A Design of Automatic Bus Station Reporter Based on the Interrupt System of ATmegai 28

摘要

On the basis of GPS module, MP3 module and GPRS module, we aim at designing a bus station reporter developed by the interrupt system of ATmegal28. This kind of reporter can make use of the rich interrupt sources provided by ATmegal28 to accomplish the functions like receiving and sending the longitude and latitude data, announcing voice messages etc and deal with the reporter's multifunction, which MCU cannot accomplish at the same time. In addition, the use of interrupt system can greatly simplify the programming, reducing its difficulty and at the same time, it is more convenient for the reporter to expand its functions.
