Does an LED Controller Support an SDK? Integrating Huidu and NovaStar
A developer asked whether one of our control cards supports the Huidu SDK, and which version. It is exactly the right question to ask before you build anything on top of an LED screen — because the controller, not the panel, is what your software talks to. Here is how SDK and API support actually works across the common control systems.
Short answer: yes, mainstream LED controllers expose an SDK or API, but the exact one and version depend on the specific control card and its firmware — so the useful thing is to match the controller to your integration goal.
The controller is the part you integrate with
An LED screen has two layers: the panels (which just display pixels) and the controller or control card (which receives content, schedules it and reports status). Any integration — a custom app, a CMS, remote control, an API call — happens through the controller. So “does it support an SDK?” is really a question about the control card model and firmware.
Huidu, NovaStar and the common ecosystems
The two control ecosystems we see most are Huidu and NovaStar, and both provide developer access:
- Huidu — control cards (the HD series) ship with player software and an SDK/protocol for pushing content and commands; the exact SDK build tracks the card model and firmware version.
- NovaStar — offers cloud and on-device integration (a publishing API and player SDKs on Taurus/COEX-class players) for content, scheduling and monitoring.
- Other open systems exist too; the principle is the same — an SDK or HTTP API sits on top of the controller.
What you can build with the SDK
Once you have the right controller and its SDK, typical integrations include:
- Push and update content (images, video, text) from your own app or backend.
- Schedule playlists and dayparts programmatically.
- Read status — online/offline, temperature, brightness — for monitoring.
- Control brightness, power and switching remotely or on a sensor.
How to get the exact answer for your project
Because SDK and version support is tied to the precise control card and firmware, the reliable way is to start from what you want to build. Tell us your integration goal — your own app, a CMS, an API, a particular SDK version — and the screen it will drive, and we recommend a controller that supports it and confirm the exact SDK/firmware it ships with. That way you are not reverse-engineering a card; you get one that fits your software from the start.

Frequently Asked Questions
Does the controller support the Huidu SDK?
Huidu control cards do provide an SDK/protocol for content and control, but the exact version is tied to the specific card model and firmware. Tell us your integration goal and we confirm the SDK/firmware on the controller we supply.
Does NovaStar have an API or SDK?
Yes — NovaStar offers cloud-publishing APIs and player SDKs (on Taurus/COEX-class players) for pushing content, scheduling and monitoring.
Can I integrate the screen with my own software or CMS?
Yes — through the controller’s SDK or HTTP API you can push content, schedule, and read status from your own app, backend or CMS. We match the controller to your software.
Can I control brightness and power programmatically?
Yes — most controller SDKs expose brightness, power, switching and monitoring, so you can automate them remotely or from a sensor.
Which controller should I choose for integration?
It depends on the SDK/API you want and the screen size. Tell us the integration goal and we recommend a controller that supports it out of the box, with its exact SDK and firmware.
