Creating interrupt and threaded events with TaskManager
In this guide we assume that you are familiar with the API for scheduling tasks on task manager. Let's first discuss what we consider an event to be, and what it means to be an interrupt or threaded event. Interrupt or threaded events are subject to external actors (such as threads or interrupts). In this case the event will invariably be...
How to create a polled event with TaskManager
In this guide we assume that you are familiar with the API for scheduling tasks on task manager. Let's first discuss what we consider an event to be, and what it means to be a polled event. By polling we mean no external actors (such as threads or interrupts) are involved. Task manager will ask your event instance frequently if it...
LiquidCystalIO with a DfRobot shield
DfRobot provides the simplest way to get started with LiquidCrystalIO on Uno and Mega (and other compatible boards). It has a display with an array of switches connected to A0 (up, down, left, right and select). This library works correctly with the display and even has a shorthand way of creating the LCD for this case. Connections to an Arduino Uno,...
IoAbstraction Analog Core documentation
IoAbstraction has a simple interface to the analog capabilities of all supported boards. It provides frequently used functionality around acquiring and setting analog values from ADC, PWM and DACs. Having the ability to read and write analog values as float, where the value is between 0 and 1; where 0 is off and 1 is fully on. this capability allows you...
IoAbstraction: Arduino Pins, IO Expanders, Shift Registers using same code
Using IoAbstraction you can write a sketch / program that uses Arduino pins, shift registers and IO expander devices at the same time, very much like you'd normally use Arduino pins. This library also provides simple interrupt handling that again is consistent across Arduino, mbed and IO expander ICs. What do we mean by consistent, we mean that configuring a pin,...
Scheduling tasks with Task Manager on Arduino and mbed
Using TaskManager in your sketches TaskManager is a very simple co-operative coroutines / executor framework that allows work to be scheduled in an internal queue. Instead of writing code using delays, one simply adds jobs to be done at some point in the future. In addition to this, interrupt handling is also supported, such that the interrupt is "marshalled" and handled...
Troubleshooting and mock objects for testing
Troubleshooting IO issues using LoggingIoAbstraction Within the MockIoAbstraction.h header there is an implementation of BasicIoAbstraction that delegates through a logging layer. If you are having difficulty determining what your code is sending and receiving, this could be useful. You simply introduce the logging abstraction between your regular abstraction and the device you're having trouble with. For example: Mock objects for use...
TcMenu - Overview and quick start
Menu library and designer for Arduino and mbed TcMenu is a modular, IoT ready multi-level menu library for Arduino and mbed supporting many input, display and IoT / remote interfaces. It makes presenting configuration, status and operational information much easier. First, you design your menu structure using the designer UI, then using the code generator you convert your menu structure into...
Multi language locale based menu for Arduino and mbed
tcMenu supports compile-time internationalisation using Java-style resource bundles . You define translated strings in an directory, refer to those strings from your menu definition or C++ code, and the code generator creates C++ headers for the selected language. We enable the support by adding an directory within the project that has at least a properties file named within...
Embedded Java for Raspberry PI and other embedded Linux
Embedded Java for Raspberry PI and Linux works slightly differently to the C++ project creator in that it is a starter project with a webserver and JavaFX UI built in. After project creation you then go about configuring the project how you like, and the designer will keep the menu callbacks up-to-date in the controller, the menu definitions that make up...
