IWR6843AOPEVM: Outputting vital sign data to LCD display using ICBOOST carrier board
Howdy,
I am trying to access the vital signs variables located in the mss_main.c TLV packet pictured below. I am having trouble accessing the vital sign variables and was hoping I could I could receive some guidance on how to access the packet ( I am currently using a pointer what I believe is the packet uint8_t* data = (uint8_t**)&message.body.detObj.tlv[itemIdx];). I am trying to display the values on an external screen so is there a way to access the values directly, or a parser that is known to function inside code composer.
Thank you in advance,
Ally
Hello Ally,
As you can see there, the output values are being written out over UART in the TLV data format. See these guides: Understanding UART Output and Vital Signs UART Output.
To display the values in your own way, you must catch and parse these packets over UART. This is exactly what our various visualizers do, so you can look at the source of those, e.g. <RADAR_TOOLBOX_DIR>/tools/visualizers/Industrial_Visualizer/parseTLVs.py . Look through this script, and specifically at the vital signs TLV section:
Regards,
Luke
