IWR6843AOPEVM: 根据user's guide跑vitalSign demo无波形输出

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: MMWAVEICBOOST

利用IWR6843AOPEVM板跑vitalSigndemo遇到的问题现象:

1. 根据user‘s guide 跑vitalSIgn demo,mmwave_industrial_toolbox_4_7_0\labs\vital_signs\68xx_vital_signs\gui\gui_exe\VitalSignsRadar_Demo.exe第一次有波形输出,后面重刷之后就再也没有波形输出

2. 手动向串口发送命令"calibDcRangeSig -1 0 0 0 0",发生错误Error: Number of averaged chirps is not power of two. Error: -1. 而此时的cfg参数来自官方的1642的cfg文件

求助:如何把vitalSign demo正确的跑起来?
