Hi,

I am using IWR6843ISK-ODS. The demo is "lab0023_multi_gesture_and_motion_det_68xx" in the "mmwave_industrial_toolbox_3_6_2". In the “dss_main.c” file, the code located between the 983^th and the 986^th:

message.body.detObj.header.magicWord[0] = 0x0102;

message.body.detObj.header.magicWord[1] = 0x0304;

message.body.detObj.header.magicWord[2] = 0x0506;

message.body.detObj.header.magicWord[3] = 0x0708

I didn’t get the code meaning. Especially what does the magicWord refer to?

Hi Victor

The magic word is sent to mark the beginning of the output data for each frame. The receiver, e.g. Visualizer on PC looks for this word in the data stream and once it finds it, it can start decoding the output structure.

Thanks
