[Other Embeded program] CC1100_CPLD DL : 0: 基于CC1100和CPLD的时差法测距实验以GPS秒脉冲为复位信号及开始计时的时间基准, 同时作为无线发射的触发信号。计时由CPLD计数时钟脉冲实现，当发射机发射完毕后CC1100模块给出中断，中止主机CPLD的计时，得到发射时间脉冲数n1；当接收机CC1100接收到数据包后，给出中断，提醒单片机处理，并且中止接收部分CPLD的计时，得到收到时间脉冲数n2。由n2-n1乘以时钟周期可得电波的传播时间。程序包括：CPLD计时器程序，单片机控制CC1100程序，简要的说明文档（有实物照片） 2009/10/10整理沨-CC1100 and CPLD based on the time difference between France Ranging experiment to GPS PPS signal for the reset and start timing the time base at the same time as a wireless trigger signal emitted. Time counting clock pulses from the CPLD, when the transmitter launch CC1100 module is given after the interruption, suspension of the host CPLD timing, to be launch pulses n1 When the CC1100 receiver receives the data package, given interrupted to remind the single machine processing, and the suspension of receiving part of the CPLD of the timing, get the time of receipt pulses n2. N2-n1 multiplied by the clock cycles available to the travel time of radio waves. Procedures include: CPLD timer program, CC1100 MCU control program, a brief description of the document (with things in photo), 2009/10/10 finishing Feng
