I am trying to run my stepper motor with wave drive. I developed a vissim model and when i am trying to develop a debug diagram, the Output of model and debug diagram doesn't coincide. I am attaching both the files and their outputs in document file.
- Does my debug diagram and my model should have same Time step?
- The max frequency is 10hz and the given sample rate is 10 times of frequency (satisfying Nyquist criteria), even though the output differs . If I change the sample rate more than 100hz in my target interface, it changes the nature of output-- Reason
I wonder if there is a block that can let me simulate the possible waveforms I can get from the ePWM block. If there is one, where can I find it?
I'd like to find the time derivative of a measured input signal to a F28069 Piccolo. Is there a standard fixed-point solution for this?
I have a Delfino F28335 and it does floating point in the hardware. Which is better, fixed-point or floating point?
Can I flash directly from VisSim?
I have to say that I am very pleased with Texas Instruments latest round of DSP and microprocessor development kits. They have done an amazing job of taking the cost out of sophisticated embedded development. At one time, the JTAG pod alone cost $1500, now it is included free with the kit. They have the latest TI C2000 parts: F28335 and F28035, real-time JTAG connection to the PC, high quality analog sensors, and a very good C compiler.
