"If I remove power from VS2, you can hear the the harmonic of the oscillators, of stepper motor #1 energize just as the voltage displayed in the Analog I/O window for Snap0 drops below 1.3V" I do hear a high pitched whine when the snap amp is functioning. Somewhere I read the PWM is at 32khz, obviou...

I did not know the amp had a fault led. There are two on the PCB and one LED is blinking about a 1 second interval, all the time. I have tried level 10, with no noticeable change. I*'m not sure if the Snap Amp is 50% defective and no idea how to test it. I really was hoping something simple would st...

Hi Tom, Yes 1 thru 8 was a typo. The configuration is pretty much the "SnapAmp 2 Steppers.c" example with a couple of values changed. StepperAmplitude = 25; // To reduce heat while testing WriteSnapAmp(SNAP0+SNAP_PEAK_CUR_LIMIT0,9); WriteSnapAmp(SNAP0+SNAP_PEAK_CUR_LIMIT1,9); If I remove power from ...

I'm hoping I've overlooked something simple. The problem that I’m having. I have been able to successfully control of one stepper motor #1, which is connected to the Snap Amp (Out1, Out2, Out3, Out4) with a 48 Volt 12amp power supply connected to VS1 and GND. I have had no success in controlling ste...
