Abstract
The stopwatch is widely used in daily life, especially in sports, so the accurate and convenient stopwatch is chosen by more and more people. The digital electronic stopwatch has the advantages of intuitive display, easy reading and high precision, and is widely used in timekeeping. This design is a multifunctional stopwatch system controlled by single chip microcomputer it is based on 51 series of single chip microcomputer system design, using its timer/counter timing and counting principle, combined with display circuit, power circuit, LED digital tube and keyboard circuit to design timer. The software and hardware are organically combined, using a 6-digit digital tube as the display module of the design, using three keys to control it, can achieve a key record multiple values. The software system uses C language to write programs, including display program, counting program, interrupt program, delay program, etc. The hardware system uses the powerful functions of PROTEUS to achieve, simple and easy to observe, you can observe the actual working state in the simulation. Its outstanding advantages: small size, the lowest power consumption, suitable for battery as a power supply, compact hardware structure, simple and flexible software design.
