The design of single chip computer system includes hardware design and software design of two parts. The traditional method is to first hardware design, then the software debugging. When the hardware circuit can not meet the design requirements, we need to change hardware circuit debugging. Proteus is a MCU system simulation software, the hardware circuit can not meet the design requirements, to directly modify the circuit simulation, until the system hardware and software are satisfied. In this paper PROTEUS software and compiling the software KEIL to do a simple introduction. This paper focuses on the single chip computer hardware environment of various parts of the circuit are introduced in detail, including keyboard, d
