How To Program A Really Cheap Microcontroller
There are rumors of a cheap chip that does USB natively, has an Open Source toolchain, and costs a quarter. These aren’t rumors: you can buy the CH552 microcontroller right now. Surprisingly, there aren’t many people picking up this cheap chip for their next project. If there’s no original projects using this chip, no one is going to use this chip. Catch 22, and all that.
Like a generous god, [Aaron Christophel] has got your back with a working example of programming this cheap chip, and doing something useful with it. It blinks LEDs, it writes to an I2C display, …read more

Crash your code – Lessons Learned From Debugging Things That Should Never Happen™
Let’s be honest, no one likes to see their program crash. It’s a clear sign that something is wrong with our code, and that’s a truth we don’t like to see. We try our best to avoid such a situation, and we’ve seen how compiler warnings and other static code analysis tools can help us to detect and prevent possible flaws in our code, which could otherwise lead to its demise. But what if I told you that crashing your program is actually a great way to improve its overall quality? Now, this obviously sounds a bit counterintuitive, after all …read more
A Portal Port Programmed For Platforms Of The Past
If you still have a Commodore 64 and it’s gathering dust, don’t sell it to a collector on eBay just yet. There’s still some homebrew game development happening from a small group of programmers dedicated to this classic system. The latest is a Portal-like game from [Jamie Fuller] which looks like a blast.
The Commodore doesn’t have quite the same specs of a Playstation, but that’s no reason to skip playing this version. It has the same style of puzzles where the player will need to shoot portals and manipulate objects in order to get to the goals. GLaDOS even …read more

A Whole Other Kind Of Graphical Programming
Java isn’t everyone’s cup of tea. With all its boilerplate and overhead, you’re almost always better off with a proper IDE that handles everything under the hood for you. However, if you learn a new language, you don’t really want to be bothered setting up a clunky and complex IDE. If only you could use a simple, standard Windows program that you are most likely already familiar with. This wish led [RubbaBoy] to create the MSPaintIDE, a Java development environment that let’s you write your code in — yes — MS Paint.
If you’re thinking now that you will end …read more

Become The Rockstar Developer You’ve Always Dreamed Of Being
If you have ever worked in software-related industries, the chances are that the word “Rockstar” will elicit a visceral reaction. It’s a word used by a Certain Type Of Manager for an elite software developer who’s so 1337 they don’t play by the rules of ordinary mortals. In reality it’s use is invariably an indication of trouble ahead, either from clueless startups or troublesome rockstar developers making a toxic atmosphere for the mere members of the backing band. Hackaday has a team that brings together a huge breadth of experience, and we’ve been there.
Would you like to be a …read more
Friday Hack Chat: Making Programming Easier
There is a long history of graphical programming languages. Some people don’t like to code, and for them, graphical programming languages replace semicolons and brackets with easy-to-understand boxes and wires.
This Friday, we’re going to be talking about graphical programming languages with [Boian Mitov]. He’s a software developer, founder of Mitov Software, and the creator of Visuino, a graphical programming language for the embedded domain. He specialized in video, audio, DSP, DAQ, industrial automation, communications, computer vision, artificial intelligence, as well as parallel and distributed computing. [Boian] is the author of the OpenWire open source technology, the IGDI+ open source …read more

State Your Intentions More Clearly With State Machines
To the uninitiated the words ‘State machine’ sound like something scarily big and complex. They aren’t (necessarily) and can be quite useful. In fact, state machines are no physical machines but a model of processes. They link the states a system can be in with allowed transitions. For example a media player when stopped can change to play or open another file. While playing, it can go to pause, stop, reverse, fast forward and so on. A state machine creates a map of all states and how they are connected. It is an abstract tool hat offers a graphical approach …read more

Running Programs On Paper
It’s a simple fact that most programs created for the personal computer involve the same methods of interaction, almost regardless of purpose. Word processors, graphics utilities, even games – the vast majority of interaction is performed through a keyboard and mouse. However, sometimes it can be fun to experiment with alternative technologies for users to interact with code – Paper Programs is an exciting way to do just that.
Paper Programs is a combination of a variety of existing technologies to create a way of interacting with code which is highly tangible. The setup consists of a projector, and a …read more
