Why RT-Thread?

Rich Components

Device virtual file system
Supports FAT, UFFS, NFSv3, ROMFS, RAMFS, etc.
Device management framework
Uses a unified interface to access the hardware peripherals.
Low power management framework
The system can go to sleep mode automatically, and supports dynamic voltage and frequency scaling.
Hardware encryption &decryption framework
Supports algorithms such as hash, symmetric, gcm, etc.
Protocol stack
Supports Ethernet, Wi-Fi, Bluetooth, NB-IoT, 2G | 3G | 4G, Http, MQTT, and LwM2M, etc.
Remote upgrade FOTA
Safe and reliable, and which supports encryption, anti-tampering, breakpoint resume, intelligent restoration, backtracking and other mechanisms.
Dynamic modules
The dynamic modules and the kernel can be compiled separately, and at runtime, the compiled dynamic modules are loaded into the kernel to run.
Third-party components
Support Yaffs2, Sqlite, FreeModbus, Canopen, etc.

Great Portability & Software Ecology

Supports mainstream chip architecture
Such as ARM Cortex-M, MIPS, X86, Xtensa, C-Sky, RISC-V, ARC, etc.
Unified interface specification
Various MCUs and their peripheral interfaces are highly abstracted and the programming interfaces are unified.
POSIX interface
Easy to port Linux or Unix programs to RT-Thread. Support for File I/O, Signals, PThreads, IPC, etc.
Seamless application migration
Follows highly reusable software design principles, one-time programming, permanent use.
Multiple compiling tools
Such as Keil, IAR, GCC, Eclipse, Visual Studio and RT-Thread Studio development environment, etc.
Rich BSPs and porting templates
Lots of BSPs as well as porting templates that can be quickly ported to the target chip based on the porting template.

Tiny & Elegant

Small in Size
RT-Thread has a Nano version with a very small size and refined hard real-time kernel, which requires only 3KB of ROM and 1.2 KB of RAM.
Feature-rich
RT-Thread has rich features, such as, hard real-time scheduler, thread management, interthread synchronization and communication, clock management, interrupt management, memory management, etc.

RT-Thread Studio

RT-Thread studio is one-stop development tool, it has easy-to-use graphical configuration system and a wealth of software packages and components resources, which makes IoT development simple and efficient.

  • Community version is free forever.
  • Easy-to-use engineering creation wizard can quickly validate prototypes.
  • Brand new graphical configuration system, which supports both schema diagram and tree diagram configuration.
  • Software package market offers a variety of package resources.

RT-Thread IoT OS Hopes to Get Connect with Global Developers:
Alan Kay said:“Simple things should be simple, complex things should be possible”. This sentence was the inspiration for the founder of RT-Thread to stick to his beliefs. RT-Thread is an open source embedded real-time operating system, and this project started in 2006. I know you have no idea what RT-Thread is, but you are using an IoT OS system now, that’s where this article may be of interest. Let’s take a quick tour of RT-Thread.

RT-Thread IoT OS Nano Version Introduction:
RT-Thread has standard version and Nano version, the standard version consisting of kernel layer, components and service layer, and IoT framework layer. The Nano version with a very small size and refined hard real-time kernel, which is very suited for the resource-constrained micro controller unit (MCU) system. This article would go into detail about the Nano version of RT-Thread.
