Microsecond-Level Delay Design Solutions Generally, in an RTOS system with a clock of 1KHz, the minimum time for thread_sleep() is 1ms. In real-time control, there are situations where microsecond (us) level delays are required. What should we do in this case? There are two implementation approaches for microsecond-level delays: one is to increase the system … Read more
I have been planning to record GUI video tutorials, but I couldn’t figure out how to do it. After some time of consideration and suggestions from netizens, I decided to make it a comprehensive practical video, where each function is an independent application. Tencent Video: Bilibili Video: Video Outline: Reference Materials: The 3rd edition of … Read more

Dynamic APP loading techniques for microcontrollers are similar to applications on mobile phones and computers, allowing programs to be loaded from various sources such as SD cards, NAND, NOR, eMMC, etc., into execution spaces like SRAM, SDRAM, QSPI Flash, and internal Flash. Moreover, if MPU support is available, it can isolate APPs; if an APP … Read more
Explanation:1. In general applications, we usually set the task RTOS system clock tick (heartbeat) to 1ms, but if we directly set the RTOS system clock tick to 1us, the system burden is very high, and many RTOS cannot switch tasks every 1us at a 100MHz main frequency, resulting in the RTOS not having time to … Read more
