mmWaveLink的参考文档

根据功能将mmWaveLink划分为不同的Module：Device，Sensor，Data Path ，Monitoring ，Communication Protocol 。

SensorModule主要是控制毫米波前端中不同的HW block，HW block包含Chirp sequencer (Radar Timing Engine) ，Rx/Tx Channel，Rx Analog Chain，ADC and Digital Front End Configuration。

配置API可以大致分为以下几类：

mmwave static configuration, such as: Tx and Rx channel, ADC configuration etc
mmwave dynamic configuration, such as FMCW Chirp configuration, profile configuration
mmwave advance configuration such as Binary phase modulation, Dynamic power save etc
mmwave sensor control, such as: Frame start/stop
