A New Perspective on Improvements in Event and Time Triggered Embedded Programming

1. Limitations of Traditional Programming Structures When not using an RTOS, embedded software typically employs two traditional programming structures: one is called the “foreground-background structure” or “super loop structure,” which is essentially an event-triggered programming method, and the other is a time-triggered programming method, as described in Michael J. Pont’s “Time-Triggered Programming Model.” In practical … Read more

Embedded Programming Model | Observer Pattern

Hello everyone, I am the Mixed Content Master. This time we share a commonly used concept/programming model in embedded systems—the Observer Pattern. Overview of the Observer Pattern The Observer Pattern is a behavioral design pattern that focuses on establishing a dynamic subscription-notification mechanism between objects. It defines a one-to-many dependency between objects, so that when … Read more
