In the 21st century, technology has advanced rapidly. The microcontrollers in the hands of geeks have evolved from the old 51 and PIC to AVR and STM32, along with various convenient development tools, such as the once-popular Arduino. However, the Atmega328-based AVR microcontroller is still quite outdated, being almost 20 years old, while ARM is … Read more
In embedded development, multitasking is key to improving system efficiency and functionality. For resource-constrained microcontrollers, traditional preemptive multitasking frameworks (like FreeRTOS) can be overly complex and resource-intensive. In this case, the lightweight cooperative multitasking scheduler TaskScheduler becomes an ideal choice. Introduction to TaskScheduler TaskScheduler is a library that provides cooperative multitasking capabilities for microcontrollers such … Read more
