The Six Important Parts of Microcontroller Learning Applications 1. Bus: We know that a circuit is always formed by connecting components through wires. In analog circuits, wiring is not a problem because the relationship between components is generally serial, and there are not many connections between components. However, computer circuits are different; they are centered around … Read more
For engineers working with microcontrollers, especially those using the 8051 series, the question often arises when discussing RTOS: “Why use RTOS? With such limited resources in microcontrollers, can RTOS ensure efficiency?” In response to this question, I would counter: “What is your purpose in using a microcontroller? Is it to program in C, assembly, or … Read more
