为了提高智能赛车的性能,需要得到赛车运行中的相关参数。本文以nRF2401 无线 数传芯片为核心,以HCS12DG128 控制发射,以AT89C2051 控制接收,采用MAX232 将 数据发送给计算机,在计算机中对数据进行分析得到赛车的运行参数,以此来提高赛车的运行速度。 关键词:nRF2401;AT89C2051;串行通讯;VC.NET Abstract: In order to improve the smart car’s performance, it’s necessary to get parameters of smart while running.Based on the nRF2401 wireless transfers chip, using HCS12DG128 to control emission, using AT89C2051 to control receive and adopt MAX232 to transmit data to computer. By analysis this data of smart car ,it can improve the speed of smart car. Keywords: nRF2401;AT89C2051;Serial Communication;VC.NET
