Please check the function in your code that converts start frequency to the equivalent constant value for the device. You can use the following SDK function as a reference for converting the application parameters to the device constants. You can also use the mmWaveSensing Estimator to get these values for quick testing.
File: C:\ti\mmwave_sdk_03_01_01_02\packages\ti\utils\cli\src\cli_mmwave.c
Function: CLI_MMWaveProfileCfg()
给出了解决办法,把代码中的start frequency改成77GHz。

但是我的6843是60g的啊,我找到了原因
#define CONV_FREQ_GHZ_TO_CODEWORD(X) (uint32_t) ((float)X * (1e9) / 53.644)//77G device#define CONV_SLOPE_MHZ_PER_US_TO_CODEWORD(X) (ROUND_TO_INT32(X * (1000.0/48.279)))
这两个都是在77g的定义,我只找到了#define CONV_FREQ_GHZ_TO_CODEWORD(X) (uint32_t) ((float)X * (1e9) / 40.233)//60G device,还有一个我应该怎么改

请问使用的是哪个demo? 在代码里搜不到吗?

你好,
你的代码看起来是自己的代码,我没有在out of box demo里找到signalDesign.h。
对于你的问题,请参考下面blog信息。
