（一）

% 你可以根据实际的分隔符进行设置

opts = delimitedTextImportOptions('Delimiter', ',');
% 读入(.txt)文档，文档以分隔符进行分离 -> table

data = readtable('D:\QT_Project\servo\recvData.txt', opts);
% table -> cell

dataMatrix = table2array(data);

% cell -> double

sendData_cell = dataMatrix(:, 2);

sendData = str2num(char(sendData_cell));

recvData_cell = dataMatrix(:, 3);

recvData = str2num(char(recvData_cell));

interval_cell = dataMatrix(:, 14);

interval1 = str2num(char(interval_cell));

interval_value = interval1(1);

% 生成自然数序列

x = (1:length(sendData)) * (interval_value/1000);
% 绘制sendData曲线

plot(x, sendData, 'r');

hold on;
% 绘制recvData曲线

plot(x, recvData, 'b');
% 添加图例

legend('sendServo', 'recvServo');

title('舵机1');
