PC与51单片机串口通信。包括单片机内运行的程序,及MATLAB调试助手简易程序等!

% --- Executes during object creation, after setting all properties. function edit1_CreateFcn(hObject, eventdata, handles) if ispc && isequal(get(hObject,'BackgroundColor'),...

get(0,'defaultUicontrolBackgroundColor'))

set(hObject,'BackgroundColor','white'); end

function mycallback(obj,event,handles)%接收事件回调函数 global rcv; global str;
