidelines to observe when creating issues or PRs:
|
||||
|
||||
- Be friendly; it is important that we can all enjoy a safe space as we are all working on the same project and it is okay for people to have different ideas
|
||||
|
||||
- [Use code blocks](https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#code); it helps us help you when we can read your code! On that note also refrain from pasting more than 30 lines of code in a post, instead [create a gist](https://gist.github.com/) if you need to share large snippets
|
||||
|
||||
- Use reasonable titles; refrain from using overly long or capitalized titles as they are usually annoying and do little to encourage others to help :smile:
|
||||
|
||||
- Be detailed; refrain from mentioning code problems without sharing your source code and always give information regarding your board and version of the library

## Installation
|
||||
|
||||
### First Method
|
||||
|
||||
|
||||
|
||||
1. In the Arduino IDE, navigate to Sketch > Include Library > Manage Libraries
|
||||
1. Then the Library Manager will open and you will find a list of libraries that are already installed or ready for installation.
|
||||
1. Then search for Neopixel strip using the search bar.
|
||||
1. Click on the text area and then select the specific version and install it.
|
||||
|
||||
### Second Method
|
||||
|
||||
1. Navigate to the [Releases page](https://github.com/adafruit/Adafruit_NeoPixel/releases).
|
||||
1. Download the latest release.
|
||||
1. Extract the zip file
|
||||
1. In the Arduino IDE, navigate to Sketch > Include Library > Add .ZIP Library
|
||||
|
||||
## Features
|
||||
|
||||
- ### Simple to use
|
||||
|
||||
Controlling NeoPixels “from scratch” is quite a challenge, so we provide a library letting you focus on the fun and interesting bits.
|
||||
|
||||
- ### Give back
|
||||
|
||||
The library is free; you don’t have to pay for anything. Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!
|
||||
|
||||
- ### Supported Chipsets
|
||||
|
||||
We have included code for the following chips - sometimes these break for exciting reasons that we can't control in which case please open an issue!
|
||||
|
||||
- AVR ATmega and ATtiny (any 8-bit) - 8 MHz, 12 MHz and 16 MHz
|
||||
- Teensy 3.x and LC
|
||||
- Arduino Due
|
||||
- Arduino 101
|
||||
- ATSAMD21 (Arduino Zero/M0 and other SAMD21 boards) @ 48 MHz
|
||||
- ATSAMD51 @ 120 MHz
|
||||
- Adafruit STM32 Feather @ 120 MHz
|
||||
- ESP8266 any speed
|
||||
- ESP32 any speed
|
||||
- Nordic nRF52 (Adafruit Feather nRF52), nRF51 (micro:bit)
|
||||

### Roadmap
|
||||
|
||||
The PRIME DIRECTIVE is to maintain backward compatibility with existing Arduino sketches -- many are hosted elsewhere and don't track changes here, some are in print and can never be changed!
|
||||
|
||||
Please don't reformat code for the sake of reformatting code. The resulting large "visual diff" makes it impossible to untangle actual bug fixes from merely rearranged lines. (Exception for first item in wishlist below.)
|
||||
|
||||
Things I'd Like To Do But There's No Official Timeline So Please Don't Count On Any Of This Ever Being Canonical:
|
||||
|
||||
- For the show() function (with all the delicate pixel timing stuff), break out each architecture into separate source files rather than the current unmaintainable tangle of #ifdef statements!
|
||||
- Please don't use updateLength() or updateType() in new code. They should not have been implemented this way (use the C++ 'new' operator with the regular constructor instead) and are only sticking around because of the Prime Directive. setPin() is OK for now though, it's a trick we can use to 'recycle' pixel memory across multiple strips.
|
||||
- In the M0 and M4 code, use the hardware systick counter for bit timing rather than hand-tweaked NOPs (a temporary kludge at the time because I wasn't reading systick correctly). (As of 1.4.2, systick is used on M4 devices and it appears to be overclock-compatible. Not for M0 yet, which is why this item is still here.)
|
||||
- As currently written, brightness scaling is still a "destructive" operation -- pixel values are altered in RAM and the original value as set can't be accurately read back, only approximated, which has been confusing and frustrating to users. It was done this way at the time because NeoPixel timing is strict, AVR microcontrollers (all we had at the time) are limited, and assembly language is hard. All the 32-bit architectures should have no problem handling nondestructive brightness scaling -- calculating each byte immediately before it's sent out the wire, maintaining the original set value in RAM -- the work just hasn't been done. There's a fair chance even the AVR code could manage it with some intense focus. (The DotStar library achieves nondestructive brightness scaling because it doesn't have to manage data timing so carefully...every architecture, even ATtiny, just takes whatever cycles it needs for the multiply/shift operations.)

/****************************************************************************
|
||||
* This example was developed by the Hackerspace San Salvador to demonstrate
|
||||
* the simultaneous use of the NeoPixel library and the Bluetooth SoftDevice.
|
||||
* To compile this example you'll need to add support for the NRF52 based
|
||||
* following the instructions at:
|
||||
* https://github.com/sandeepmistry/arduino-nRF5
|
||||
* Or adding the following URL to the board manager URLs on Arduino preferences:
|
||||
* https://sandeepmistry.github.io/arduino-nRF5/package_nRF5_boards_index.json
|
||||
* Then you can install the BLEPeripheral library avaiable at:
|
||||
* https://github.com/sandeepmistry/arduino-BLEPeripheral
|
||||
* To test it, compile this example and use the UART module from the nRF
|
||||
* Toolbox App for Android. Edit the interface and send the characters
|
||||
* 'a' to 'i' to switch the animation.
|
||||
* There is a delay because this example blocks the thread of execution but
|
||||
* the change will be shown after the current animation ends. (This might
|
||||
* take a couple of seconds)
|
||||
* For more info write us at: info _at- teubi.co
