Electronics design and embedded software development services

Areas of expertise

Infado has multi-year experience in design and development of advanced, complex audio systems, intelligent home systems and multi-layer cable and radio communication architectures. The key areas of expertise include:

• Control systems on ARM i DSP microcontrollers
• Communication systems using cable (UART, I2C, SPI), radio and network (LAN/WAN) interface protocols
• Hjgh-throughput, real-time cable and radio transmission using TCP/IP, UDP, SPI, SPDIF, I2S
• DSP filtering and processing, including high-bandwidth signal processing
• Radio control 2,4 GHz systems
• Precise, low-jitter clock generation, DDS synthesis and digital PLL
• Power control solutions, e.g. precise synchronous PWM converters – step-down, buck-boost, SMPS
• Control and communication systems using standalone Linux modules
• Industrial control systems algorithms – e.g. PID regulators
• PC and mobile applications (front-end/GUI)

 Key features of our project approach

• First-class competence and experience in electronics and software projects implementation in various industries and technologies
• Professional and efficient project management

1. Each project starts with requirements summary prepared by Infado as a common starting ground
2. Larger-scale projects are monitored for meeting deadlines and quality assurance objectives by a project manager with long-standing experience in IT and business project management, also international
3. Best practice project management that brings actual total project costs optimization

• Full-scope, “turn-key” electronics and software project implementation including also the mechanical design if required (e.g. enclosure)
• Capability to develop complex embedded software algorithms –e.g.       advanced DSP algorithms, on-line, high-bandwidth data transmission (10 Mbit/s real-time), multi-layer cable, radio or mixed communication architectures

An important distinguishing competence of Infado is strong experience in functional and technical specifications of extensive embedded systems using best practices in IT systems documentation. It results in minimisation of the biggest risk in IT projects implementation – i.e. misunderstandings of requirements and design specifications between the client and the integrator.

Selected electronic modules implementations

The modules listed below are flexible electronic designs with rich peripherals and highly configurable base software that can allow for a fast-track product design resulting in reduced project cost and timeline:

• Advanced 40-bit floating point DSP processing module, well suited to e.g. IIR/FIR filtering
• Wireless 2,4 MHz module with 5 Mbit/s real-time transmission bandwidth
• Control board with 7x 230V power outputs with intelligent on/off algorithms based on environment sensor data and individual line power consumption measurement
• Sensor module capable of high-precision lighting (two-range for exterior and interior) and temperature measurements and smoke detection. The module is powered with photovoltaic power supply circuit
• Low jitter clock generation module with configurable frequencies up to 500MHz using DDS synthesis
• High-power step-down DC voltage regulator with very high precision (less than 0,01%) and dynamic range (min. value less than 0,05% of supply voltage)
• Advanced, innovative, digital class D high resolution power amplifier rated at 4x200W with advanced control and monitoring implemented on an ARM microcontroller
• Low-power LCD 3,2 inch display with a GUI menu application
