01 What is a Real-Time Operating System (RTOS)? A Real-Time Operating System (RTOS) is an operating system designed to serve real-time applications. Such operating systems can quickly respond to and process data, with processing time requirements measured in increments of 0.1 seconds. The results must be able to control production processes or respond quickly to … Read more

1. Introduction to Queues A queue is a mechanism for data exchange between tasks, tasks and interrupts, and interrupts and tasks. Based on queues, FreeRTOS implements various functionalities such as queue sets and semaphores. All communication and synchronization mechanisms in FreeRTOS are based on queues. Queues have the following characteristics: 1.1. Data Storage Queues can … Read more
