CCS/IWR1443BOOST: Issue with demo code

Part Number: IWR1443BOOST

Tool/software: Code Composer Studio

Hi,

I am trying to understand the 4k-FFT-lab example in the CS Resource. In the code description they have talked about some .png image files.

=====================================================================================================================

 @subsection antConfig Antenna Configurations
 *   @image html antenna_layout_2D.png "Antenna Configuration 2D (azimuth estimation)"
 *   \n
 *   @image html antenna_layout_3D.png "Antenna Configuration 3D (azimuth and elevation estimation)"
 *   \n
 *   As seen in pictures above, the millimeter wave demo supports two antenna configurations:
 *     - Two transmit antennas and four receive antennas. Transmit antennas Tx1 and Tx3
 *       are horizontally spaced at d = 2 Lambda, with their transmissions interleaved in
 *       a frame. This configuration allows for azimuth estimation.
 *     - Three  transmit and four receive antennas . The third Tx antenna, Tx2, is
 *       positioned between the other two Tx antennas at half lambda elevation. This
 *       configuration allows for both azimuth and elevation estimation.
 *
 *   @subsection data1d Data Path - 1st Dimension FFT Processing
 *   @image html datapath_1d_elevation.png "Data Path 1D"
 *   \n
 *   @image html datapath_1d_timing.png "Data Path 1D timing diagram"

Can i know where i can find these files?

regards,

Neha

    Hi,

    The 4K FFT lab was based on mmw demo of mmwave SDK. There are codes/comments that is no longer valid but didn't get cleaned up. The quoted part is an obsolete comments that should be taken out. 4K FFT is only an example to show for 1D FFT and no valid 2D FFT result. The display is using mmw demo visualizer. Only 1TX/1RX is supported due to limited hardware accelerator local memory size.

    Regards,
