RT-Thread timely launches the first RT-Thread Nano Mini-Simplified Edition, suitable for 32-bit ARM entry-level MCUs used in home appliances, consumer electronics, medical equipment, industrial control, etc., supporting multi-tasking, semaphores and mailboxes. A relatively complete real-time operating system feature. Uses a minimum of memory resources to run on Cortex-M0 MCU as an example, the compiler, ROM and RAM MCU removed own needs, Nano ROM kernel occupies only 2.5KB, RAM is 1KB. RT-Thread has always been known for its high degree of flexibility and tailorability. At the time of the upcoming release of V3.0 IoT OS, in order to meet the strong demand for a large number of low-cost, entry-level MCUs for OS, the first RT-Thread Nano was launched in due course. Minimalist. The Nano version has been proven to be reliable and stable over a long period of time and has been officially recognized and supported by ARM Keil. From now on, users can get it directly from ARM Keil MDK's Pack Installer tool, which is easy to install and use. Very small memory resource usage RT-Thread Nano is a refined hard real-time kernel that supports relatively complete real-time operating system features such as multitasking, software timers, semaphores, mailboxes, and real-time scheduling. It also enables shell command lines to efficiently perform online dynamic debugging. The memory resource is very small. When running two threads (main thread + idle thread), the ROM and RAM still have a very small size. For example, running on the Cortex-M0 MCU, the size of the compiled ROM is 3.25KB, the size of the RAM is 1.04KB, except for the ROM and RAM required by the MCU itself, the ROM of the RT-Thread Nano core is only 2.5KB, and the RAM is 1KB. It is worth mentioning that the RT-Thread Nano version and the RT-Thread standard version are identical in the kernel API, and are advanced features for future complex projects such as file system data storage, IoT network applications and even graphical user interfaces and multimedia interactions. Provide a smooth transition. Easy and fast installation and deployment Currently, the RT-Thread Nano version is available as a Keil MDK pack and is distributed on the official website of ARM Keil. Users can easily obtain the latest RT-Thread Nano version through the Pack Installer tool provided by Keil MDK, and deploy it to the local system through Run-TIme Environment, which makes RT-Thread Nano and MDK perfectly integrated, eliminating the need for manual porting. trouble. In the Keil MDK project, you can also add the rt-thread::shell component, so the project can also support the command line features, making the hardware firmware a tangible system, and the development of the product becomes easier. easy! Suitable for 32 -bit ARM entry-level MCUs RT-Thread Nano is suitable for 32-bit ARM entry-level MCUs used in home appliances, consumer electronics, medical equipment, industrial control and other fields. In fact, from the market pressure, strict requirements are placed on product launch time, system stability and maintainability of software code. Many applications in such environments have strong demand for RTOS. However, due to the lack of resource-intensive, fully-product-proven and simple-to-deploy RTOSs on the market, many customers have to abandon RTOS and switch to bare-metal for development, which increases development difficulty and limits system size. , ultimately affecting the time to market of the product. The emergence of Nano provides RTOS options for such resource-constrained systems, which makes it possible to enjoy the benefits of multitasking, real-time, program efficiency, and ease of maintenance. In the future, RT-Thread will launch similar small-size and customized kernel versions for other CPU architectures and compiler tools, satisfying the different needs of different chips and different vendors, fulfilling its constant innovation and focusing on the ultimate, in order to continuously improve domestic embedded. And the commitment of the IoT industry software capabilities to make unremitting efforts!
