Purpose

The subversion application does not offer native support for identifying changes to subversion properties as easily as changes to files.

The purpose of this script is to allows a subversion user to find all revisions where a change to a specific property occurred. In other words, it’s a “show log for subversion properties”.

Note that svnpropertylog is only available for Windows and has been tested on Windows 7 only.

Introduction

The following article is yet another library that I have written. libMIDI is a c++ library for generating single tone melodies (monolithic melodies) in MIDI format.

Purpose

I mostly develop on the Windows platform. When I try to generate basic sounds and tone, I use the Microsoft Beep function. This API is quite old and is far from accurate when dealing with multiple short duration tones (less than 100ms). Also when you make two consecutive calls to the Beep() function will ear a tick sound between each calls.

Introduction

In a personal project, I wanted to add 2 new devices to an existing quadcopter. The quadcopter was equipped with a 6-channel receiver meaning I only had 1 spare channel to control the 2 devices:

The following article explains how I manage to solve the issue: How can I control more than one device using a single channel.

Introduction

The following arduino library was written to use the findings found during the Mapping RC Transmitter PWM signal to actual transmitter values article. All results were wrapped into a library for ease of use.

The RcReceiverSignal is an arduino library that allows one to read a signal sent from a Remote Controlled (RC) receiver.

Purpose

The RcReceiverSignal library allows one to easily configure an input pin to read a PWM signal sent from a RC receiver by attaching a RcReceiverSignal instance to a pin connected the receiver and automatically monitor each pulse sent by the receiver.

Introduction

Here is another arduino library that I have written.

As a desktop developer, I am not used to have memory (or even CPU) requirements as most developers will not look at memory consumption as an arduino developer would. Memory & CPU is cheap. If your application is struggling to run on today’s computer, it will run smoothly in 1-2 years.

As most arduino developers have faced, the amount of memory available on embedded devices is pretty limited. Having a way to save bits or our precious memory is interesting.

Introduction

The following article is about my first Arduino library that I have written. NonBlockingRTTTL is a non-blocking arduino library for playing RTTTL data.

EDIT: The NonBlockingRtttl arduino library is now moved to GitHub. Source code can be downloaded from the project’s GitHub page.

EDIT: NonBlockingRTTTL library is now available on the Arduino Library Manager.

Purpose

Most code that can be found on the internet that allows you to “play” an RTTTL string is build the same way: sequential calls to the tone() function followed by a delay() function. This type of implementation might be good for robots but not for realtime application or projects that needs to monitor pins while the song is playing.
