I've made a GUI in matlab to read data via RS232 and plot
it to a graph. The only problem is I have to keep pressing
a button to send a 'getdata' command to my microcontroller
via RS232 so it sends the data back. I want to implement
this in continuously/real time so I don't have to keep
pressing a button to communicate with my device. I've
written while loops and that just freezes my program, i've
also tried a checkbox so if it's checked it gets data and
that also freezes the GUI.
Just wanted to know if there is a successful way to get
real time data without crashing my program, thanks

Hi Jim, unfortunately I can't help you out but I also am
interested in plotting RS232 transported data would you be
able to share your code with me?
thnaks

You may look at the post "Read Serial Port from RS232
Continuously" under serial port tag.

hi jim, i m doin a similiar gui, can u share wit me ur
codes, i will b very grateful! and this my email:

I am working to get an FPGA to communicate through rs232 and
read it into Matlab. If you wouldn't mind sharing your code
or giving some hints on where to start I would appreciate
it so much. Thank you.
