This document discusses interfacing the Stellaris LM3S811 microcontroller with the DAC5571 digital-to-analog converter over I2C. It provides an overview of the Stellaris I2C interface and how to establish communication with the DAC5571. Code examples are given to generate waveforms from the DAC5571 controlled by the Stellaris microcontroller over I2C.
This document discusses enabling two-way communication and mesh networking capabilities for the CC2530 ZigBee Network Processor Mini Kit. It provides code examples for a wireless doorbell application that allow devices to receive messages when a button is pressed or on a timer. It also explains how to use routers to extend the communication range of the network and receive messages from devices connected to other routers.
This document describes how to interface a Stellaris LM3S811 microcontroller with a DAC7311 digital-to-analog converter using SPI communication. It provides details on the SPI configuration of the Stellaris, the pinout and connections of the DAC7311 evaluation board, and code examples to generate waveforms from the DAC output by transmitting data over SPI. Evaluation board layout diagrams and actual connection snapshots are shown.
Planning partner of Swissnex event, "Sustainability - A Global Journal Panel Discussion", at Nanyang Technological University with ERI@N and Swisspro. Guests of Honour includes Prof Bertil Andersson, NTU President-Designate and Joerg Al. Reding, Ambassador of Switzerland.
The Green and Sustainable Technologies Society (GSTS) is a student-run initiative at the Nanyang Technological University (NTU) that aims to promote green technologies. It brings together students from different disciplines to encourage and accelerate green technology and industry. GSTS hopes to fill the gap of integrating technology, business, and environmental sustainability. Its activities include presentations from research and consultation departments, sourcing projects from industry partners, and organizing conferences on topics like green job opportunities and integrating green technology into business. GSTS's future plans include registering as an official society, engaging external organizations, and becoming a leading group in educating youth on green technologies and business practices.
RecoBeE is a community platform that allows consumers to exchange real-time information about products to make more informed purchasing decisions, as advertisements alone do not provide sufficient information. It also gives merchants a way to capture consumer attention and learn more about their customers' needs through the sharing of product reviews and using vouchers. The platform connects shops, consumers, and RecoBeE through one-way and two-way communication to share and retrieve updated product information via devices like iPhone and iPod Touch.
LyRex aims to change how consumers and businesses interact through its RecoBeE mobile application and website. RecoBeE allows consumers to get recommendations and reviews from other users, search for deals, and get real-time updates. It also gives businesses the ability to target customers through i-Vouchers. LyRex sees problems in how merchants reach customers and how customers make decisions without real-time information. It aims to solve this by creating a community where users can share information and find the best deals and recommendations. Within 3 years, LyRex expects to have 58,000 customers and $1.88 million in sales with a $1.1 million profit by leveraging mobile social networking.

31. 致理綠色展場專案計畫教育訓練 致理技術學院 Chihlee Institute of Technology Resistor: 1MΩ 3.3kΩ 4.7kΩ R3, R4 = 210Ω C1 = 10uF This circuit gives alternating LED flashing, but with different flashing period between LED 1 and LED 2. The ON period of the LED 1 is proportional to the R2 value, and the ON period of the LED 2 is proportional to R1 + R2 value. If you use a 1M variable resitor in series with a 22k resitor to replace R1, then you get a variable period flasher. The power consumption will be much lower if you use only LED 1 (remove the LED 2 and R4), and choose R2 value to be much lower than R1. This would give you a strobe effect since the ON period will be much shorter than the OFF period. 實作三
