Linear – Arduino-compatible platform for developing and distributing firmware libraries and code

Dec 4 2013 - Design & Manufacture [More Design & Manufacture Articles]

Linear Technology has introduced the Linduino One development tool, an Arduino-compatible platform for developing and distributing firmware libraries and code for Linear Technology’s SPI and I²C-compatible integrated circuits. The Linduino One board interfaces to more than 300 QuikEval demonstration cards, supporting a variety of product types including analog-to-digital converters (ADCs), digital-to-analog converters (DACs), power monitors, intelligent Hot Swap™ controllers, temperature sensors, LED drivers, and battery management systems.

Firmware libraries for individual devices are written in C and designed to be portable to a wide variety of processors and microcontrollers. Each library has a demonstration program that can be uploaded to the Linduino One platform to allow the circuit and software to be quickly and easily verified. The free and open-source Arduino integrated development environment (IDE) compiles and loads the code into the Linduino One platform, with no additional programming hardware required.

The Linduino One tool is galvanically isolated from the host PC by an LTM2884 USB transceiver with isolated power. This provides an added measure of safety in high voltage applications such as telecom power monitoring and battery monitoring, and breaks ground loops in precision, low-noise ADC and DAC applications.

The DC2026A Linduino One board is available as a stand-alone product or as a DC2026A-kit, in combination with the DC934A, LTC2607 dual 16-bit I²C DAC and LTC2422 20-bit SPI ADC demonstration board.
