我现在需要使用AWR2243级联板实现DDMA模式的数据采集，步骤如下：
1、根据MIMO的配置文件修改出了DDMA的基本参数配置文件，主要是修改了Configure_Chirps函数里面的ChirpConfig_mult，使得每个雷达芯片的三个发射天线同时使能。
代码如下

A. CONFIGURATION
1. Connecting to TDA
1. Configuring Master from SOP till Channel Config
2. Configuring Slave (i) sequentially from SOP till SPI Connect. i = 1, 2, 3
3. Configuring Slaves together from F/W download till Channel Config
4. Configuring all devices together from LDO Bypass till Frame Config
NOTE:
Update the following in the script accordingly before running
1. metaImage F/W path on line 32

2、配置各个发射天线的相移
首先根据以下matlab代码计算出相移值
%参数设置
PhaseMin = 5.625;
numTx = 12;
numChirps = 256;
numEmptybands = 0;
EmptybandIndex = 1;
%为1表示处在Tx1与Tx2之间，为2表示处在Tx2与Tx3之间，以此类推。 (不过无论几个emptyband，这里默认它们是连续的)
%不过不管emptyband是如何放置的，后续具体使用时找到Tx对应的行即可。
%相位值计算
N_all = numTx + numEmptybands;
PhaseSetp = 360/N_all;
Idea_Phase = zeros(N_all,numChirps); %预设一个矩阵装载相位。
Real_Phase = zeros(N_all,numChirps); %实际的相位
IndexUse = zeros(N_all,numChirps); %实际相位对应的应该设置的index值： 从0--63
for ii = 1:N_all
PhaseSetp_use = (ii-1)*PhaseSetp;
for jj = 1:numChirps
Phasetmp = rem( (0 + (jj-1)*PhaseSetp_use),360);
Idea_Phase(ii,jj) = Phasetmp;
Quatient = round(Phasetmp/PhaseMin);
Real_Phase(ii,jj) = Quatient*PhaseMin;
IndexUse(ii,jj) = Quatient;
end
end
相移结果如下：
IndexUse =

4、捕获
根据以下lua代码进行捕获
--[[
A. FRAMING & CAPTURE
1. Triggering Slave (3, 2, 1) sequentially in a hardware triggered mode.
2. Triggering Master in a software triggered mode.
B. TRANSFERRING FILES
1. The data is stored in file(s) with max cap placed at 2 GB.
2. The files can be retrieved from the SSD (/mnt/ssd folder) using WinSCP.
Note: Update lines 18 to 49 as needed before using this script.
--
Note: "capture_time" is a timeout for this script alone to exit - it does not control the
actual duration of capture. The actual capture duration depends on the configured frame time
and number of frames.
--]]
capture_time = 2000 -- ms
inter_loop_time = 2000 -- ms
num_loops = 1
--[[
Note: Change the following three parameters as desired:
1. n_files_allocation: is the number of files to preallocate on the SSD.
This improves capture reliability by not having frame drops while switching files.
The tradeoff is that each file is a fixed 2047 MB even if a smaller number of frames are captured.
Pre-allocate as many files as needed based on (size_per_frame * number_of_frames) to be captured.
2. data_packaging: select whether to use 16-bit ADC data as is, or drop 4 lsbits and save 4*12-bit numbers in a packed form
This allows a higher frame rate to be achieved, at the expense of some post-processing to unpack the data later.
(Matlab should still be able to unpack the data using the '*ubit12' argument to fread instead of 'uint16')
The default is no-packing, for simplicity
3. capture_directory: is the filename under which captures are stored on the SSD
and is also the directory to which files will be transferred back to the host
The captures are copied to the PostProc folder within mmWave Studio
Note: If this script is called multiple times without changing the directory name, then all
captured files will be in the same directory with filename suffixes incremented automatically.
It may be hard to know which captured files correspond to which run of the script.
Note: It is strongly recommended to change this directory name between captures.
