How to resize bitmap images using C++ [shorts #2]

Since 2016, I’ve always returned back to my Macintosh Classic CRT build, constantly trying to refine the project and make it easier to reproduce my results. In my latest attempt, I used a Raspberry Pi to communicate with the monitor. While that method worked like a charm for me, others have reported a few problems they’ve encountered and possible solutions. In my next attempt to finally get this project right, I decided to go down another path. Without going into too much detail here, the new method required me to implement a simple scaling and dithering algorithm in C++. This short article discusses my image scaling solution in C++.

Getting started with the Seeedstudio XIAO

This video takes a look at the Seeedstudio XIAO board. In it, I unbox the device, take a look around it, assemble it, and I also show you how to prepare the Arduino IDE to get the XIAO up and running in no time!

How to use interrupts on the LPC55S69 powered Okdo E1

In the last article, I summarized the process of enabling and using GPIO pins on the Okdo E1 by configuring the MCU in the MCUXpresso IDE. This time, I’ll enable pin interrupts that allow an application to react to various events.

How to use the GPIO pins on the LPC55S69 powered Okdo E1

Over the last couple of years, I’ve utilized a few different Arduino, Raspberry Pi, and other Linux based hobbyist development boards, like the BeagleBone Black, for many of my projects. I, however, never used other microcontroller boards that weren’t Arduino compatible. Recently, I started experimenting with the Okdo E1, a development board that’s powered by the LPC55S69, a very capable NXP microcontroller.

Arduino MKR Vidor 4000 Verilog FPGA and MCU hello world tutorial

This article discusses how user code can be uploaded to both, the MCU and the FPGA, of the Arduino MKR Vidor 4000. Some time ago, I wrote this summary of the topic which, however, didn’t include an easy to follow tutorial. Instead, it was more of an outline aimed at more experienced users. However, today I tried to re-create the steps, and I noticed that the original article wasn’t as simple to follow for beginners as I’d have liked it to be.

Simple Swinging Power Lines and Ropes in Unity

I wanted to create dynamic power lines for a game that I’ve been working on in Unity for the last few weeks. I couldn’t find a solution that satisfied my requirements, and so I decided to implement a custom solution, which I wanted to share with you.

How to build a responsive Angular Frontend

Smartphones and tablet computers have become more and more important over the last couple of years. Today, it’s almost impossible to image the internet without websites that function and look great on almost any screen. However, with business apps, that is often not the case. And, to be fair, it’s often also not required. In my case, however, I wanted to add basic responsive support for an Angular frontent that I’m working on, and in this article, I’d like to present the method that I used.
