Communicate between PC and PIC via RS232 standard using Matlab (GUI, IO).

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.

You can find more detail in website:

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.

I think your project base on USART. It is the same as communicate with RS232 not different.The only different is wire and wireless.
