apa102-cppi

C++ Apa102 Library for Raspberry Pi

After doing a bit of research into rpi libraries to control apa102 leds, I found that other libraries were dependent on the now-deprecated WiringPi library. For this reason, I decided to create my own Apa102 library using pigpio, which has a simple and elegant interface, and, most importantly, is still actively maintained!

Getting set up:

Add this library to your project

• apa102-cppi is currently meant to be used as a static library, added to your project as a git submodule
• If you want to compile it as a shared library, then you will need to write your own makefile

Add as submodule

• To use this library as a git submodule, navigate to your own project folder (git repo) and enter:

$ git submodule add https://github.com/cosparks/apa102-cppi.git <folder>

• where <folder> is the relative path from the root of your repo

Build and Install PIGPIO

• If don't already have pigpio installed, run the package-installer script (this will install packages necessary to build and install pigpio)

$ cd scripts
$ sudo ./package-installer.sh

Run Tests (Optional)

• Open test/config.h the test folder and enter your led grid parameters
• Build and run the tests:

$ cd tests
$ make all
$ sudo test-grid
...
