Bob Christie examines the EasyStepper concept for driving bipolar stepper motors using an integrated step and direction translator interface. A built-in translator makes devices incorporating ...
IC has two-line Step and Direction interface and efficient DMOS output. Thomas Rowan, Allegro Microsystems, Worcester, Mass. Most microstepping motor drivers require control lines for DACs to set the ...
LEDの明るさを変えたり、モーターの速さを調整したり。そんなときに使われるのが「PWM制御」という技術です。 この記事では、Raspberry Pi（ラズパイ）で使える2つのPWM制御方法「ソフトウェア制御」と「ハードウェア制御」について、初心者向けにわかり ...
The aim of the project is to implement torque control with a stepper motor using inexpensive hardware. The DRV8825’s internal microstep table is indexed using a timer output. Current amplitude (IChop) ...
I will have some spare time to work on this project, so I'm trying to understand low level motor driving, and in particular want to move from "open loop" mode (in actual design, if I correctly ...
