毕业设计(论文)-基于AVR的遥控小车的设计-(4)

ABSTRACT

With the development of computer industry in recent years, LSI has gradually penetrated into all areas of society, while the single chip microcomputer because of its small volume, low power consumption, low price, low price, reliable work, and is the core of embedded system, has been widely used in our life, like electronic technology, communication, automobile, industry and other fields .

This design uses two AVR microcontroller (ATmega16) as the processor,which is run by the AVR chip to control the entire car.Two AVR microcontroller ATmega16 and nRF24L01 wireless module were used in this design in order to form a master-slave control system. Dual use wireless serial communication. The part of remote control use the FSK wireless the module rfm12b (433mhz) which produce by Hangzhou Mao Wei Science Co., Ltd. Because it can let the data have higher reliability. The trolley and remote control type communication protocol for data transmission, in accordance with the protocol established between them, thereby improving the effectiveness of the control. The control part is AVR microcontroller ATmega16 which have high-performance, low-power. Drive the car part of the of L298N single monolithic, four-channel driver designed to receive DTL or TTL logic levels and drive inductive load and switching power transistors.

The design is based on a complete hardware and software systems. So some function achieve perfectly, such as car remote control and any curve of travel.
