This add-on is supported for MATLAB R2017a – R2018b.
This add-on library extends MATLAB Support Package for Arduino Hardware to control Adafruit NeoPixel LED strip. With this add-on, you can control the color and brightness of an RGB or RGBW NeoPixel strip to produce various lighting effects.
% Create arduino object with the add-on library
a = arduino('COM10', 'Uno', 'Libraries', 'Adafruit/NeoPixel');
% Create NeoPixel strip object with 30 pixels
sensor = addon(a, 'Adafruit/NeoPixel', 'D6', 30);
% Write colors to the first 20 pixels
writeColor(neostrip, 1:10, 'magenta', 11:20, 'yellow');
It includes the documentation and examples that demonstrate the use of the Adafruit NeoPixel addon.
Important: Before using this add-on library in MATLAB, you need to install the Adafruit NeoPixel Arduino library. Here are the instructions:
1. Download the zip file from https://github.com/adafruit/Adafruit_NeoPixel/archive/v1.1.2.zip
2. Unpackage the zip into local directory and rename the folder to ‘Adafruit_NeoPixel'.
3. Move the ‘Adafruit_NeoPixel’ folder into the "libraries" folder inside your Arduino sketchbook folder:
On Windows, the default path is "Documents\Arduino\libraries\"
On Mac, the default path is "~/Documents/Arduino/libraries/"
On Linux, the default path is "/home/<username>/Arduino/libraries"
1. After installing this add-on library and the required Arduino library, type "listArduinoLibraries" in MATLAB to see if the add-on is properly installed.
2. Wire up the Arduino board and the add-on device properly before creating the object to avoid a connection error in MATLAB.
3. Refer to the documentation for details on usage and syntax. It can be found under Supplemental Software in the product documentation.
