Windows 10 IoT-Core: Take Two (RPI3)

After an absence from significant IoT-Core activity, whilst working on a significant phone app (as blogged here) I’m back in the IoT-Core space. Things have changed for the better so here goes.  This blog covers my experiences with getting a RPI3 going with the latest Technical Preview build. Tools are now available to simplify setup and there is now a Remote Viewer.  As a test UWP app, I have used (after a small modification) the Icons app on Codeplex,  Universal Windows 10 SDK App Icons app as blogged in a previous blog. The app was modified because popups (as in MessageBox) are not supported in IoT-Core (Use thereof can cause an app crash in later OS versions). This feature change is covered.

More GEMS: Kept getting Network Access Required in a Universal App–An hr or 2 later!

I’m creating a Windows 10 Universal Phone App that talks to a Web Service to post an entity (object) in Microsoft SQL Server running on the same machine as the Web Service. Initially did all including the app on my laptop using localhost as the network target. Solved the SQL Server credentials .. OK. But when I switch to using the laptop’s system name or its IP address (all still running on same machine) got Network Access Required error.

Little GEMS: XAML page not linked to its Codebehind Page .. Solution

 

In developing a Universal Windows app, when you add an existing XAML and its Codebehind page, they often end up unlinked in the Solution Explorer. This limits the ability to autogenrate event handlers in the codebehind page for UI elements.Spaso Lazarevic has a good solution that involves a little editing of the project file.

Win 10–IoT Core: Visual Studio 2015 Update 1 App Deployment and Debug Requirements -2

The previous blog explained what needs to be done to be able to deploy and debug apps with latest build for IoT-Core (Build 10586).

Win 10 IoT Core: Raspberry Pi 2 Peripherals – Serial (Update 3)

There are currently 2 reserved GPIO pins on the RPI2 that ordinarily are SOC (I call native) serial. A future Tx and Rx  but not at the moment. Serial is achieved on the RPI2 with Win 10 IoT Core via a USB-Serial device connected to a Host USB port on the RPI2. There are though limitations in that the widely used FTDI chipset is not supported by Microsoft, although we have a solution. An alternative is over Bluetooth but there is an issue there.
