MPR121 Driver for Windows IoT Core/Raspberry Pi 2

I had a MPR121 in my tool box. After getting my Raspberry Pi 2 installed with Windows IoT Core, I wanted to get this MPR121 Capacitive touch break out board working with it. While Adafruit had a library for Arduino, there wasn’t an MPR121 Driver for Windows IoT Core readily available. So I wrote this Windows.IoT.Core.HWInterfaces.MPR121 library in C# that can be used with the Raspberry Pi. In addition to the sample app available in the Github repo,  I also  created a Touch sensitive Christmas tree using this library. This post describes a few things about the MPR121 library.

Arduino Yun Serial Port over TCP

Introduction

This article contains instructions on how to expose the Arduino Yun Serial Port over TCP.

Few days back, the Windows IOT challenge dropped in my twitter feed. While the challenge was very interesting, after poking around the web, I quickly realized that there is no Windows IoT Core for Arduino. Hopefully, sometime soon, Microsoft and Arduino will give us one.

Until then we will have to make do with Windows Remote Arduino. It is essentially a Firmata client library wrapped in a Windows Runtime Component. I had both an Arduino Uno and an Arduino Yun and I wanted to check out the Windows Remote Arduino interfacing.
