Embedded micro-controller firmware
Dedicated microcontrollers are built into most leading edge products from sophisticated environmental controllers to simple door chimes. We have implemented microcontroller solutions across a wide range of market sectors View the project example page for a more definitive list.

Designing and implementing firmware in this arena has allowed us to accumulate specialist knowledge of the capabilities of available processors and how these match the needs of particular applications. This is recognised by a number of microcontroller manufacturers for whom we are registered consultants. Click on the Microcontroller page to see a list
Our firmware is more usually written in the 'C' language useing cross-compilation for the target microcontroller. Where required specific assembler languages are used. We use a variety of tried and tested methods to ensure that the design meets the specification, taking into account the implications of interrupts and real-time operation. Simple scheduling loops and state-driven operations are often required although for larger controllers a suitable O/S may be chosenSoftware
As the universal platform of the PC has evolved, so we have taken opportunities to provide PC applications for commerce and industry. We specialise in data capture or PC based control systems often linking to embedded controllers. We place great emphasis on the man-machine interface and have particular expertise in graphical solutions. Solutions are nomally provided in VBasic an Visual C++. In addition expertise in Delphi (particularly for data solutions) and Java (for web-based solutions) can be provided
Digital and analogue electronics
Complementing our firmware design skills, we are able to offer a complete electronic design service. Products may require a mixture of both digital and analogue electronics and we can provide circuit designs covering both areas.

PCB design and layout
Computerised printed circuit board facilities, allow us to offer a competitive PCB design and layout service. AND Software will transfer a circuit design into an easy-to-read schematic form, linked by computer to the final layout to ensure correct connectivity. Changes to the circuit design transfer easily from schematic to layout, allowing simple modification at a later stage. An extensive library of component footprints, surface mount and through-hole, helps to speed-up the layout process, with new components easily added to the library when required. Autorouting is often used for rapid development of prototype circuits or to help judge component placement in more complex designs. Ground planes can be generated for improved EMC performance. The board outline, tracks and ground planes can all have complex shapes, including arcs.
AND will arrange for the manufacture of prototypes and provide
layouts on film or disk with all the necessary documentation
to support full production and maintenance.
