IWR1443BOOST: TIDEP-0091:level sensing demo: timing measurement
Part Number: IWR1443BOOST
I recently got the TIDEP-0091 demo running on the MSP432 and the IWR1443. I can power on and off the IWR1443 just fine. However, whenever I try to take a single or continuous measurement, no data is being shown about the distances in the terminal window. It gets stuck after I enter a measurement command and does not allow me to enter another command. See picture below.
I added 0 ohm resistor R102 and R164, like the instructions mentioned to do. So I'm not sure what the problem is.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Akash Gondalia:
Also, this is the output I get when I uncomment the "#define REPORT_IR14_TIME_MEASUREMENTS" line and try to take a measurement.
In reply to Kyle Henderson:
Yes I can. I was looking into the issue and found a few things, and I have a few questions.
1) I never added R164, so I tried adding it. But it is very tough since the resistor is so small. In the getting started guide, it mentions that R164 is optional. So do I need R164 if I don't care about the timing measurements? I am only looking for distance outputs.
2) I have the "#define REPORT_IR14_TIME_MEASUREMENTS" line commented out in the MSP432 code. Is there anywhere else I need to comment it out? The other lines that I found that contain "REPORT_IR14_TIME_MEASUREMENTS" are #ifdef statements, so I wouldn't think those need to be commented out, but I'm not sure.
3) In the guide, it states to add 0 ohm resistor R162. I added this one, and I am able to turn the IWR1443 on and off. However, in the picture on the guide, R9 is also pointed to, but never mentioned. Do I need to add a 0 ohm resistor to R9 as well?
4) When I mated the MSP432 and IWR1443, then removed the MSP432, it pulled off a trace on the IWR1443 on J4. I have included a picture. Will this be a problem with getting the distance outputs? I saw on the schematic that the trace connects to SOP0, so i'm hoping it won't affect the functioning of the level sense demo.
