Embedded Systems Currently, common embedded consumer products are either applications of bare-metal embedded systems based on microcontrollers or applications of embedded Linux systems. Among these, the former represents relatively low-end products with simple functions, while the latter is of higher grade, featuring complex functionalities and interactive systems that are more convenient for user operation. An … Read more
Hello everyone, I am the Intelligence Guy~ During the development of RTOS, you must have encountered the issue of priority inversion, where a low-priority task is preempted by a higher-priority task due to shared resource access. This contradicts the real-time performance of a preemptive kernel. The core of solving the priority inversion problem in RTOS … Read more
