基于Matlab GUI的單片機(jī)串口與PC的通信附源碼

ID:436521 · 發(fā)表于 2018-11-30 14:38

我也是最近學(xué)習(xí)單片機(jī)和MATLAB的小白平時(shí)在看學(xué)習(xí)的時(shí)候下載了一些有價(jià)值的參考文獻(xiàn)

概述

采用51單片機(jī)，atmel的STC89C52RC芯片，主要用到的是七段數(shù)碼管用來做一個(gè)時(shí)鐘，程序編寫軟件為keil，燒錄軟件為STC-ISP 4.88，串口調(diào)試軟件用的是sscom42。
運(yùn)用Matlab的GUI工具編輯一個(gè)可視化界面，用以跟單片機(jī)進(jìn)行串口通信

實(shí)現(xiàn)功能

運(yùn)用keil編寫時(shí)鐘程序，燒錄到單片機(jī)中，時(shí)鐘程序?qū)崿F(xiàn)的功能是實(shí)現(xiàn)時(shí)鐘的顯示，并且能用開發(fā)板上的三個(gè)按鈕進(jìn)行時(shí)鐘的修改，一個(gè)按鈕進(jìn)入修改模式，另兩個(gè)實(shí)現(xiàn)時(shí)間的增減。
編輯GUI界面，實(shí)現(xiàn)對(duì)單片機(jī)的控制，其中，GUI界面通過串口能不斷的采樣開發(fā)板上時(shí)鐘的數(shù)值，并在GUI界面上進(jìn)行顯示。同樣的，可以通過GUI界面實(shí)現(xiàn)對(duì)開發(fā)板上時(shí)鐘的修改。

具體實(shí)現(xiàn)

開發(fā)板部分：

B) Matlab GUI界面的編輯

效果圖如下，操作說明：START點(diǎn)擊開始，采集單片機(jī)時(shí)鐘時(shí)間，ADJUST點(diǎn)擊進(jìn)入修改模式，同時(shí)單片機(jī)開發(fā)板亦會(huì)進(jìn)入修改模式，EXIT點(diǎn)擊關(guān)串口，退出界面，GET點(diǎn)擊獲取當(dāng)前值，另外一些輔助按鈕，滑塊按鈕都有各自功能，易于理解。

其中：

添加控件，具體略
START添加callback：

global s

s=serial('COM10');

fopen(s);

handles.timer = timer('TimerFcn',{@mycallback,handles}, 'Period',0.01,'ExecutionMode','FixedRate');

start(handles.timer);

ADJUST添加callback：

a=get(handles.text8,'String');

set(handles.text28,'String',a);

a=get(handles.text10,'String');

set(handles.text27,'String',a);

a=get(handles.text13,'String');

set(handles.text25,'String',a);

a=get(handles.text14,'String');

set(handles.text24,'String',a);

a=get(handles.text15,'String');

set(handles.text22,'String',a);

a=get(handles.text16,'String');

set(handles.text21,'String',a);

global s

fwrite(s,0);

EXIT添加callback：

global s

fclose(s);

close;

GET添加callback：

global s

a=fread(s,6);

set(handles.text8,'String',a(6));

set(handles.text10,'String',a(5));

set(handles.text13,'String',a(4));

set(handles.text14,'String',a(3));

set(handles.text15,'String',a(2));

set(handles.text16,'String',a(1));

調(diào)整時(shí)鐘調(diào)整分鐘調(diào)整秒鐘都添加callback：

global s

a=str2num(get(handles.edit1,'String'));

fwrite(s,a);

SLIDER1添加callback：

a=get(handles.slider1,'value');

set(handles.edit1,'String',a);

C)操作說明

1. 開發(fā)板上的按鈕修改時(shí)鐘顯示

2. 開發(fā)板上時(shí)鐘顯示

3. START前的開發(fā)板以及GUI界面，此時(shí)GUI界面的時(shí)鐘無顯示

4. START點(diǎn)擊后GUI有了顯示，與開發(fā)板顯示一致

5. ADJUST點(diǎn)擊后進(jìn)入修改模式，開發(fā)板同步進(jìn)入修改模式，同時(shí)GUI保留當(dāng)前時(shí)間quondam time，隨后分別調(diào)整秒鐘時(shí)鐘分鐘，可以用編輯框，也可以用滑塊.

6. 點(diǎn)擊調(diào)整時(shí)鐘后，顯示調(diào)整結(jié)束。

7. 同時(shí)，也可以用單片機(jī)上的按鈕調(diào)整時(shí)鐘，同時(shí)GUI會(huì)實(shí)時(shí)返回設(shè)置值

時(shí)鐘顯示程序如下（并且加入了串口接收部分）

你好，樓主，你的GUI里的text沒有28個(gè)吧，17個(gè)text,7個(gè)Pushbutton,1個(gè)edit?

說錯(cuò)了，20個(gè)text吧？
