• IoT Central model export/import issue

    I ran into an issue on IoT Central today where I exported a model, deleted it, tried to re-import and it failed. I discovered the issue after some manual manipulation of the exported JSON and it was related to the generated @id property for the request object of a command capability.

    I came across a sweet tool for converting HTML pages to Markdown - it's not perfect, but is a good start:

  • Customizing the Visual Studio Code Integrated Terminal

    I continually forget how to customize the integrated terminal in VSCode, so I will capture it here for posterity.

  • .NET Core and GPIO on the Raspberry PI - LEDs and GPIO

    In the previous article, I explored installing and running .NET Core 3.0 on a Raspberry PI running Raspbian. In this article I intend to create a simple console application that will interact with the GPIO and flash an LED.

  • Exploring IoT on Raspberry PI 3 V2 with .NET/C#

    While working on various courses for Azure IoT, I have had a bunch of experience working with C/C++ and Python on Linux and C#/UWP on Windows 10 IoT Core. However I have noticed that the Raspberry Pi isn't necessarily an ideal platform for Windows 10 Core - in fact the later models, including the Raspberry Pi 4, are not yet supported. So, if I want to explore IoT in C# on the Raspberry Pi, I need to look at .NET Core.

    The Windows 10 April 2018 Update includes a new set of APIs in the Composition namespace that support various geometries such as lines, ellipses, rectangles and paths. However, during the insider cycle, it wasn’t possible to create arbitrary paths as there was a reliance on an implementation of IGeometrySource2D that could not be found. Fast forward until today when a new version of the Win2D package has been released – V1.22.0 and now we can make use of CanvasGeometry class to create our paths.
