Arduino Bluetooth Keypad Utilities: Keypad Events UWP Library

An event driven Phone Keypad library. Includes KeyDown, KeyUp and KeyHoldling events to which event handlers can be attached in apps that use this library. Also includes a mechanism to fire those events from keypad scanning software. No hardware specific code though. These events mirror those events in the previous blog for the Arduino Keypad Event Scanning Sketch.  The next blog hooks the two up.

 

This blog demonstrates exemplary code for for implementing event table mechanisms for custom events, particularly if the events are driven by custom hardware.

Arduino Bluetooth Keypad Utilities: Event Keypad Sketch

This Sketch scans a phone keypad using the Keypad library and detects key pressed, released and held events. The events generate a string that is sent serially denoting the event and key.

Arduino Bluetooth Keypad Utilities: Bluetooth Echo Sketch

This Sketch is a slight modification of that published as a companion to the original General Bluetooth Serial App.

Arduino Bluetooth Keypad Utilities: UWP and Arduino Keypad Library on Codeplex

A library on Codeplex. Been a long time coming: Arduino sketches and UWP class libraries and apps, focused upon scanning a phone keypad as input (Bluetooth serial) to a UWP app running on a phone, desktop or IoT-Core device.

Windows Surface 2: Battery Pack Adapter

The Surface 2 has a weird power connector. That makes it difficult to charge it from a battery power pack. This blog outlines creating one from a  DC 12V 36W Car Charger Adapter for a Surface 2. Building it wasn’t too difficult.  This means I can now use my Surface 2 on long journeys without need to access main power to charge it. Cost about $A40 apart from the Surface and Power Bank.

Win 10 IoT-Core: “Windows 10 IOT-Core To Azure IoT Suite” presentation.

I did a presentation last Thursday for the Melbourne Azure Meetup.

The slides are at: http://www.slideshare.net/cedriverwiz/windows-10-iotcore-to-azure-iot-suite

The sample app (A UWP app communicating with an Azure IoT Hub using TPM): https://github.com/djaus2/AzureHubRegisterIoT

 

Whilst it does not go into great detail about Azure IoT Suite, it covers everything in the leader up to it. including:

  • Windows 10 IoT-Core
  • Internet of Things
  • Azure IoT Hub, including provisioning and device registration
  • Azure IoT Components

Win 10 IoT: AppX Installation Options–2

AppInstall can be used to install Appx packages on an IoT-Core device This blog covers an updated version of the toolkit for use on the latest Winsider IoT-Core builds.

Windows 10–The Week or Two that was, Mid June

The Week or Two
That Was

                          DAVID JONES  V1.1                         

Some of the issues I have been looking at over the last week or so.

Win 10 IoT: AppX Installation Options–1 (Updated)

In the previous two blogs I discussed using the Web Portal running on a Windows 10 Phone to remotely or in-phone install and Universal Windows Platform app. In this blog I discuss options for install UWP app packages on Windows 10 IoT devices. This is a work in progress as I have not had success some of these methodologies.

  • Now includes Web Device Portal UWP app running locally on IOT-Core Device.
  • AppInstall issues have now been resolved.
