QuadratureTech

QuadratureTech is an engineering practice that designs embedded software, firmware and electronics hardware. The work covers the whole path from an initial concept to a finished product, and the stated approach is hands-on and self-directed.

What QuadratureTech offers

• Embedded firmware — time-critical measurement and control code in C, C++ and assembler, written without an operating system or with a real-time one if the client prefers.
• Code maintenance — upkeep of existing code, including work inside a team using a waterfall process.
• Interfaces and drivers — LCD graphical interfaces, drivers for integrated circuits, and buses and protocols such as I2C, SPI, UART, CAN, Modbus, USB and Ethernet.
• Programmable logic — small FPGA design on Xilinx CPLD parts and system-on-chip designs on Cypress PSoC5LP.
• Desktop software — PC programs in C#, C++ .NET, Visual Basic 6 and Python, including production tools and an email server written in C#.
• Hardware design — schematics and multilayer PCB layout for control systems with character, graphic, TFT and seven-segment displays, in both analogue and digital circuits.
