IWR6843ISK: How to Config for Range up to 14 meter on People Counting Lab

Hello Kevin,

Can you please give more information what you are looking at to say the Y value is always less than 7? I just verified that the recorded value is >7 when I walked to about 8m from the sensor using the 14m default cfg.

How are you running the sensor and verifying the output?

Regards,

Jackson

Hi Jackson,

(1) Please checking the following picture,

     for example: at the row 3 on the POS=(x, y, z) shown y value '+06.485'

(2) More information what cfg file be used,

(3) I had done some tests that the Y value can be found up to 7 m but LESS then 8 m when I walked to 14 m

Hi Jackson,

I had done some tests that the Y value can be found up to 7 m but LESS then 8 m when I walked to 14 m

Please check at row 7 show y value '+07.715'

Hi Jackson,

(1) I comment out the original MagicWordHeader, TargetList and TargetIndex etc codes

    and write a short codes instead on MmwDemo_uartTxTask() in mss_main.c

    as followings,

//*************************************************************************************************************

//* show TID, POS, VEL, ACC results in READABLE format

//* via UART DATA port with baud rate 921600 by Tera Term

            static uint32_t JBL_U32 = 0L;
            static uint32_t JBL_targetNumberU32 = 0L;
            static uint32_t JBL_U8 = 0;

            //* FLOW
            JBL_U8 = (JBL_U32++ % 10) + '0'; // show '0'..'9'

            UART_write(uartHandle, "JB> flow=", sizeof("JB> flow="));
            UART_write(uartHandle, &JBL_U8, 1);

            #if(1) // show TID, POS, VEL, ACC; ALERT: just show only ONE target here
            //* TARGET NUMBER, 112 := length of structure TARGET LIST
            JBL_targetNumberU32 = (targetListLength - sizeof(Pcount3DDemo_output_message_tl)) / 112;
            UART_write(uartHandle, ", TAR=(", sizeof(", TAR=("));
            jb_UART_writeU32(uartHandle, JBL_targetNumberU32);
            //* TID
            UART_write(uartHandle, "), TID=(", sizeof("), TID=("));
            jb_UART_writeU32(uartHandle, (gMmwMssMCB.trackerOutput.tList[gMmwMssMCB.trackerOutput.currentDescr]->tid));
            //* POS
            UART_write(uartHandle, "), POS=(", sizeof("), POS=("));
            jb_UART_write(uartHandle, gMmwMssMCB.trackerOutput.tList[gMmwMssMCB.trackerOutput.currentDescr]->posX);
            UART_write(uartHandle, ",", 1);
            jb_UART_write(uartHandle, gMmwMssMCB.trackerOutput.tList[gMmwMssMCB.trackerOutput.currentDescr]->posY);
            UART_write(uartHandle, ",", 1);
            jb_UART_write(uartHandle, gMmwMssMCB.trackerOutput.tList[gMmwMssMCB.trackerOutput.currentDescr]->posZ);
            //* VEL
            UART_write(uartHandle, "), VEL=(", sizeof("), VEL=("));
            jb_UART_write(uartHandle, gMmwMssMCB.trackerOutput.tList[gMmwMssMCB.trackerOutput.currentDescr]->velX);
            UART_write(uartHandle, ",", 1);
            jb_UART_write(uartHandle, gMmwMssMCB.trackerOutput.tList[gMmwMssMCB.trackerOutput.currentDescr]->velY);
            UART_write(uartHandle, ",", 1);
            jb_UART_write(uartHandle, gMmwMssMCB.trackerOutput.tList[gMmwMssMCB.trackerOutput.currentDescr]->velZ);
            //* ACC
            UART_write(uartHandle, "), ACC=(", sizeof("), ACC=("));
            jb_UART_write(uartHandle, gMmwMssMCB.trackerOutput.tList[gMmwMssMCB.trackerOutput.currentDescr]->accX);
            UART_write(uartHandle, ",", 1);

(2) The sensor is mounted 2m high and 15 degree tilt

(3) The parameters of configuartion on boundary,

staticBoundaryBox -3 3 2 10 0 3
boundaryBox -4 4 0.5 12 0 3
sensorPosition 2 0 15
gatingParam 3 2 2 2 4

(4) I will try again on change back the original frame rate setting as 55 ms

    Any suggest?
