Here are just some examples of some more or less complex solutions, while applying our strengths to real/difficult situations:

  • TESTER AT1: automotive testing product produced inside KulzerTEC, completely from the first idea, design, software development, hardware development, prototype construction, testing and production.
  • Firmware Optimization: squeezing the code size from about 3.200 Byte to about 1.900 Byte without losing any functionality, to fit inside a 2KB RAM for an ASIC containing a legacy 8bit MC6805 micro-controller with limited hardware.
  • Hardware-Near Software Development: the “TESTER AT1” needed all kinds of firmware pieces to be programmed to harness its various hardware components, such as USB, JTAG, power outputs/inputs, LCD display, keyboard, EEPROM memories, circuits/inputs/outputs switching options and even Lambda measurement/simulation circuitry with the CJ125.
  • Time-Critical Software Details: measurement of 1000 samples @100Ksamples/s from an analog sensor input, while simultaneously storing the minimum/maximum/average value with a MSP430 @8MHz without losing one single sample.
  • Complex Bug-Searching: the search for a very strange bug related to one engine misfire on each 2 hours of motorsport racing, got to a successful end after one full workweek, pointing to a misbehaving interrupt out of 64 possible sources.
  • Software Porting: porting of an original code inside an MSP430 into a legacy 8bit MC6805 and OKI micro-controllers, including all the needed driver firmware changes and adaptations due to the different target hardware circuitry.
  • Hardware Porting: the complex ECU2010 project, where the first prototyping hardware structure was fully implemented with MSP430 micro-controllers, which had to be ported to an FPGA platform, maintaining the structure and mechanisms.
  • Code Embellishment: complete overhaul of all the software modules of the first MS4.x Bosch Motosport ECU firmware, to create the newer “MS4 Sport”, greatly enhancing the general visual and functional aspects of the complete package.
  • Machine-Level Programming: various low-level functionality for the MSP430, such as ultra-fast binary division algorithms, ultra-fast @100Ksamples/s limiting and averaging, as well as ultra-fast engine-speed simulation output drivers.
  • New Micro-Controllers: harnessing the power, capabilities and early-die hardware bugs of the newest Texas Instruments C2000 micro-controller, by designing, developing and testing a new prototyping platform firmware.
  • New Ideas and Needs: since no commercial source-management software was being able to cope with the very specific and complex management needs of the MS4.x Motorsport ECU software, a new tool was developed from scratch, which is being used for almost 10 years now.
  • Chip characterisation: complete or partial characterisation of a chip’s behaviour, including datasheet production, limit-testing and even test-destruction, for sensing chips and switched power-supply chips
  • Extreme uC Limit-Programming: making an MSP430 only @10MHz to make up to 30.000RPM engine-speed “60-2” teeth crank-wheel simulation, with 8 simultaneous outputs with total configuration flexibility down to 1° of resolution and 0,08% RPM resolution @10.000RPM, by exploiting all potential hardware features (DMA, interrupts) and software optimizations.
  • Innovative/Revolutionary Solutions: design and development of a new Lambda-sensor simulation circuit with patentable analog opamp circuitry and firmware drivers to accurately simulate a wide range of Lambda and internal resistance values, therefore allowing the user to simulate Lambda values with ranges and precision never before even by far attained.
  • VBA-Driven Microsoft Office Management Tools: design, development and maintenance of various VBA tools mainly for Excel with a total of over 16.000 lines-of-code, including graphical data treatment and complex management algorithms

We are a “ALL-IN-ONE” highly synergetic services/consulting/development team, in that we are able to navigate from the lowest hardware, passing through firmware, ranging up to the desktop software levels, therefore connecting all the dots for embedded products, even down to production. So, if you need embedded software plus the corresponding hardware and the corresponding desktop GUI software, eventually even desktop test-software and organizing/managing tools in Microsoft Office with full VBA enhancements, you are at the right place! We are analysis and integration specialists, while also displaying a very high level of synergy in that problems are very often attacked in parallel with highly cooperative working processes! Do you have some “dirty work” to do and nobody wants to do it anymore? Then we are also the indicated executors, since meanwhile our work pick-up and stamina capacities are recognized by our customers. We are used to multi-locational and multi-cultural individual and team work. We are your ideal partner for your “Nearshoring” / “Near-shore Development” needs.
