    Good stuff… Thanks… I’ll read through the tech report..

    Perfect work indeed

    I would like to ask you about the target support package tool when you programming your DSP using Matlab, how you can monitor or see any variable during real time implementation of the system, I mean if you have internal variable in your simulink and this variable is changing with time. The other question is how you can find the maximum sampling frequency of your system to insure all the program are implemented during this time?

    Best Regards

    First think you need to do is determine a realistic control loop speed, i.e., how quickly do you think your control can sample then solve all the equations? I recommend create a discrete-time model with a very slow sample rate, toggle pins on the dsp to make extra sure you are calculating everything fast enough. Start decreasing sample time until you notice calculates are not finishing before the next timer interrupt. I think real-time workshop calls them steps. The signals showing up on down sampled simulink signals sent to the computer using RTDX. I hope that answers your questions.
