AWR1843: rlRfSetPhaseShiftConfig 对chirp 配置理解

Part Number: AWR1843

专家:

我们利用mmwave_automotive_toolbox_3_5_0 lab中运行lab0007_medium_range_radar,在中断处理函数MRR_MSS_chirpIntCallback()增加类似与lab011的相位配置函数,在每一个chirp中断到来后改变下一个chirp的相位,程序已经运行成功,问题是DDMA的波峰数目不对

1.这样设计能够做到每个chirp相位改改变吗》对chirp的idletime 有要求吗?

2rlRfSetPhaseShiftConfig 这个函数处理的是 相位/5.625吗?比如tx0 移相位22.5°,码字是22.5/5.625=4,txtx0PhaseShift =4,手册上是个描述。
