Accelerated firmware development for Linear Technology ICs on Arduino

December 06, 2013 // By Graham Prophet
Linear Technology's Linduino One development tool is 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 analogue-to-digital converters (ADCs), digital-to-analogue 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 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 can be purchased as a DC2026A-kit, in combination with the DC934A, LTC2607 dual 16-bit I²C DAC and LTC2422 20-bit SPI ADC demonstration board. These demo kits can be purchased via Linear Technology’s website or via Digi-Key, Newark, Farnell or Element14 distributors. Pricing begins at $75.00 each for the DC2026A and $125.00 each for the DC2026A kit.
