Introduction Device driver development is at the core of embedded systems. In the industry-leading real-time operating system (RTOS) VxWorks, hardware drivers are implemented using the VxBus framework. This guide will provide a comprehensive overview of VxBus driver development, covering all aspects from architecture to practical implementation. Whether you are a newcomer to VxWorks 7 or … Read more
1. Introduction The Inter-Integrated Circuit (I²C) is a widely used low-speed, two-wire communication protocol designed for communication between integrated circuits. In embedded systems, I²C is commonly used to connect sensors, EEPROMs, ADCs, and other peripherals. [VxWorks 7] introduces a modern, scalable, and modular driver framework built on VxBus, supporting dynamic driver registration, device tree integration, … Read more
Introduction In industrial control, data acquisition, and communication scenarios, PLX (acquired by Broadcom) PCIe controller chips are widely used. VxWorks 7, as the latest generation of real-time operating systems from Wind River, offers a more modern driver framework – VxBus 2.0. This article will share the complete process of developing PCIe device drivers in the … Read more
