IWR6843LEVM: How do I get ADC data in real time when I using IWR6843LEVM and DCA1000EVM instead of using the mmWave Studio tool to get only the stored bin file?

Hello,

If you are using mmWaveStudio (Guide: https://dev.ti.com/tirex/explore/node?a=1AslXXD__2.10.00.04&node=A__AGTrhNYW8jE6cMxbovlfaA__radar_toolbox__1AslXXD__2.10.00.04&placeholder=true) and loading the BSS and MSS FW, you will have to load it every time. If you use DCA1000 Data Capture tool which uses Out of Box demo as the base you only need to flash it once. We recommend people to use the DCA1000 Data Capture Tool (Guide: https://dev.ti.com/tirex/explore/node?a=1AslXXD__2.10.00.04&node=A__ACcj5qsn5G-kyhEttWYAjg__radar_toolbox__1AslXXD__2.10.00.04&placeholder=true) unless there is a niche need for something only mmWaveStudio supports.

Hi，Pedrhom

Thank you very much for your support!

I have tried to use the tool and collected the adc data using the default configuration of the radar, when I need to define multiple profileCfg

configurations, I find that there is no adc data output

xWR6843_presenceDetection.cfg

profileCfg 0 60.00 205 11 41 0 0 97.00 1 64 2200 0 0 36

chirpCfg 0 0 0 0 0 0 0 1
chirpCfg 1 1 0 0 0 0 0 2
chirpCfg 2 2 0 0 0 0 0 4
frameCfg 0 2 220 0 200 1 0

can get the adc data !!!

but when set:

profileCfg 0 60.00 205 11 41 0 0 97.00 1 64 2200 0 0 36

profileCfg 1 60.00 205 11 41 0 0 97.00 1 64 2200 0 0 36

chirpCfg 0 0 0 0 0 0 0 1
chirpCfg 1 1 0 0 0 0 0 2
chirpCfg 2 2 1 0 0 0 0 4

frameCfg 0 2 220 0 200 1 0

can not get adc data, why? can you help me? the fw verion I use for IWR6843 is radar_toolbox_2_10_00_04\tools\Adc_Data_Capture_Tool_DCA1000_CLI\prebuilt_binaries\xwr68xx_mmw_demo.bin

xwr68xx_mmw_demo.bin does not support multiple profileCfg configuration delivery?

and I want to ask another question, 

When I don't want to save the ADC data as a bin file, can I do without using DCA1000EVM_CLI_Control.exe and DCA1000EVM_CLI_Record.exe tools? I want to send configurations and commands directly through UDP (port: 4096) and get ADC data in real time via UDP (4098), is that okay? After testing, yes, but will there be any other problems?

command_dict = {
    'RESET_AR_DEV_CMD': bytearray.fromhex('5aa502000000aaee'),
    'CONFIG_FPGA_GEN_CMD': bytearray.fromhex('5aa50300060001020102031eaaee'),
    'CONFIG_PACKET_DATA_CMD': bytearray.fromhex('5aa50b000600be05350c0000aaee'),
    'SYSTEM_CONNECT_CMD': bytearray.fromhex('5aa509000000aaee'),
    'RECORD_START_CMD': bytearray.fromhex('5aa505000000aaee'),
    'RECORD_STOP_CMD': bytearray.fromhex('5aa506000000aaee')
}

the test code using python is as below,

DCA1000_IP = '192.168.33.180'
command_port = 4096
data_port = 4098

radar_config = 'config/xWR6843_presenceDetection.cfg'

command_dict = {
    'RESET_AR_DEV_CMD': bytearray.fromhex('5aa502000000aaee'),
    'CONFIG_FPGA_GEN_CMD': bytearray.fromhex('5aa50300060001020102031eaaee'),
    'CONFIG_PACKET_DATA_CMD': bytearray.fromhex('5aa50b000600be05350c0000aaee'),
    'SYSTEM_CONNECT_CMD': bytearray.fromhex('5aa509000000aaee'),
    'RECORD_START_CMD': bytearray.fromhex('5aa505000000aaee'),
    'RECORD_STOP_CMD': bytearray.fromhex('5aa506000000aaee')
}

def send_DCA_command():
    
    with socket.socket(socket.AF_INET, socket.SOCK_DGRAM) as sock:
        sock.bind(('', 4096))
        sock.settimeout(5)
        sock.sendto(command_dict['RESET_AR_DEV_CMD'], (DCA1000_IP, command_port))
        time.sleep(3)
        sock.sendto(command_dict['CONFIG_FPGA_GEN_CMD'], (DCA1000_IP, command_port))
        time.sleep(0.5)
        sock.sendto(command_dict['CONFIG_PACKET_DATA_CMD'], (DCA1000_IP, command_port))
        time.sleep(0.5)
        sock.sendto(command_dict['SYSTEM_CONNECT_CMD'], (DCA1000_IP, command_port))
        time.sleep(0.5)
        sock.sendto(command_dict['RECORD_START_CMD'], (DCA1000_IP, command_port))
        time.sleep(0.5)
        send_radar_config() # send radar config to IWR6843 with COM port

def stop_record():
    with socket.socket(socket.AF_INET, socket.SOCK_DGRAM) as sock:
        sock.bind(('', 4096))
        sock.settimeout(5)
        sock.sendto(command_dict['RECORD_STOP_CMD'], (DCA1000_IP, command_port))

get adc data:

# with socket.socket(socket.AF_INET, socket.SOCK_DGRAM) as sock:
#     sock.bind(('', data_port))
#     sock.settimeout(5)
#     while True:
#         response, server = sock.recvfrom(2048)  # 1024字节的缓冲区大小
#         print(f"Response received from {server}: {response.hex()}")

Hello, 

Sorry for the delay. Pedrhom is currently out of office. He will respond when he returns next week. Thank you for your patience. 

Best Regards,

Josh
