Introduction
We all want a computer that we can easily carry and use anywhere! That’s exactly when, six years ago, the market introduced a chip that can work wonders for engineers and learning programmers. Raspberry pi came into existence in the market, where programmers can learn programming, code small programmers in their computer and work with it as a full-fledged operating system.
This blog will give you insight into the cinder-raspberry Pi-2 Platform and details about Raspberry Pi.
What is Cinder?
Cinder, popularly known as OpenStack Block Storage. It is open-source software designed to manage and create a service that provides users with easy and consistent access to deployment. This enables the users to request and use the storage services without interfering the users with the information of API.
Cinder provides self-service to users and helps them in data storage to cloud computing applications.
What is Raspberry Pi and Why do we Use it?
Raspberry Pi is a small piece of the single-board computer developed by the Raspberry Pi Foundation in association with Broadcom in the United Kingdom. You can create your mini-computer by connecting the accessory like a mouse, keyboard, and display directly to Raspberry Pi.
It works slower than a computer and a laptop but performs all the features and functionality with minimum power consumption.
You use Raspberry Pi for programming languages, Image processing, IoT applications, building hardware/small software projects, video processing, and other applications.
Cinder with Raspberry Pi 2
Prerequisites
Below, we have the list of what we need before we start.
CMake 3.0
Raspbian Jessie or later
Clang 3.5.0+
CMake
Install the CMake by the below command:
sudo apt-get install cmake
Clang
It would be best if you built Cinder using the version of Clang(v3.5.0), a package for Raspbain Jessie. Using apt-get, install it.
sudo apt-get install clang
Download Clang for armv7a Linux for the Raspberry Pi 2.
When the below command gets a prompt, select /usr/bin/clang++ to set the clang as the default compiler.
sudo update-alternatives --config c++
You need to adjust the memory split of CPU/GPU when you want to use GCC instead of Clang. When you are building Cinder, the default settings for the memory crash will cause a hard crash.
Using the GCC 5.x on Raspberry Pi 2 Cinder has yet to be tested.
Dependencies for Cinder
Run the command mentioned below to install the Raspberry Pi 2 with its dependencies.
cd samples/BasicApp/proj/cmake
mkdir build && cd build
cmake .. -DCINDER_TARGET_GL=es2-rpi
make
Run
Start from samples/BasicApp/proj/cmake/build:
./Debug/BasicApp
Exit
To exit the BasicApp, hit the Esc key. Cinder for Linux has Esc hardcoded to exit an application on the Raspberry pi 2. However, it is important to return to the operating system.
In the future, you will have a better way to handle this issue.
Troubleshoot
Audio - Start the pulsedeamon
Install the pulse audio with raspbian ships. Before you use audio in your application, you need to start the pulsedeamon. Run the below command to use the audio:
pulseaudio -D
Audio–No Output Using a 3.5mm headphone jack
Try the below command, as it will force output to the 3.5mm jack
sudo amixer cset numid=3 1
