"FreeRTOS Source Code Detailed Explanation and Application Development: Based on STM32" is supplemented by a large number of routines to comprehensively explain the principles and source code of FreeRTOS. The main content includes task management and task scheduling, system reduction and configuration, time management, queues, semaphores, software Timers, event flag groups, task notifications, low-power Tickless mode, idle tasks and memory management, etc. At the same time, "FreeRTOS Source Code Detailed Explanation and Application Development: Based on STM32" is equipped with a large number of illustrations, which is a good choice for those who want to learn the principles of RTOS systems in depth.
Preface: Fire monitoring and alarm system can convert physical quantities such as smoke, heat, and flames generated by combustion into electrical signals through fire detectors at the early stage of f
Testing a battery-powered product, there is a 26K resistor between the two ends of the battery pad (no battery is soldered at this time!), what is the internal resistance of the board power supply cir
The MOSFET driver circuit chip IR2110 has an output current of about 2A. Is this the drive current? The output voltage is 10-20V. So the output power of the tube is IU, or how to calculate it? Then th
