不使用实时系统的话,用哪个方法可以实现SPI串口数据收发同步?

不使用实时系统的话,用哪个方法可以实现数据收发同步?

环境:win7,SDK:simplelink_cc2640r2_sdk_3_20_00_21,例程:rfPacketRx_CC2640R2_LAUNCHXL_nortos_ccs

  • 建议参考rfSynchronizedPacketRx及rfSynchronizedPacketTx:
    In this example you will learn how to build a time-synchronized connection between one transmitter and a receiver. Time-synchronization enables both communication partners to transfer data quickly at predictable time points. Unlike the wake-on-radio example, the transmitter does not need to send a very long preamble and the receiver does not need to wait and check for a signal on air. This leads to the lowest possible power consumption on both sides. It also fits very well to the SimpleLink Long-range mode. Time synchronization builds also the foundation for Frequency and Time Division Multiple Access, FDMA and TDMA respectively.
  • 不好意思,是我没说清楚。我说的数据收发同步是指做串口数据的收发同步,不是无线数据包收发同步
  • 没有提供串口同步的例程,可以参考下SDK里的UTC例程
