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...
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...
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,...
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...
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,...
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...
Getting started with the web menu designer
Summary Our web-based menu designer (TcMenu Turbo) creates and maintains your embedded menu project online. This guide assumes initializer mode . In initializer mode you set up the basic menu structure, choose and configure plugins for your hardware, then run code generator. Using initializer, all plugin code and wiring will be generated into the and files. You menu structure...
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...
Using menu designer as an embedded initializer
You can choose to use tcMenu embedded menu designer as an initializer. This means that you can add new menu items without having to rebuild your project. This makes it much easier to use tcMenu. In the initializer case, the intended workflow is to create a project that works with a given display driver and input configuration and then manage the...
