CCS/IWR6843: HVAC project (How in the program Modify antGeometry0 /1 parameter value )

Tool/software: Code Composer Studio

Dear sir:

We design our own antenna (ISK), the antenna position is on the other side of the IC, The geometry and phase rotation of the antenna must be modified from the board. In the "68xx_Sense_and_Direct_HVAC_Control" HVAC project, the parameter settings of antGeometry0/1 have not been published. How do I make changes in the program, my antGeometry needs to be modified as follows

antGeometry0 -7 -6 -5 -4 -5 -4 -3 -2 -3 -2 -1 0

antGeometry1 -1 -1 -1 -1 0 0 0 0 -1 -1 -1 -1

PS:

Our Antenna geometry

		7	6	5	4
11	10	9	8	3	2	1	0

HI, Lin:

It looks right to me.

Best,

Hi Zigang:

At present, the "68xx_Sense_and_Direct_HVAC_Control" project does not support the parameter modification/setting function of antGeometry 0/1. If I want to modify the parameter value of antGeometry, how do I modify the program content from the MSS or DSS program, thank you.

What is the "68xx_Sense_and_Direct_HVAC_Control" project? Is it in the industrial toolbox (TiREX)?

If the antenna parameter is not parameterized, it will not be that easy to change. But in your case, you can try to interpolate the (x, y,z) as (-x, y, z).

Hi Zigang:

It is in the industrial toolbox (C:\ti\mmwave_industrial_toolbox_4_4_1\labs\people_counting\68xx_Sense_and_Direct_HVAC_Control)，

Directly interpolating (x, y, z) to (-x, y, z) I will have uneven strength on the left and right side of the antenna test, so I want to try to change antGeometry0 /1 parameter value in the program project), 
Confirm if it can be improved.

HI,

We can only support the features we have. This demo does not support flexible antenna pattern, you will have to walk through the code to find out the answer.

Best,

Zigang
