RT-Thread
RT-Thread is an open-source real-time operating system (RTOS) for Embedded devices and Internet of things (IoT).[1][2] It is developed by the RT-Thread Development Team based in China. RT-Thread is aimed to change the current situation in China that there is no well used open-source real-time operating system in the microcontroller area.

Overview
RT-Thread was started in 2006 as an open-source real-time operating system (RTOS) that is mainly written in C language. There are two types of RT-Thread: Standard and Nano. For resource-constrained microcontrollers, RT-Thread Nano was released in 2017 and requires a minimum of 3KB Flash/ROM and 1.2KB RAM.[1][2]
