Other Parts Discussed in Thread: TMS320F28069M, CONTROLSUITE

Is it possible to rotate a stepper motor at 350 rpm at 1/512 microstepping using tms320f28069m. If the answer is yes can anyone provide me supporting code. I use the PM_sensorless.c to achieve the target but at 1/512 microstepping maximum rpm is 3 and unable to increase ISR_FREQUENCY beyond 23 khz.

F28069M can be implemented micro-stepping for a stepper motor, you can refer to the example project in ControlSUITE as below if you installed it in a default floder. The example is based on F28035, it can be easily migrated to F2806x.
