CCS/AWR1443: Custom AWR 1443 Firmware? Generate own radarss.bin

Part Number: AWR1443

Tool/software: Code Composer Studio

Hello,

I'm wondering whether I can change the AWR 1443 firmware, specifically, I want to change the MmwDemo_output_message_type_e in mmw_output.h in io_interface. Seems this belongs to BSS image?

Thanks,

    Hi,
    You can change these ENUM to add a new type of message type.
    It's not part of BSS, you can change/append and built the application as you need.

    Hi Jitendra,

    Thanks for your reply. I tried to change the ENUM to output the full radar cube. But seems the size is too large to transmit through UART. I'm wondering what else can be done? I'm mainly interested in calculate the 3D heat map. (the 2D azimuth heat map provided in demo but with 3 TX and to calculate the elevation. Only needed for static.)

    Thanks,
    Shiwei

    Hi Shiwei,

    You can refer to 'MmwDemo_transmitProcessedOutput' function where you can send your required data over UART.

    As for rangeDopplerheatMap--  UART_writePolling (uartHandle,  (uint8_t*)obj->rangeDopplerLogMagMatrix, tl[tlvIdx].length);

    To obtain 3D heat map, you need to go through post_processing.c file where it calculates azimuth and elevation of given object and combine these data. And use profile_3d.cfg configuration file.

    Regards,
