Abstract: This application note explains the hardware of different types of 1-Wire® interfaces and software examples adapted to this hardware with a focus on serial ports. Depending on the types of iButtons required for a project and the type of computer to be used, the most economical interface is easily found. The hardware examples shown are basically two different types: 5V general interface and 12V RS-232 interface. Within the 5V group a common printed circuit board could be used for all circuits described. The variations can be achieved by different populations of components. The same principal is used for the 12V RS-232 interface. The population determines if it is a Read all or a Read/Write all type of interface. There are other possible circuit implementations to create a 1-Wire interface. The circuits described in this application note cover many different configurations. For a custom application, one of the described options can be adapted to meet individual needs.

設計一種應用于某全地形ATV車載武器裝置中的中控系統，該系統設計是以TMS320F2812型DSP為核心，采用模塊化設計思想，對其硬件部分進行系統設計，能夠完成對武器裝置高低、回轉方向的運動控制，實現靜止或行進狀態中對目標物的測距，自動瞄準以及按既定發射模式發射彈丸和各項安全性能檢測等功能。通過編制相應的軟件，對其進行系統調試，驗證了該設計運行穩定。 Abstract: A central control system applied to an ATV vehicle weapons is designed. The system design is based on TMS320F2812 DSP as the core， uses modular design for its hardware parts. The central control system can complete the motion control of the level of weapons and equipment， rotation direction， to achieve a state of static or moving objects on the target ranging， auto-targeting and according to the established target and the projectile and the launch of the security performance testing and other functions. Through the development of appropriate software and to carry out system testing to verify the stability of this design and operation.

In the past decade, the size and complexity of manyFPGA designs exceeds the time and resourcesavailable to most design teams, making the use andreuse of Intellectual Property (IP) imperative.However, integrating numerous IP blocks acquiredfrom both internal and external sources can be adaunting challenge that often extends, rather thanshortens, design time. As today's designs integrateincreasing amounts of functionality, it is vital thatdesigners have access to proven, up-to-date IP fromreliable sources.

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.

MOTION BUILDER Ver.2 是用于監控 KV-H20/H20S/H40S/H20G 的參數設定以及當前動作狀態的軟件。 在 PC 上可以設定復雜的參數，并可以在顯示畫面上監控正在運行的 KV-H20/H20S/H40S/H20G。 關于 MOTION BUILDER Ver.2 概要、功能與使用方法的詳細說明。在安裝之前，請仔細閱讀本手冊，并充分 理解。 注意 1、使用 MOTION BUILDER Ver.2 時，必須在可以使用 KV-H20/H20S/H40S/H20G 上 連接的緊急停止開關的地方使用。 通訊異常時，不接受 MOTION BUILDER Ver.2 的“強制停止”，可能會導致事故指示發生。發生通信異常時，MOTION BUILDER Ver.2 的“強制停止”按鈕將不起作用。 2、JOG 過程中，不能采用斷開 PLC 的連接電纜等手段停止通訊。 KV-H20/H20S/H40S/H20G 單元的 JOG 繼電器會一直保持 ON，機器繼續運轉，并可能導致事故發生。 3、執行監控或者寫入參數（設定）時，不能斷開和 PLC 的連接電纜。 否則會發生通訊錯誤，PC 可能會被重啟。KV-H20/H20S/H40S/H20G 內的數據可 能會損壞。 4、在 RUN 過程中，KV-1000/700 進行 JOG 示教時，必須在 PROG 模式下實施。 如果掃描時間較長，則反映的時間變長，且可能發生無法預料的動作。 5、發送到 KV-1000/700 的單元設定信息必須與當前打開的梯形圖程序的單元設定信 息一致。如果設定信息不同，則顯示錯誤，且不運行。 6、錯誤操作或者靜電等會引起數據變化或者去失，為了保護數據，請定期進行備份。 指示 關于數據的變化或者消失引起的損失，本公司不負任何責任，請諒解。 7、保存數據時，如果需要保留原來保存的數據，則選擇“重命名保存”。 如果“覆蓋保存”則會失去原來保存的數據。 運行環境及系統配置 運行 MOTION BUILDER Ver.2 ，必須具備如下環境。 請確認您使用的系統是否符合如下條件、是否備齊了必需的設備。 對應的 PC 機型 • IBM PC 以及 PC/AT 兼容機（DOS/V） 系統配置 • CPU Pentium 133 MHz 以上 支持 Windows 的打印 （推薦 Pentium 200 MHz 以上） • 內存容量擴展內存 64MB 以上 • 硬盤可用空間 20MB 以上 • CD-ROM 驅動器 • 接口 RS-232C 或者 USB

Abstract: Using a wafer-level package (WLP) can reduce the overall size and cost of your solution.However when using a WLP IC, the printed circuit board (PCB) layout can become more complex and, ifnot carefully planned, result in an unreliable design. This article presents some PCB designconsiderations and general recommendations for choosing a 0.4mm- or 0.5mm-pitch WLP for yourapplication.
