Introduction

This post is about a decade old problem: how to properly encode command line arguments. Properly encoding string arguments into a long command line should not be a complicated issue. However, I have seen multiple situations where people wrongfully assume that wrapping each argument with double quotes is ‘safe enough’ for most situations. That is simply not true.

This article is about the C++ library libArgvCodec which properly encodes and decodes command line parameters.

Introduction

The following article is about my new c++ library: libVariant. The library allows one to easily store/encapsulate a value of any c++ type into an instance of type Variant. The library is useful for declaring objects, interfaces, APIs or plugins to be type-independent.

Purpose

The libVariant library allows one to create an instance of Variant class. The class is a type safe and value safe union between all known basic c++ types. An instance of a Variant class encapsulates a single value of any c++ type: signed and unsigned integers, floating points & strings.

Introduction

The following article is written in order to demonstrate how my arduino libraries libRtttl & AnyRtttl can be used to convert arduino code (tone() and delay() functions calls) into actual RTTTL melodies.

This article shows how to convert ‘Game of Throne theme’, ‘Star Wars - The imperial March’ and most Super Mario Bros. sound themes (Main theme, 1-up life sound, Flagpole fanfare, Death and Game Over sounds) into actual playable RTTTL melodies.

À chaque fois que je travail en graphisme et que je dois ajouter du texte à une image, je me retrouve toujours avec le même problème: “Comment faire pour identifier rapidement la meilleure police pour mon affiche ?”

Je crois maintenant avoir finalement trouver la solution à ce problème.

Voici un script pour Microsoft Word qui permet de générer n’importe quelle exemple de texte avec toutes les polices de votre ordinateur.

Introduction

The reason I started this project is because I recently had a bad experience flying a quadcopter too far from me until I was not able to distinguish if the quad was facing me or not. It does not require much distance before a quadcopter looks like a tiny black dot in the sky. Basically, I lost orientation of the quad and I had to land way too far from my takeoff location.

Please note that csvplot source code is now moved to GitHub. Source code can be downloaded from the project’s GitHub page.

Purpose

I do software prototyping using a wide range of programming language. I often have to generate data that changes over time which is mostly displayed in a grid format. However, that’s not the best way to understand how the data changes over time compared to plotting the data to a graph.

Introduction

The following article is about my simplest library that I wrote for the arduino: SoftTimers. The SoftTimers arduino library allows one to properly time multiple events and know when each “timer” expires meaning that an action is required.

When I first learned programming the arduino, I learned the “hello world” of the arduino: turning a LED on and off. As expected, I used delay() to define how long the LED should be on and off.

Introduction

The following article is about another library that I have written: libRtttl is a c++ library for manipulating the RTTTL audio format.

See this post for a quick recall of the RTTTL format.

Edit: for a better understanding and examples of what libRTTTL can do, please see this post: How to convert arduino code to actual RTTTL melodies using libRtttl and AnyRtttl.

Purpose

RTTTL songs available on the internet are not optimized for the smallest size. Still they are readable by a human but they are far from optimized for the arduino embedded device. Most RTTTL song can be optimized (without quality loss) and have their size reduced by ~20%. Conversion to binary allows even better compression but it wont be human readable anymore.

Introduction

The following article is about yet another Arduino library that I have written. AnyRtttl is a feature rich arduino library for playing RTTTL melodies. The library offers much more interesting features than relying on the widely available void play_rtttl(char *p) function. The AnyRtttl is a feature rich library which supports all best RTTTL features.

Introduction

Please note that win32Arduino source code is now moved to GitHub. Source code can be downloaded from the project’s GitHub page.

After implementing many arduino library, I realized that unit testing a library is harder than I though. Most of the time, the library does not even require advanced arduino functionalities and could be tested outside of the arduino platform.

The win32Arduino is a solution to this issue.
