Selected from TI Wireless Connectivity Forum, original post link at the bottom “Read Original” 0 Introduction In recent years, wireless sensor network technology has developed rapidly. Due to the free and open characteristics of the 2.4 GHz communication band, various communication protocols based on this band, such as Wi-Fi and Bluetooth, have matured and been … Read more
Does IIC support hot swapping? (With a detailed interpretation of CW32 IIC protocol) Have you learned it yet? After I finish these low-speed experiments, I will provide the debugging steps for the logic analyzer. IIC is done, next comes SPI, which is worth highlighting because the vast majority of devices use SPI; it’s practically ALL … Read more
01 【Introduction】 SPI: Serial Peripheral Interface, is a synchronous serial interface for device communication. SPI was developed by Motorola around 1985 and is suitable for short-distance, device-to-device communication. Since then, this interface has become a de facto standard adopted by many semiconductor manufacturers, especially microcontrollers (MCUs) and microprocessors (MPUs). 02 【SPI Interface】 The SPI bus … Read more
1. Introduction UART, full name Universal Asynchronous Receiver/Transmitter, translated as Universal Asynchronous Transceiver. The emergence of serial ports was around 1980, with data transmission rates of 115kbps～ 230kbps. Initially, serial ports were used to connect computer peripherals, typically connecting mice, external Modems, and old cameras and graphics tablets. Serial ports can also be used for … Read more
Since the launch of the world’s first MCU based on the Arm Cortex-M architecture in 2007, STM32 has gradually become the favorite platform for embedded engineers, achieving the top market share in China’s MCU market in 2018. In response to the market trend of increasing intelligence and the integration of AI in cloud-edge-end systems for … Read more
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
