Compiler/TDA2PXEVM: Support for null source input/output with radar FFT?

RTOS/TDA2PXEVM: Specifying radar data configuration for null source input + radar FFT + null output?

Hi, 

The configuration file for the sample input data of the radar demo specifies 4 receivers and 1 transmitter. Is it possible to configure the demo for radar data generated by a different configuration, such as 8 receivers and 1 transmitter? 

Thanks,

Richard

    Richard,

    Do you have the data for 8 transmitters ready with you? you can change the macros in the vision_sdk\apps\src\rtos\radar\src\usecases\radar_read_fft_write\chains_radarreadfftwrite.c to achieve the different configuration.

    #define CHAINS_RADAR_INPUT_FILE "Input_512x128_4Rx_1Tx_1TS_10Frm.bin"
    #define CHAINS_RADAR_CHIRP_SIZE (512U)
    #define CHAINS_RADAR_HEIGHT (128U)
    #define CHAINS_RADAR_NUM_RX_ANTENNA (4U)
    #define CHAINS_RADAR_NUM_TX_ANTENNA (1U)
    #define CHAINS_RADAR_NUM_FRAMES (10U)
    #define CHAINS_RADAR_HEAT_MAP_RANGE_RES ((float)0.07862822061191625)
    #define CHAINS_RADAR_HEAT_MAP_VELOCITY_RES ((float)0.2256548202963532)

    Thanks and regards,
