基于S3C2440的nRF2401驱动设计

通信频率为2.4GHz的ISM频段,由于其免许可证、波长较短、天线的尺寸小、外围器件少等优点,适合于近距离无线通信。将ARM9与nRF24E1结合,可以缩小设备体积,降低系统功耗,减少设备间连线困难等问题。针对ARM9芯片S3C2440的特点设计了对nFR24E1的接口电路和驱动程序。对于在狭小空间中,有设备之间的数据共享要求的系统是一种有效解决途径。

nRF2401-driven Design Based on S3C2440

Communication frequency is 2.4GHz of the ISM band,because of their free permits,a shorter wavelength,the antenna size is small,less peripheral devices,etc.,suitable for short distance wireless communication.NRF24E1 combined with the ARM9,can reduce the equipment size,lower system power consumption,and reduced connectivity between devices difficult issues.In this paper,ARM9 chip S3C2440 features designed right nFR24E1 interface circuit and driver.For small spaces,there is sharing of data between devices require the system is an effective solution.
