Digital controlled Uninterruptible Power Supply

Bluewind, as a partner of Analog Devices, has designed this Software Development Kit for Uninterruptible Power Supplies based on the ADI's ADMC401 Single Chip Motion Controller. We also offer you this application note that deals with using a DSP in a UPS design.

Digital Controlled Inverter for Uninterruptible Power Supplies with Infineon Tricore TC1775 32bit processor

TriCore Three phase, on-line Uninterruptible Power Supplies require both CPU/RISC general purpose control capability and Digital Signal Processing skill. The feasibility of complete UPS control with Infineon TriCore architecture is investigated. TriCore mixes a RISC 32bit Cpu, one DSP unit and one independent Peripheral Control Processor(PCP) .

White goods application: Sensorless Brushless DC Motor Control with Infineon C164CI.

BlueWind developed this Brushless Reference Design in collaboration with Infineon Automotive and Industrial Group. The project is targeted primarily to the design and development in the white goods industry.The BLDC Application software is intended to give the customer a ready to use platform: it is conceived to be used upon an Infineon Motor Control StarterKit, useful for either Brushless, V/F Induction or Field Oriented Control software modules.

Audio: DSP filtering and equalization

This application of Digital Signal Processing is aimed at a particular target: helping all those partially deaf people who have serious problems at hearing with the telephone speaker. A better hearing has been accomplished by using filtering equalization techniques in the frequency domain. An Analog Devices 16 bit fix-point ADSP2181 Digital Signal Processor has been used to perform the first implementation and test of this equipment. Another implementation is based on a Cirrus Logic ARM7 derivative and Open Source development tools.

Audio: MP3

Bluewind developed this MP3 decoder reference design based on Cirrus Logic EP7209 ARM7 derivative. The design relies on the ARM720 ARM core, and shows a complete range of hardware and software tools used for development. Suggestions on ARM SDT and GNU toolchains are given.

Embedded TCP/IP

Bluewind developed applications where complicated communication protocols are needed in embedded environments, using 16 bits microcontrollers and dedicated Ethernet peripherals. You can find hints about using networking libraries together with a Real Time Operating System visiting our TCP/IP application notes.

Open Source ARM toolchain

Bluewind is involved in projects where ARM cores are used. This is why we looked for an ARM compiler and, more generally, for an ARM toolchain comprising not only the arm-elf compiler but also a debugger with a simple GUI. The solution we found, was building a GNU gcc cross-compiler (and other tools we needed) on a Linux host machine. You can find the details visiting the dedicated pages. This ARM toolchain (GNU) is Open Source software!

Nohau

nohau.gif (1172 byte) Nohau is a leading manufacturer of emulation systems, supporting a wide variety of different devices ranging from 8051 derivatives up to latest Infineon 16 and 32 bit microcontrollers. Bluewind currently owns Nohau emulation systems for Infineon microcontrollers and will use other Nohau tools when possible.

Industrial control

Bluewind has been contracted by the University of Padova as tutor for the Automation Laboratory training during the Electronics Engineering Diploma course, to be held in Vicenza, Italy. Students can find here the material used during the lessons: MatLab examples, Keil uVision projects, and hardware descriptions.
