AWR1843BOOST: AWR1843BOOST串口实时读取数据

您好，目前我需要做的是利用AWR1843BOOST串口实时读取数据，

问题1：根据这个文件串口读取数据www.ti.com.cn/…/zhcab69.pdf

请问这个文件相关资源在哪里可以获取？

问题二：目前板子烧录的程序是SDK3.6中XWR1843的demo.bin文件，目前也通过MATLAB写了一个串口的读取数据程序但是总是数据采集不到请问如何解决？下面是我的代码和雷达前端参数配置 这个参数我用mmwave studio可以实现采集，

clc;clear
clearvars; close all
delete(instrfind);
% 配置参数
configfile = "D:\seven\Desktop\采集数据串口\xxxw.cfg";

% 读取cfg文件
config = cell(1,100);
fid = fopen(configfile, 'r');
if fid == -1fprintf('File %s not found!\n', configfile);return;
elsefprintf('Opening configuration file %s ...\n', configfile);
end
tline = fgetl(fid);
k=1;
while ischar(tline)config{k} = tline;tline = fgetl(fid);k = k + 1;
end
config = config(1:k-1);
fclose(fid);


%%%% UART COM PORT:
comPortString_UART = 'COM4';
UART_sphandle = serial(comPortString_UART,'BaudRate',115200);
set(UART_sphandle,'Parity','none')
set(UART_sphandle,'Terminator','LF')
fopen(UART_sphandle);

%%%% DATA COM PORT:
comPortString_data = 'COM3';
DATA_sphandle = serial(comPortString_data,'BaudRate',921600);
set(DATA_sphandle,'Terminator', '');
set(DATA_sphandle,'InputBufferSize', 65536);
set(DATA_sphandle,'Timeout',10);
set(DATA_sphandle,'ErrorFcn',@dispError);
set(DATA_sphandle,'BytesAvailableFcnMode','byte');
set(DATA_sphandle,'BytesAvailableFcnCount', 2^16+1);%BYTES_AVAILABLE_FCN_CNT);
set(DATA_sphandle,'BytesAvailableFcn',@readUartCallbackFcn);
fopen(DATA_sphandle);

% 
mmwDemoCliPrompt = char('mmwDemo:/>');

%Send CLI configuration to AWR1843
fprintf('Sending configuration from %s file to AWR1843 ...\n', configfile);
for k=1:length(config)command = config{k};fprintf(UART_sphandle, command);fprintf('%s\n', command);echo = fgetl(UART_sphandle); % Get an echo of a commanddone = fgetl(UART_sphandle); % Get "Done"prompt = fread(UART_sphandle, size(mmwDemoCliPrompt,2)); % Get the prompt back
end

% 读取数据
RX_num = 4;
TX_num = 1;
Per_Frame_Chirps_Num =10;
ADC_Sample_Num = 256;

% 读取数据
[bytevec, byteCount] = fread(DATA_sphandle, bytesToRead,RX_num*TX_num*Per_Frame_Chirps_Num*ADC_Sample_Num*2*2, 'uint8');

问题三：另外如何实现实时采集数据，我目前想法是设置无限制帧，每次读取一定帧数内容，保存在缓存区内，在继续读取数据，缓存区单独存放在另外变量中，但具体还不知道如何实现。有没有相关文档？
