Hi, evry!

In RAMPGEN.H there is StepAngleMax parameter wich is =0 as a default.

Further, we have Angle parameter wich is always =0 either because of StepAngleMax is always =0.

Looks like there is no ramp generation...

Unfortunately, I don't have hardware to test it imperically.

Thanks everyone who will fade away my doubts.

rampgen objects rg1, rg2 are initialized in the following two lines

rg1.StepAngleMax = _IQ(BASE_FREQ*T);

rg2.StepAngleMax = _IQ(BASE_FREQ*T);

therefore, they are not 0 afterwards.

Hope that helps.

Thanks, Louis.

And will You please point the file they're initialized in?
