For his entry into the 2019 Hackaday Prize, [Tobius Daichi] is working on adding some motion control capabilities to everyone’s favorite Linux SBC. His 3+Pi board attaches to the Raspberry Pi’s GPIO ...

Two-chip designs combining a microcontroller or DSP with a highly integrated driver IC simplify the design of a stepper-motor controller, while also enabling sophisticated control features that would ...

It’s fair to say that building electronic gadgets is easier now than it ever has been in the past. With low-cost modular components, there’s often just a couple dozen lines of code and a few jumper ...

grbl is stepper motor controller firmware for three-axis cnc machines, intended to run on Arduinos with a motor driver add-on board. Engineer in Wonderland cnc-related blogs are indexed here It is the ...

To run a stepper motor smoothly, it's necessary to apply linear acceleration. However, conventional algorithms to generate linear acceleration require complicated mathematics, which makes it difficult ...

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

Element 14 has published a new project to their “Presents” YouTube channel providing details on how you can build your very own DIY DSLR motorised camera zoom system to remove the need to forever ...

The Stellaris LM3S818 controlCARD module included in the kit has the required firmware pre-programmed in flash memory to run TI's new InstaSPIN™-BLDC solution out ...
