SurfPad: SurfPad States

As part of a series of articles on a set of projects targeted at using a Windows Surface device as the presentation layer for a RPI or Arduino device, this article views the apps as state machines and documents the app states coupling through message passing between them.

SurfPad: TCPIP Socket Connectivity

In the previous articles in this series, a UWP app was developed as an array of XAML buttons that acts as the UI for an app running on a remote embedded or IoT device. Once connected the remote app sends a configuration for the UI as a Json string. Connectivity between the UWP and remote apps over Bluetooth and USB Serial has been covered. In this article connectivity over network sockets is covered. The article includes 101 on TCPIP Network Sockets for UWP and Arduino.

Win 10 IoT-Core: Bluetooth Universal Windows Serial App–Update 1.2

This blog presents a Universal Windows App that connects to an embedded Bluetooth device over the Bluetooth Serial Profile using a genetic Bluetooth USB dongle. This app will run on both a Windows 10 IoT-Core devices such as a Raspberry PI2 and a Windows 10 Desktop. The blog covers in detail the key issues with pairing including where a passkey is required with a RPI2 as well as a Bluetooth primer. Update 1.2: One bug fix (was writing send text twice) and and one code improvement (menu returns DeviceInformation so no need to requery for it.)

Win 10 IoT Core: Raspberry Pi 2 Peripherals - Introduction

Whilst the Raspberry Pi 2 has extensibility through GPIO, I2C, SPI and Single wire, the main interface for adding off-the-shelf  peripherals is via USB. Unlike the desktop, there is though only a limited set of USB peripherals that can be used on the RPI2 running Windows 10 IoT in the first release. This series of articles looks at what is available and what the overarching issues are. The first Article is “Connected Devices”
