IoT and managed sensor interface with WEC2013

In my last blog post I showed how to transfer IoT data over the network using the M2MQTT library. But how, you may ask, do you acquire the data in the first place? Well, chances are you have some kind of sensor, be it temperature, pressure, accelerometer or what have you. These sensors, more than likely, interface to the IoT node processor via some kind of bus. It could be I2C, SPI, CAN, LIN or any number of others in the alphabet soup. By far the two most popular low level sensor buses are I2C and SPI. I2C stands for Inter-Integrated Circuit and was invented by Philips Semiconductor (now NXP Semiconductor), SPI stand for Serial Peripheral Interface invented by Motorola. In this example I will show how we can interface to these buses using managed code (C#) in Visual Studio 2013. I will use the BeagleBone Black as the platform running Windows Embedded Compact 2013. A prebuilt demo image is available at my Codeplex site along with all the source code for the example. To start I wired a prototyp ...
