Tool/software:
Hi! TI TEAM!
I am using IWR6843ISK and trying to dump the RangeProfile.
But I am not familiar with this process so I find the document in radar_toolbox_2_30_00_12\software_docs\Understanding_UART_Data_Output_Format.html
Range Profile
xWR6843, xWR1843, xWR1642, xWR1443
| Type Identifier | Type Value | Length | Value |
|---|---|---|---|
| 2 | MMWDEMO_OUTPUT_MSG_RANGE_PROFILE |
(Range FFT size) x (2 Bytes) | Array of profile points at 0th Doppler (stationary objects). The points represent the sum of log2 magnitudes of received antennas expressed in Q9 format. |
So the document say that this is 2 Bytes.
But in the code
UART_writePolling (uartHandle,
(uint8_t*)&tl[tlvIdx],
sizeof(MmwDemo_output_message_tl));
for(index = 0; index < subFrameCfg->numRangeBins; index++)
{
UART_writePolling (uartHandle,
(uint8_t*)&detMatrix[index*subFrameCfg->numDopplerBins],
sizeof(uint16_t));
}
Supposed this is (uint8_t),
So which one is right? Please help me. Thank you!
The following is the partial message from the rangeProfile

from 0 to 30. You can see this is weird.
Please help me!
Best regard,
