I am testing a stepper motor (PKP262MD28A oriental) with ST motor driver L6470. But the motor only runs at low speed and high speed.

I am testing a stepper motor (PKP264MD28A oriental) with ST motor driver L6470.  But the motor only runs at low speed and high speed. Now less than 400pps and more than 6000pps are stable but the motor is step-out state or very unstable during 400 to...

Hello I am trying to run a motor using steval stspin32F0 and i came across the mooc videos to troubleshoot the problems. But I need to measure currents from the DAC it seems for the back emf currents but i have no clue where the DAC is on this board

STP08DP05 Current Variation in a single output

BackgroundI'm using STP08DP05 to control the current (20mA) through some LEDs in my design. I'm using these for illumination purposes while I take an image. I'm finding some variation in the brightness of my image, and I think it might to do with sli...

Parallel DC-DC Converters...conflicts

I am trying to figure out if I can have a MPPT charge controller in parallel with a DC-DC converter (sharing a solar array). I realize the MPPT charge controller is a DC-DC converter and I am also aware that two MPPTs in parallel will cause a possibl...
