Other Parts Discussed in Thread: AWR1443,
雷达相关的硬件配置参考我原先的帖子：
为了完成Hardware Trigger，我卸除了DCA1000上的R120电阻，通过J5 P10将SYNC_IN接入STM32的定时器上，通过STM32定时器输出2us的3.3V短脉冲以触发。
以下为我精确地生成了20个2us短脉冲示波器图（紫色）：
但最终实际录制到的adc_data_Raw_0.bin仅为12 kb：
另附以上文件的压缩包：
然而当我配置模式为Software Trigger模式时，它正确地录制了240KB的数据：
文件如下：
从上面观察来看，短脉冲确实能够触发雷达工作但是不知原因为何，DCA1000只录制了最开始的一帧便不再工作。
相关的lua脚本分为俩部分：配置和录制：
