Arduino library to interface with Broadcom/Avago HCMS-39xx and HCMS-29xx series LED displays.

The QuarkTS port for C++. An open-source OS for embedded applications that supports prioritized cooperative scheduling, time control, inter-task communications primitives, hierarchical state machines and CoRoutines.

Software I2C interface library for Arduino. Does not use any platform-specific code, and has a much simpler API than standard Wire library.

Outdoor wireless weather sensor based on TI MSP-EXP430G2 LaunchPad, SENSORHUB BoosterPack and CC110L BoosterPack. Optimized for low-power operation, 2xAA cells should be able to power the device for well over a year.

This library interfaces with the Texas Instruments BQ27441 Battery Fuel Gauge using software I2C. This allows the device to be connected to any two available I/O pins instead of the hardware-specific I2C peripheral pins.

Wireless temperature sensor which uses an MSP-EXP430FR4133 or MSP-EXPFR6989 LaunchPad, 430BOOST-CC110L wireless transceiver, and BOOSTXL-BATTPACK LiPo power source,.

Sketch for MSP430-based repeater hub for an outdoor weather sensor using a CC110L BoosterPack. Listens on one channel and repeats packet on another channel.

Library to interface with TMP007, OPT3001, and BME280 sensors using Software I2C.

MSP430-based low-power wireless temperature sensor using waterproof DS18B20 module. Demonstrates use of OneWire protocol and low-power wireless operation.

MSP430-based wireless signal tester using CC110L BoosterPack.

Wireless temperature sensor which uses an MSP-EXP430FR2433 LaunchPad, 430BOOST-CC110L wireless transceiver, BOOSTXL-BATTPACK LiPo power source, and 430BOOST-SHARP96 low-power display.

Sketch to take voltage measurements at regular intervals and store the data in non-volatile internal FRAM.

Simple retro calculator using NSA1166 bubble LED display.
