21469: Modifying variables in real-time & interfacing with custom GUI

Hello!

 

I have recently started working with an ADSP-21469 EZ-KIT Lite, and have been experimenting with implementing and running filters. For my next step, I would like to build a custom GUI for some of my applications so that I can modify program variables in real-time (i.e. filter gains, etc.).

 

I am comfortable with designing filters and building the GUI which would run on a PC. What I do not know is how to interface the two, say, have the PC-based program adjust a volatile int declared and initialized in the DSP code, while the DSP is running. I would like to know if there are any resources available that I can use to teach myself how to do this.

 

I'm sorry if there is already a post about this. I found this thread: http://ez.analog.com/message/5829#5829  though it hasn't answered my question entirely.

 

Thanks for your response!
