How to Set the RTOS Tick Rate Appropriately?
Recently, a reader asked the following question: Why is the default configuration for the RTOS system tick (Tick) set to 1000? Can I configure it to 100, 10000, or 2000? Many beginners have this question, including myself when I first learned about RTOS. I was confused about what the different tick configurations meant and their … Read more
The Joy of Programmers: RTOS is Not as ‘Hardcore’ as You Think!

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
