Hi,
I'm experience some strange behavior when using the graph tool in CCS v5.3. I'm running the DRV8312-C2-KIT to evaluate the control performance with steep ramps. In the attached graph I've plotted (using the exported data) the speed reference (target) and the speed feedback from a quadrature encoder. As you can see there are some abrupt jumps both in the target ramp and the measured signal. I however doubt that the graph shows real values in those cases. Has anyone seen something similar? Even if I use a instantaneous step as target (i.e. no ramp) I sometimes observe this kid of glitch in the logged data. Does it maybe have anything to do with sampling rate or buffer size?
