GSS ADDS I2C INTERFACE TO ITS LOW POWER CO2 SENSOR

GSS ADDS I2C INTERFACE TO ITS LOW POWER CO2 SENSOR

The Internet of Things (IoT) is creating many new exciting application opportunities to create smart environments where sensors monitor for changes so that the appropriate actions can be taken. The fastest growing examples of this are HVAC (Heating Ventilation and Air Conditioning), IAQ (Indoor Air Quality), smart homes and smart offices where a network of sensors monitors temperature and

USB MIDI interface

USB MIDI interface

The RPC is a MIDI controller and implements the age-old 1980s serial MIDI bus, and the Protosynth must be capable of interfacing with it. But in general use a USB device port is much more practical than the three ubiquitous MIDI ports; it allows connecting the synth directly to a laptop or other computer at

A Raspberry Pi Interface Board

A Raspberry Pi Interface Board

The Raspberry Pi computer is eminently suitable for interfacing. It has 17 GPIO lines which can be programmed to be either inputs or outputs as well as various other functions. They are very low power lines however, and on their own can only drive tiny LEDs. With this in mind, I have designed the  interface on

Interface LED with Raspberry Pi

Interface LED with Raspberry Pi

Solution Connect an LED (see “Opto-Electronics”) to one of the GPIO pins using a 470Ω or 1kΩ series resistor (see “Resistors and Capacitors”) to limit the current. To make this recipe, you will need: Breadboard and jumper wires (see “Prototyping Equipment”) 1kΩ resistor (see “Resistors and Capacitors”) LED (see “Opto-Electronics”) Figure  shows how you can wire

Global Unichip delivers ASIC with 2GHz DDR2 3 interface on 40nm LP process

Global Unichip delivers ASIC with 2GHz DDR2/3 interface on 40nm LP process

Global Unichip, TSMC’s design arm, is manufacturing a consumer electronic applications processor ASIC with a DDR2/3 interface delivering 2.0GHz Mbps from its 40nm low power (LP) process. Key steps were designing to the performance sweet spot of GUC’s DDR2/3 high speed interface IP, a condensed package substrate, and a PCB through a precise DDR system
