3.2 Software, Development Tools, and Example Codes for MMWCAS-RF-EVM

The Cascade Radar kit belongs to a larger TI ecosystem of hardware and software tools.

To enable immediate evaluation of the Cascade Radar kit TI provides the mmWave Studio RF evaluation GUI and Lua scripting environment. This mmWave Studio tool interfaces to the MMWCAS-RF-EVM through the MMWCAS-DSP-EVM host board and masters the TDA2Sx host processor, enabling configuration, control and data capture of the AWRx devices on the MMWCAS-RF-EVM. mmWave Studio includes example single-device, multi-device MIMO and multi-device TX-beamforming configurations. Example capture Lua scripts are also included.

A Matlab code base for MIMO and TX-Beamforming post-processing and calibration has also been developed and included in mmWave Studio. This post-processing code is designed to work on the raw captured ADC samples and includes examples of basic 1D, 2D and 3D-FFT processing for creating range-doppler and point-cloud datasets from the MIMO and TX-Beamforming data.

To enable development of an end application with single-device and cascaded AWRx, TI provides the device firmware packages (DFP).

The DFP includes the MSS and BSS firmware, or firmware patches, as well as the mmWave Link Framework and framework implementation examples. The mmWave Link Framework provides a C-source implementation of the AWRx Interface Control Document (ICD) defined API.
