IWR1642BOOST: IWR1642 interfacing the device using MATLAB GUI

Hi,

1. I am working on people count project using IWR1642. I was able to run the demo image and visualize the output using Matlab GUI. But when I execute the same on the Matlab code, it throws an error message "error while evaluating uicontrol call back".

This may have to do with the MATLAB version you're running. Take a look at the error message to see if perhaps an outdated function is being called.

2. I would like to read the output data using a serial monitor from IWR 1642. How can I do this?

You can read the output in Tera Term. See the MATLAB code for the port settings.

3. How can I interface Lauchpad with IWR 1642 and read the output data? Is there any demo?

The demo outputs over UART, so you can interface with any number of devices. You will have to write the code for the separate device though.

Hi,

What toolbox version is the customer using? We may not know the MATLAB version, but if they look at the actual error that MATLAB is throwing, they may be able to modify for their version.

Additionally, take a look at this related post. Do you have the webcam package?

HI Vivian,

I would like to visualise the data in the fHist file in the serial monitor. How can I take the data to the serial monitor?

I would recommend the customer write a parsing script that prints the relevant data to the serial monitor then. We have a number of examples in the visualizers folder that show how they can extract the relevant information. The Industrial Visualizer in the newest toolbox release shows an example of this in python. While it is not meant for the 3.5 toolbox on the 1642 device, it could be modified to accommodate it.

Hi,

We do not review large pieces of code on the forum. If the customer has the fHist file in MATLAB, they should have everything they need to visualize the data. We are happy to answer more directed questions if they arise.
