Embedded tools and accessories are a variety of hardware and software that are used in the development of embedded systems. They range from compilers, debuggers, and real-time operating systems to sensors and testing devices. Embedded tools and accessories are used to create, debug, and deploy embedded systems. Compilers are used to transform source code into the low-level machine code that is executable by the system. Debuggers are used to find and fix errors in the code. Real-time operating systems are used to control the timing and execution of tasks on an embedded system. Sensors and testing devices measure the performance and behavior of an embedded system, while other tools help to configure, monitor, and control the system.
