TcMenu is a full feature Menu system for the arduino platform that supports many display types and remote control via an API. Drivers are available for many common displays and network interfaces. The protocol is published, and there is a Java API.
One of my hobbies is woodworking and speaker building, take a look at some of my latest attempts at building well known speaker designs. Although these are generally builds of other peoples designs, you may find some of this interesting.
We offer consultancy and development services for Java, Embedded 8 and 32 bit systems, including providing mobile and web integration to embedded products.
Audio is in our DNA, not only can we help build embedded audio devices, we are also Audiophilles that love listening to music, be it from turntable or digital source.
Our new forum allows the community to discuss the libraries (opensource and commerical) that we write.
To coin a phrase, communication between embedded devices and mobile or desktop computers "just got real". In a few short years, products being able to communicate with each other went front nice to have - to absolutely essential.

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 is ready to be triggered yet, if it is not then task manager will take your instruction on how long to wait, and then call again.
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 triggered by an external event. However, task manager will still ask your event class instance if it is ready to be triggered yet by polling, but in this case you have two choices as listed out below:
Marshalling interrupts into TaskManagerIO tasks
Interrupt handling is generally an advanced topic, but this library provides a very simple way to handle interrupts. When you tell the library to handle an interrupt, the library registers the interrupt handler on your behalf, then when the condition is met the internal handler is triggered, it sets a flag to tell the library an interrupt has been raised. The task library treats this as the highest priority, and as soon as the current task is completed the interrupt code runs.
