DCA1000EVM: simultanouseloy extracting processed data from the AWR1843boost and raw data from the DCA100EVM with ROS

Hi,

Can I just develop a driver that receives the UDP packets or is it much more complicated? 

Another question was if there's a way to access simultaneously the processed data from AWR1843Boost and the raw data from the DCA100EVM?  

Best regards,

Amine

Hi Raghu,

From the docs of the 'mmw' demo  'C:\ti\mmwave_sdk_03_02_00_04\packages\ti\demo\xwr18xx\mmw\docs\doxygen\html\index.html', it's mentioned that the lvds implementation is mostly present in mmw_lvds_stream.* . and from the source code in mss_main.c, the lvds stream is already initialized through 'MmwDemo_LVDSStreamInit'.  But it's not mentioned what are the further steps necessary to stream data over lvds.

should I add other functions like ' MmwDemo_LVDSStreamHwConfig' to configure the streaming of HW data over LVDS or does it work?

Thanks,

Amine 

Hi,

I tried to establish a connection with the DCA100EVM and receive the UDP packet sent like shown in the code below but there was no packet sent from the board even though the 'data_tran_prg' is blinking.

so I wanted to ask if there's some message exchange protocol between the DCA1000 board and the mmwave studio. If so, can you share some information about how the data is exchanged between the mmwave studio and the dca1000?

I would appreciate any help you can provide!

Best regards,
Amine
