DCA1000EVM: DCA1000evm and iwr1443

Hi, 

If you plan to use two chirps, you need to program both chirps

ar1.ChirpConfig(0,0,0,0,0,0,0, 1, 0, 0)

ar1.ChirpConfig(1,1,0,0,0,0,0, 0, 0, 1)

Now, you have both chirp 0 and chirp 1 configured, you can then send frameConfig.

Thank you very much for your help. I set it up according to your suggestion. No error was reported.

But I'm not sure if my procedure is correct. Could you check it for me?I will be deeply grateful.

My steps are as follows:

1. Set up the sensor configuration box and click Set

2. Check Tx0 in the chirp box, enter ar1. ChirpConfig (0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0) in the Lua shell and execute.

3. Set the frame parameter and click Set

4. Check Tx2 in the chirp box, enter ar1. ChirpConfig (1, 1, 0, 0, 0, 0, 0, 0, 1) into the Lua shell and execute it.

5. Set the frame parameter and click Set

The output box is shown below.

HI,

Please skip your step (3)

Step (2) program chirp 0, step (4) program chirp 1.   You can either enter through GUI or send the comment.  Either way is fine.

After all the chirps are programmed, then you can program the frame configuration , which is your step (5).

By the way, here is a step by step documentation on DCA1000 data capture.

Dear zigang Yang，your answer is easy to understand and has solved my problem very well. Now the data I have measured have achieved good results.

Thank you very much for your help！
