IntroductionIn the previous article (Getting Started with Zephyr: Saving Data to Files), I demonstrated how to create an application using the Zephyr project RTOS to store data on a microSD card. A microSD card allows embedded systems to store large amounts of data. When there is no internet connection or the cost of frequent data … Read more
Introduction In the previous two articles (Getting Started with Zephyr: Devicetrees and Getting Started with Zephyr: Devicetree Bindings), I demonstrated the “Devicetree” in the Zephyr Project real-time operating system. Through the Devicetree, we can describe the hardware in the system to the operating system. As mentioned in the first article, Zephyr supports many popular System-on-Chip … Read more
Sun Zhongjie （Nanjing Silan Microelectronics Technology Co., Ltd.，Jiangsu Nanjing 210042） Abstract：In recent years，how to reasonably use multiple rates for communication in BLE has received wide attention， but most studies focus on performance optimization at a single communication rate， which has a certain impact on the throughput of BLE device systems。To address these issues， a RSSI … Read more
I believe the cross-platform abstraction provided by ZephyrRTOS is a very important feature. Of course, the abstraction itself also brings a more complex software architecture and a steeper learning curve. Recently, I tried to use the nRF52840 to create a low-power Bluetooth + LTE + GNSS board. Initially, the distributor lent me an nRF52840 DK, … Read more
In the fields of Internet of Things (IoT) and wireless communication, Nordic Semiconductor has always been a pioneer of innovation. Today, we will delve into Nordic Semiconductor’s flagship product – the NRF52840-QIAA-R, a multifunctional system-on-chip (SoC) that will redefine the possibilities of wireless communication. What is NRF52840-QIAA-R? The NRF52840-QIAA-R is a high-performance, multiprotocol wireless SoC … Read more
