LiteOS
Huawei LiteOS was a lightweight real-time operating system (RTOS) developed by Huawei. It is an open source, POSIX compliant operating system for Internet of things (IoT) devices, released under a three-clause BSD license. Microcontrollers of different architectures such as ARM (M0/3/4/7, A7/17/53, ARM9/11), x86, and RISC-V are supported by the project. Huawei LiteOS is part of Huawei's '1+8+N' Internet of Things solution, and has been featured in a number of open source development kits and industry offerings. Smartwatches by Huawei and its former Honor brand run LiteOS. LiteOS has since been incorporated into the IoT-oriented HarmonyOS with open source OpenHarmony. History On 20 May 2015, at the Huawei Network Conference, Huawei proposed the '1+2+1' Internet of Things solution and release the IoT operating system named Huawei LiteOS. Key features *Lightweight, small kernel; <10 |

HarmonyOS
HarmonyOS (HMOS) () is a distributed operating system developed by Huawei to collaborate and interconnect with multiple smart devices on the Internet of Things (IoT) ecosystem. In its current multi-kernel design, the operating system selects suitable kernels from the abstraction layer for devices with diverse resources. For IoT devices, the system is known to be based on LiteOS kernel; while for smartphones and tablets, it is based on a Linux kernel layer with AOSP compatibility libraries to support legacy APK apps, in addition to native HarmonyOS HAP apps via the Ark Compiler. The system includes a communication base DSoftBus for integrating physically separate devices into a virtual Super Device, allowing one device to control others and sharing data among devices with distributed communication capabilities. It supports several forms of apps, including the apps that can be installed from AppGallery on smartphones and tablets, installation-free Quick apps and lightweig ...

OpenHarmony
OpenAtom OpenHarmony, or abbreviated as OpenHarmony (OHOS), is an open-source version of HarmonyOS donated by Huawei to the OpenAtom Foundation. Similar to HarmonyOS, the open-source operating system is designed with a layered architecture, which consists of four layers from the bottom to the top, i.e., the kernel layer, system service layer, framework layer, and application layer. OpenHarmony supports various devices running a mini system such as printers, speakers, smartwatches and any other smart device with memory as small as 128 KB, or running a standard system with memory greater than 128 MB. The system contains the basic capabilities of HarmonyOS. History The first version of OpenHarmony was launched by the OpenAtom Foundation on September 10, 2019 after receiving a donation of the open-source code from Huawei, with support for devices with RAM volumes ranging from 128 KB to 128 MB. The OpenHarmony 2.0 (Canary version) was launched in June 2021, supporting a variety ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smartwatches
A smartwatch is a wearable computer in the form of a watch; modern smartwatches provide a local touchscreen interface for daily use, while an associated smartphone app provides management and telemetry, such as long-term biomonitoring. While early models could perform basic tasks, such as calculations, digital time telling, translations, and game-playing, smartwatches released since 2015 have more general functionality closer to smartphones, including mobile apps, a mobile operating system and WiFi/Bluetooth connectivity. Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth headset. Some models, called watch phones (or phone watches), have mobile cellular functionality such as making telephone calls. While internal hardware varies, most have an electronic visual display, either backlit LCD or OLED. Some use transflective or electronic paper, to consume less power. They are usually powered by a re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
