IoT-Maker-Den-Mono-.NET-on-Raspberry-Pi2

IoT Maker Den migrated and implemented on Mono .NET on Raspberry Pi 2

Documentation in progress

Please refer to the IoT Maker Den on .NET Micro Framework on Netduino documentaion

Running Maker Den on Raspberry Pi

This project can run with or without the configured prototype shield. See the code examples below for running barebones or with a fully configured Maker Den prototype shield.

#Setting up Mono on Raspberry Pi

More to come, but for now refer to this excellent article of setting up Mono on your Raspberry Pi.Getting started with the Raspberry Pi 2, for .NET developers

What is the Internet of Things Solution Accelerator?

The Internet of Things Solution Accelerator for the .NET Micro Framework provides a pluggable foundation to support sensors, actuators, data serialisation, communications, and command and control.

Extensible/pluggable framework supporting

1. Sensors

• Physical: Light, Sound, Temperature, CPU Temperature
• Virtual: Memory Usage, Diagnostics
• Sensor data serialised to a JSON schema

2. Actuators

• LED, Relay
• Adafruit Mini 0.8" 8x8 LED Matrix
  • Low and high level pixel frame transformation primitives
  • alphanumeric character and symbol drawing and scrolling capability

3. Command and Control

• Control relays, send messages to a Adafruit Mini 8x8 Matrix etc via the communications layer

4. Communications

• Pluggable – currently implemented on MQTT (Mosquitto MQTT Server running on Azure)

5. Supported and Tested

• Raspberry Pi 2 and B+
• Visual Studio 2013 Community Edition, Express Desktop, Std, Pro and above
• Targets .NET 4.5 on Mono .NET on Raspberry Pi

IoT Dashboard

The IoT Dashboard allows you to visualise the data streamed to Azure.

You can install the IoT Dashboard from here. Note, you will need to allow to run from unknown publisher.

Programming Models

Declarative Event Driven Model

Raspbery Pi Barebones without the Maker Den Prototype Board

Connect Ethernet port to router/internet.

This example does the following

1. Start network services and posts sensor data via MQTT to IoT Dashboard

2. Loads Sys for remote shutdown and reboot via MQTT,

3. Reports CPU Temperature,

4. Reports .NET Working set memory.

    using Glovebox.Adafruit.Mini8x8Matrix;
    using Glovebox.RaspberryPi.IO.Actuators;
    using Glovebox.RaspberryPi.IO.Sensors;
    using Raspberry.IO.GeneralPurpose;
    using System.Threading;
   
    namespace MakerDenMono {
    	class MainClass : MakerBaseIoT {
    		public static void Main(string[] args) {
   
    			InitializeDrivers();
   
    			StartNetworkServices("mono", true);
   
    			using (Sys sys = new Sys("rpi"))
    			using (SensorCPUTemp cpuTemp = new SensorCPUTemp(10000, "cpu01"))
    			using (SensorMemory mem = new SensorMemory(2000, "mem01")) {
   
    				cpuTemp.OnBeforeMeasurement += OnBeforeMeasure;
    				cpuTemp.OnAfterMeasurement += OnMeasureCompleted;
   
    				mem.OnBeforeMeasurement += OnBeforeMeasure;
