Introduction

This example performs HWA based FFT1D operation on the ADC real chirp samples.

The input to the FFT is the ADC data from the ADC buffer, mapped to the HWA internal memory in the FFT1D trigger mode. This eliminates the need for additional EDMA copy of ADC data into HWA and subsequent trigger. The HWA PaRAM sets are initialized with proper configuration. The HWA is triggered to perform the FFT operation, upon availability of ADC chirp samples and the frequency domain complex output is converted back to 16-bit signed data. Moreover, this example is configured to chirp for 1 frame containing a single burst of chirp signals, having 128 samples per chirp.

Using SDK with SysConfig

A GUI tool SysConfig is used to configure different modules and peripherals of the example. Using this tool, users can select and customize different modules and peripherals. The SysConfig tool will generate the code for initializing and configuring these modules. This configuration is saved to a file called example.syscfg for every example.

Using SDK with SysConfig

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
