For mechanical systems, the smoothing element of the system is often the inertia of the system – meaning how quickly the system reacts to a change in input. This is covered in our Buck and Boost Converter articles using the concepts of a Flywheel / Merry-Go-Round. Imagine we added a wa...
Also, plugging the PWM module back in, doesn't solve the issue right away all the time, even at the beginning. It sometimes needs to "rest" for a bit. Then, once plugged in again it resumes working again like before.. meaning, only for the first second or so, until it goes ...
At 0% the signal is constantly LOW, essentially meaning no voltage at all. Obviously, this causes the motor to stop.For a detailed explanation of PWM please see the article “Controlling DC Motors with the L298N Dual H-Bridge and an Arduino”. ...

Well, here is my latest suggestion (right, modelled in LTspice, but not yet tested IRL): It is feedback-based, and forms a PWM-locked-loop. Rail-to-rail op-amp U2 is wired as an oscillator that generates, for the purposes of this circuit, a sawtooth wa...
Input and output mounting pads/holes are all doubled, meaning it should be easy to hook them up in various ways. A standard USB plug fits juuust barely to the Vin pins if you extract the data pins. As there’s no mechanical support, I wouldn’t recommend doing that as a pe...
It is usually not too difficult to answer this question, because the central element in a standard PWM hardware block is an N-bit counter that controls the width of the pulse, meaning that the equivalent DAC resolution is 2N. For example, the datasheet for Atmel’s SAM4S microcontroller ...
Event n2 gets always executed, meaning that the counter timeouts. The error must therefore be in the edge detection events, although I can't quite find it. Any possible advice or suggestion? 0 Kudos Reply 06-15-2016 10:04 AM 3,140 Views lpcware NXP Employee Content originally pos...
I’ve been meaning to move it over to simplefoc. Next step is moving away from this square wave 6 step to sinusoidal with SimpleFOC and yes - I’m wondering the same as to how to avoid short circuiting high and low. I think @Antun_Skuric has already said that the solution is ...
