Essential for learning microcontrollers

Single-chip microcomputers are widely used in many products, whether it is the 51  series, AVR, or PIC  series, they all have their own characteristics, and the number of learners is increasing year by year. However, in the process of learning and development, we often spend a lot of money on experiments after determining the plan, especially for some students or beginners, this may become an obstacle to their learning. Since we used Proteus  software, we have greatly saved time and development costs. In particular, it is a good choice to use this software in single-chip microcomputer development  . Here we mainly talk about the combination and application of  Proteus  software and  Keil  software. Protues software introduction  Proteus  is currently the best tool for simulating single-chip microcomputer peripheral devices. It can simulate  51  series, AVR, PIC  and other commonly used  MCUs  and their peripheral circuits (such as LCD, RAM, ROM, keyboard, motor, LED, AD/DA, some SPI  devices, some  IIC  devices...). Of course, the software simulation accuracy is limited, and it is impossible to find the corresponding simulation model for all devices. Using development boards and simulators is of course the best choice, but for single-chip microcomputer enthusiasts, or simple development should be a better choice.  Proteus  is different from other MCU simulation software in that it can not only simulate the working conditions of MCU CPU, but also the working conditions of MCU peripheral circuits or other circuits without MCU. Therefore, when simulating and debugging programs, the concern is no longer about the changes in the contents of MCU registers and memories when certain statements are executed, but directly looking at the process and results of program operation and circuit operation from an engineering perspective. For such simulation experiments, in a sense, it makes up for the contradiction and phenomenon of disconnection between experiments and engineering applications.
