Software

Within software development we can point out drivers, network programming, user interfaces (GUI) and technical solutions as industrial vision and communication applications. Real-time demands are common in our projects.

At NOW we develop software for demanding applications such as image processing, video distribution, signal processing, motor control, communication, measurement and calibration.

The applications we work with often demand high reliability and response time, something we can meet thanks to our working methods, technical expertise and modern equipment.

Throughout our 30 years in business we have been part of many different projects and have built a broad and solid experience. We are constantly updating our knowledge of new technologies and we always work with improvement of our methods.

We offer personnel with expertise in C, C++, C#, VHDL, embedded systems, GUI-development, LabView and Matlab, to mention a few.

    Test of safety critical software

    NOW’s vision platform AVT is used for recursive tests of safety critical software.

    During the development of the software, new functions are added, and bugs are corrected. At every new release, all parts of the software must be retested to see that the functions haven’t been altered in a unwanted fashion. This is a time consuming work if a tester must watch a display to check the functions visually. NOW has developed functions to make this automatically with use of a vision system, which has resulted in lower costs, higher quality, and a more content personnel.

    General I/O board

    A small and compact general I/O board with outputs for power, analogue I/O:s for 0-20 mA or 0-28 V, digital I/O:s that withstand 28 V, CAN and IO-Link, halfbridges with up to 2.6 A current drive capacity, general serial I/O:s, and differential inputs. The board is powered with 9-28 V, and an ARM based microcontroller handles the data. The board is manufactured in large quantities, so one of the challenges was to reduce the manufacturing cost.

    RFID communication board

    NOW has developed an RFID communication board, together with antennas. The board reads both half and full duplex RFID tags. A carrier wave from a TX antenna activates the RFID tag who answers with an ID, and this answer is received by an RX antenna. Analogue filters filter the signal from the tag, and the filtered data is A/D converted in an ARM processor with digital filters. The decoded ID is then sent to the host computer. The advanced analogue and digital filters givs a reading range of 1-1.5 feet, to compare with the more normal a 2-3 inches for commercial systems.

    Inspection of automatic lathing

    In lathing defects may occur caused by a worn or damaged lathe steel. NOW has developed a vision system for automatic inspection of automatic lathing with high precision. Data is stored in a data base for traceability. The system can be built-in in the lathe, or mounted in a separate inspection cell.

    Small interface-board for noisy environments

    A small interface-board for noisy environments has been developed. It has an RS485 interface where you can control termination and bias resistors. It also has a mode for BPS (Bits-Per-Second) signalling for a very low signalling rate of critical messages in a noisy environment.

    The RS485 wires may be used for for supplying power to external devices, and the board can vary the voltage and sense the power used. Thanks to these options the board can also interface a wide range of (analogue) sensors.

    Chemical industry

    NOW was contacted by a firm who had problems with one or their products, a measuring device in the chemical industry. NOW went through the designs of the different curcuit boards in the unit, and introduced changes to a number of them. New PCBs were produced, and the serial production could continue. NOW also took over, and made changes in, both the microcontroller code and the PC software in the unit.
