The LPC2292/2294 microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 256 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 pct with minimal performance penalty. With their 144-pin package, low power consumption, various 32-bit timers, 8-channel 10-bit ADC, 2/4 (LPC2294) advanced CAN channels, PWM channels and up to nine external interrupt pins these microcontrollers are particularly suitable for automotive and industrial control applications as well as medical systems and fault-tolerant maintenance buses. The number of available fast GPIOs ranges from 76 (with external memory) through 112 (single-chip). With a wide range of additional serial communications interfaces, they are also suited for communication gateways and protocol converters as well as many other general-purpose applications. Remark: Throughout the data sheet, the term LPC2292/2294 will apply to devices with and without the /00 or /01 suffix. The suffixes /00 and /01 will be used to differentiate from other devices only when necessary.

The contents are: Instructor Notes.doc – this document. labviewIntroduction-SixHour.ppt – a PowerPoint presentation containing screenshots and notes on the topics covered by the course. Convert C to F (Ex1).vi – Exercise 1 solution VI. Convert C to F (Ex2).vi – Exercise 2 solution subVI. Thermometer-DAQ (Ex2).vi – Exercise 2 solution VI. Temperature Monitor (Ex3).vi – Exercise 3 solution VI. Thermometer (Ex4).vi – Exercise 4 solution subVI. Convert C to F (Ex4).vi – Exercise 4 solution subVI. Temperature Logger (Ex4).vi – Exercise 4 solution VI. Multiplot Graph (Ex5).vi – Exercise 5 solution VI. Square Root (Ex6).vi – Exercise 6 solution VI. State Machine 1 (Ex7).vi – Exercise 7 solution VI. The slides can be presented in two three hour labs, or six one hour lectures. Depending on the time and resources available in class, you can choose whether to assign the exercises as homework or to be done in class. If you decide to assign the exercises in class, it is best to assign them in order with the presentation. This way the students can create VI’s while the relevant information is still fresh. The notes associated with the exercise slide should be sufficient to guide the students to a solution. The solution files included are one possible solution, but by no means the only solution.

The main objective of this book is to present all the relevant informationrequired for RF and micro-wave power amplifier design includingwell-known and novel theoretical approaches and practical design techniquesas well as to suggest optimum design approaches effectively combininganalytical calculations and computer-aided design. This bookcan also be very useful for lecturing to promote the analytical way ofthinking with practical verification by making a bridge between theoryand practice of RF and microwave engineering. As it often happens, anew result is the well-forgotten old one. Therefore, the demonstrationof not only new results based on new technologies or circuit schematicsis given, but some sufficiently old ideas or approaches are also introduced,that could be very useful in modern practice or could contributeto appearance of new ideas or schematic techniques.

在研究傳統家用燃氣報警器的基礎上，以ZigBee協議為平臺，構建mesh網狀網絡實現網絡化的智能語音報警系統。由于傳感器本身的溫度和實際環境溫度的影響，傳感器標定后采用軟件補償方法。為了減少系統費用，前端節點采用半功能節點設備，路由器和協調器采用全功能節點設備，構建mesh網絡所形成的家庭內部報警系統，通過通用的電話接口連接到外部的公用電話網絡，啟動語音模塊進行報警。實驗結果表明，在2.4 GHz頻率下傳輸，有墻等障礙物的情況下，節點的傳輸距離大約為35 m，能夠滿足家庭需要，且系統工作穩定，但在功耗方面仍需進一步改善。 Abstract: On the basis of studying traditional household gas alarm system, this paper proposed the platform for the ZigBee protocol，and constructed mesh network to achieve network-based intelligent voice alarm system. Because of the sensor temperature and the actual environment temperature, this system design used software compensation after calibrating sensor. In order to reduce system cost, semi-functional node devices were used as front-end node, however, full-function devices were used as routers and coordinator，constructed alarm system within the family by building mesh network，connected to the external public telephone network through the common telephone interface, started the voice alarm module. The results indicate that nodes transmit about 35m in the distance in case of walls and other obstacles by 2.4GHz frequency transmission, this is able to meet family needs and work steadily, but still needs further improvement in power consumption.

為滿足無線網絡技術具有低功耗、節點體積小、網絡容量大、網絡傳輸可靠等技術要求，設計了一種以MSP430單片機和CC2420射頻收發器組成的無線傳感節點。通過分析其節點組成，提出了ZigBee技術中的幾種網絡拓撲形式，并研究了ZigBee路由算法。針對不同的傳輸要求形式選用不同的網絡拓撲形式可以盡大可能地減少系統成本。同時針對不同網絡選用正確的ZigBee路由算法有效地減少了網絡能量消耗，提高了系統的可靠性。應用試驗表明，采用ZigBee方式通信可以提高傳輸速率且覆蓋范圍大，與傳統的有線通信方式相比可以節約40%左右的成本。 Abstract: To improve the proposed technical requirements such as low-ower， small nodes， large capacity and reliable network transmission， wireless sensor nodes based on MSP430 MCU and CC2420 RF transceiver were designed. This paper provided network topology of ZigBee technology by analysing the component of the nodes and researched ZigBee routing algorithm. Aiming at different requirements of transmission mode to choose the different network topologies form can most likely reduce the system cost. And aiming at different network to choose the correct ZigBee routing algorithm can effectively reduced the network energy consumption and improved the reliability of the system. Results show that the communication which used ZigBee mode can improve the transmission rate， cover more area and reduce 40% cost compared with traditional wired communications mode.

針對UHF讀寫器設計中，在符合EPC Gen2標準的情況下，對標簽返回的高速數據進行正確解碼以達到正確讀取標簽的要求，提出了一種新的在ARM平臺下采用邊沿捕獲統計定時器數判斷數據的方法，并對FM0編碼進行解碼。與傳統的使用定時器定時采樣高低電平的FM0解碼方法相比，該解碼方法可以減少定時器定時誤差累積的影響；可以將捕獲定時器數中斷與數據判斷解碼相對分隔開，使得中斷對解碼影響很小，實現捕獲與解碼的同步。通過實驗表明，這種方法提高了解碼的效率，在160 Kb/s的接收速度下，讀取一張標簽的時間約為30次/s。 Abstract: Aiming at the requirement of receiving correctly decoded data from the tag under high-speed communication which complied with EPC Gen2 standard in the design of UHF interrogator， the article introduced a new technology for FM0 decoding which counted the timer counter to judge data by using the edge interval of signal capture based on the ARM7 platform. Compared with the traditional FM0 decoding method which used the timer timed to sample the high and low level， the method could reduce the accumulation of timing error and could relatively separate capture timer interrupt and the data judgment for decoding， so that the disruption effect on the decoding was small and realizd synchronization of capture and decoding. Testing result shows that the method improves the efficiency of decoding， at 160 Kb/s receiving speed， the time of the interrogator to read a tag is about 30 times/s.
