Arduino Bluetooth Keypad Utilities: KeyPadKeysUWPLib

Abstracts the Keypressed event further by interpreting it in terms of the actual key press. Has a delegate for each key which can be programmatically set by the dependant app as the function (implemented in the app) to call when each each key is pressed. Concepotually, sits on top of KeypadUWPLib.

Arduino Bluetooth Keypad Utilities: Soft Keypad Test UWP App

A simple app to test the KeypadUWPLib. Implements a keypad as part of the app, which when pressed actions the keypad events. Some limitations imposed by lack of KeyUp event with XAML Buttons.

Arduino Bluetooth Keypad Utilities: UWP BluetoothSerialLib

A modularisation of the Generic Bluetooth Serial App extracting out all of the UI functionality. Received serial messages are interpreted as Phone Keypad events. Depends upon KeypadUWPLib as it fires the keypad events based upon received messages.

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
