Hi everybody.

I think that Matlab is a famous software is used in Automatic control, Electric and Communication, .... because of its benefits.


So I am pleased to give you a application I have written by myself. Its interface like a figure in attached files.
To use my application, you need to do step by step as following:

• Download file named Matlab_RS232 Communication.zip. Unzip it to one folder.
• Open Matlab, type command:

• GUI

• After Graphic User Interface display, chose "Open existing project" (something like that) and browse to file named: RS232_Communication.fig.

As my application is kind of open source,you can edit it for your purpose. There are some function you should edit:

• function ByteAvailable_Callback(obj, event)
  The program will call this function when a byte appear in Input buffer.
• function OutputEmpty_Callback(obj, event)
• function Error_Callback (obj, event)
• function PinStatus_Callback(obj, event)
• function Timer_Callback (obj,event)
• function BreakInterrupt_Callback(obj, event)

To find further information about GUI, you can use Help with keyword: GUI or find "Graphic User Interface".

Type:

 >>help serial

for more details about Serial Object.

The application was tested by some members in this forum. But if it has any problems, do not hesitate to contact me or reply.

Note: Only members can see figure and download enclosed files.


Best wishes to you.
