VxWorks UART Programming: Serial Port Configuration and I/O

UART (Universal Asynchronous Receiver/Transmitter) remains a fundamental interface for debugging, control, and device communication in embedded systems. While the programming model is broadly consistent across operating systems, VxWorks exposes UART functionality through its I/O system and ioctl interface.

1. Introduction: Empowering Intelligent Systems with Computer Vision on VxWorks

The convergence of machine learning and artificial intelligence (AI) is reshaping industries, driving innovation and automation. At the heart of this transformation lies machine learning, a pivotal subset of AI that enables applications to learn from data and refine their performance without explicit, rule-based programming. A significant modality for data acquisition in intelligent systems is through visual input, where images provide a wealth of information about the environment. Computer vision, a field dedicated to replicating human visual capabilities in machines, plays a crucial role in interpreting and understanding this visual data using advanced computer software and hardware.

Debugging VxWorks Semaphores

By: Brian Kuhl

When it comes down to debugging semaphore interactions it can be a tricky problem. As when there is a deadlock or weird delay because of excessive priority inheritance, it is never just one mutex semaphore, but often the unintended interaction of several semaphores in multiple tasks.

Demonstration of Precision Time Protocol in VxWorks

Mon, 01 Aug 2016 10:12:54 +0800

An industrial system can consist of hundreds of sensors, motors and controllers. When the physical infrastructure connecting them together is an Ethernet network, it takes special handling to make sure that sensor data and control commands reach their destinations in the network within a hard time limit, often within 1 or 2µs. Failure for a message to reach its destination in time can result in uncoordinated mechanical movements, or wrong correlation of sensor data.

Introduction to VxWorks 5.5 Programming
