Consultancy and services

We offer consultancy and development services for Java, Embedded 8 and 32 bit systems, including providing mobile and web integration to embedded products.


Display technology on Arduino

For years we've had libraries and helper articles available that help using various display technology with Arduino based devices, including our very popular 7-segment driver library


Data communications

With code showing how to connect an Arduino to a PC / Mac with Java code, and examples showing how to send messages over TCP in Java, this is another informative section of the site.

Videos and youtube

We have an active youtube channel with a few videos about Arduino.

Twitter timeline

We are on github

The coders corner has a (fairly active) account on github. From Arduino libraries, Joomla to Hugo through to examples for the datacomms section, why not take a look.

Programming Arduino using tasks instead of loops - tutorial

By dave on February 9, 2018

In this tutorial for IoAbstraction’s taskManager I explain the differences between traditional loop based programming; which is very common on the Arduino platform and event based programming based on taskManager. Although event based programming looks slightly more complicated at first, as the sketch and surrounding code gets more complex, eventing will scale to that much easier. Eventing task frameworks make ongoing maintenance much easier. Example: Two LEDs blink at different rates.

Arduino Switch presses that are handled like events

By dave on February 9, 2018

Have you ever wanted to treat switch presses similar to how you work in other languages, where you get an event callback when the switch is pressed? Look no further, the IO abstraction library can do that with very little fuss. In fact it can also do the same for rotary encoders as well, treating them similar to how scroll bars work in desktop applications. To start we need to get the IoAbstraction library and open the encoderSwitch example.

Consider using Arduino for your new product

By dave on January 10, 2018

There is a common misconception in the electronics industry that Arduino is unsuited for professional development. As a result many companies try to use different, far more complex tool chains to develop software with far fewer ready made libraries available. In some cases, as unbelievable as it sounds, I’ve heard of consultants suggesting that the code is written in assembler, when the code is not even that time critical. That comes with staggering costs.

Liquid Crystal fork example using IO Abstraction library - examples

By dave on November 30, 2017

Recently, I have made a fork of Arduino LiquidCrystal (HD44780 display driver library) that allows the library to work with the IO abstraction library, meaning you can configure a display to use Arduino pins, an i2c 8574 IO expander or shift registers by simply changing one line of code in your sketch. There are two additional examples provided with this version that show how to use the fork with both a shift register and an 8574 i2c IO expander.
