This tutorial shows you how to connect a digitally addressable RGBW LED, SK6812, aka. NeoPixel to an STM32 using the HAL library, a timer for PWM and DMA

Use the image processing framework OpenCV with Qt GUI to create aesthetic color palettes: Guide on how to program an app in C++ that generates pinterestable colors from a picture & technical stuff under the hood you need to know about!

We used C++ to learn all the essentials and beauties of OOP. The language supplies us with tools to create classes, methods and everything that comes with it, like inheritance and polymorphism. Based on our knowledge of structs in C we’ve developed an understanding of how classes work. But can we write object oriented code in plain C?

OpenVFD incorporates a full Arduino® Uno® compatible platform and is built upon the Arduino® environment. The code is written in Arduino® C for everyone to understand, to take apart and to participate.

We show you how the OpenVFD software works!

While our last focus was on the IV-11 VFD tube - since we had to design a circuit that make the tubes glow and display the stuff we want it to, now the microcontroller is in the spotlight for adding fundamental features, such as a real time clock to the circuit.

The second part of the article...

This blog entry shows you what makes my VFD tube clock work and I will take you through the process of turning some tubes, parts and lines of code into a glowing tube clock. It's great and easy to follow this Instructable if you have some basic electronics knowledge already, but down't worry if not. I'll do my very best to keep everything short and simple. 

The first part is about the tube and...
