IWR1642: How to use continuous chirping for testing?

Hi,

If its a demo you can look in the configuration file.
Below is the configuration file for the high accuracy lab

dfeDataOutputMode 1
channelCfg 1 1 0
adcCfg 2 1
adcbufCfg 0 1 1 1
profileCfg 0 77 7 7 114.4 0 0  33.71 1 512 5000 0 0 48
chirpCfg 0 0 0 0 0 0 0 1
frameCfg 0 0 10 0 500 1 0
lowPower 0 1
guiMonitor 1 1 0 0 0 1
RangeLimitCfg 2 1 1.0 3.0
sensorStart

Here you can see in red, that "frameCfg 0 0 10 0 500 1 0" , this controls the number of frames, if you set it to zero then it infinetly repeats.

For details click here, and download the "Users Guide", go to "3. 4. Configuration (.cfg) File Format", located on page 13.

If you are using mmWave studio with DCA1000 you can do the same:

hope this helps.

Hello,

Thanks, I'm trying.

More two questions:

1. What's 0~6m (check pic.)?

2. Is possible IWR1642 tx can generator pulse (wave) for testing? 

Hi,

1) The peak value corresponds to the FFT peak value of the detected object. This value does not have a unit and objects with a stronger reflection will produce a higher peak value. This is also discussed in the following threads:

LINK2

2) Pulse is not supported.
