Abstract：This paper introduces a wireless data transmission system which is composed of a kind of wireless data transmission chip and MCU. The system, whose core is the wireless transmission chip nRF24L01, employs the MC9S12DG128B to control the data transmission using USB24L01 as the wireless receive module and sending the data to the host computer through the USB interface. And the data is analyzed and optimized by the computer to get the related parameters and motion trajectory of the model car, through which to improve its speed and handling stability. This system is characterized by its simplicity, high reliability, high transmission rate, small volume, low cost and low power dissipation.
