Example tutorial
We have carefully produced a wealth of sample tutorials, covering audio and video input and output, audio and video codec, screenshots, streaming, recording, video mixing, special effects overlay, USB camera, GPIO operation, power management, touch screen operation, OLED screen control, etc. Links to help you remove all the problems that may be encountered in the product development process. We will continue to update sample projects and tutorials.
LinkSVP
In order to facilitate users to develop products in the field of machine vision and AI, we have developed the LinkSVP framework to simplify the upstream and downstream development process and allow developers to focus on core algorithms. At the same time, several sample programs have been made to help users easily get started. Even in the scheme with NNIE unit, we provide tools for the acceleration of embedded optimization and can also run deep learning algorithms.
Development environment
We have cross-compiled common third-party libraries and placed them in the virtual machine to facilitate user development and use.
Development framework: QT5
Media related: ffmpeg, fdkaac, lame, alsa
WEB development: php, nginx (nginx-rtmp+http-flv)
Network related: iperf, ppp, wpa, hostap, iw, libnl, ssl
Graphics processing: Opencv, NCNN
Others: freetype, icu, libts, zlib, libxml...
Open source software
In order to demonstrate the basic capabilities of the evaluation board so that users can fully evaluate the solution before starting to develop it, we have produced an "encoder system" that demonstrates all the interface capabilities and codec performance of the solution in the form of a universal encoder. The product is completely open source, including main program source code, file system, webpage source code, etc.
If the user's target product is similar to the open source product, it can be modified directly on the basis of the product source code.
Development model
The product can be developed directly using the official HiSilicon SDK, and the core hardware is fully compatible. It can directly use the official kernel, uboot, etc., without modifying any line of code.
On this basis, LinkPi provides a faster and more convenient LinkSDK, which not only reduces the difficulty of learning, but also provides richer extended functions.
Technical Support
We will assign professional engineers to provide you with one-to-one technical support. The technical support team is composed of engineers with rich industry experience, and will do our best to answer all possible problems you may encounter in all aspects of the product development process.
