Silicon Labs (also known as “Chip Technology”) partner Ezurio has developed its EFR32BG24 (BG24) Bluetooth SoC for its Lyra 24 series of Bluetooth modules, and recently announced expanded support for the Canvas Software Suite (Canvas Software Suite) to help developers quickly and easily build low-power Bluetooth applications using embedded Python scripts, along with intuitive desktop … Read more
In current microcontrollers, many older models lack Bluetooth module functionality, while new microcontrollers (MCUs) with Bluetooth modules are rarely featured in existing textbooks. Thus, after researching some materials, this article presents a method to add Bluetooth functionality to standard MCU chips, effectively addressing the integration of older microcontroller models with new technologies. 1. The Necessity … Read more
2018 is referred to as the explosion period for NB-IoT commercialization in China. In the past year, the three major domestic operators have achieved almost full coverage of the NB-IoT network. In addition, 40% of global operators are actively deploying business applications, with about 5.5 million devices connecting to the Internet of Things (IoT) daily. … Read more
At the beginning of project development, we select chips that meet the design requirements. Among these, RAM determines the memory size during program execution, while ROM determines the storage space for applications. However, for projects with particularly large application functions, the internal FLASH (ROM) storage space of the MCU may not be sufficient. At this … Read more
The in-vehicle entertainment system, as the name suggests, originally aimed to provide entertainment experiences for drivers and passengers. However, with the advent of the smart cockpit era, the in-vehicle information and entertainment system has become a crucial medium for “human-vehicle-environment” interaction, serving as the center for tasks other than driving. Functionally, the in-vehicle entertainment system … Read more
