In a UDS session(diagnostic session ),aprogram application on a computer constitutes the client(within UDS, it is calledPCAN-UDSTester), the server is the ecu being tested and the diagnostic requests from client toserver are called services. The client always starts with a request and this ends with apositive or negative response from the server(ECuSince the transport protocol of UDS is done using ISo-TP, an international standardPCAN ISOTPfor sending data packets over a CAN Bus, the maximum data length that can betransmitted in a single data-block is 4095 bytes.PCAN-UDS API is an implementation of the Uds on CAN standard the physicalcommunication is carried out by PCAN-Hardware (PCAN-USB, PCAN-PCI etc )throughPCAN-Basithe pCAN-ISo-TP and PCAN-Basic API (free CAN APls from PEAK-System). Because ofthis it is necessary to have also the pCAN-1S0-tP and PCAN-Basic APls(PCAN-ISO-TP. dll and PCAN Basic. dll) present on the working computer where UdS is intended tobe used. PCAN-UDS, PCAN-ISO-TP and PCan-Basic apis are free and available for allFigure 1: Relationship of thepeople that acquire a pCAn-hardware2.2 Using PCAN-UDSSince PCAN-UDS API is built on top of the PCAN-1So-TP API and PCAN-Basic APls, it shares similar functions. Itoffers the possibility to use several PCAn-UDS (PUds) channels within the same application in an easy way. Thecommunication process is divided in 3 phases: initialization interaction and finalization of a puds-channelInitialization In order to do UDS on CAN communication using a channel, it is necessary to initialize it first. Thisis done by making a call to the function UDS_ Initialize (class- method: InitializePCAN-UDS APi- User ManualInteraction: After a successful initialization a channel is ready to communicate with the connected can bus.Further configuration is not needed the 24 functions starting with UDS Svc(class-methods: starting with Svccan be used to transmit UdS requests and the utility functions starting with Uds WaitFor(class- methodsstarting with WaitFor) are used to retrieve the results of a previous request. the Uds read and UDS Write(class-methods: Read and Write are lower level functions to read and write UDs messages from scratch. Ifdesired, extra configuration can be made to improve a communication session, like service request timeouts orISo-TP parametersFinalization: When the communication is finished, the function UDS_ Uninitialize(class-method: Uninitializeshould be called in order to release the puds-channel and the resources allocated for it. In this way thechannel is marked as free"and can be used from other applications23 FeaturesI mplementation of the UDS protocol(iSo 14229-1)for the communication with control unitsWindows DLLs for the development of 32-bit and 64-bit applicationsPhysical communication via Can using a Can interface of the pcan seriesUses the pcan-Basic programming interface to access the can hardware in the computerUses the pCAn-ISo-TP programming interface(iso 15765-2)for the transfer of data packages up to 4095bytes via the can bus2.4 System Requi rementsL- Windows 10, 8.1, 7(32/64-bitAt least 512 Mb ram and 1 GHz CPUPC CAN interface from peak-SystemPCAN-Basic APlL PCAN-SO-TP API2.5 Scope of supplyInterface DLL, examples, and header files for all common programming languagesDocumentation in pdf formatDocumentation in HTML Help formatPCAN-UDS APi- User Manual3 DLL API ReferenceThis section contains information about the data types (classes, structures, types, defines enumerations)andAPI functions which are contained in the pcan-uds api3.1 NamespacesPEAK offers the implementation of some specific programming interfaces as namespaces for the.

滤波器是一种选频装置，可以使信号中特定的频率成分通过，而极大地衰减其它频率成分。在测试装置中，利用滤波器的这种选频作用，可以滤除干扰噪声或进行频谱分析。广义地讲，任何一种信息传输的通道（媒质）都可视为是一种滤波器。因为，任何装置的响应特性都是激励频率的函数，都可用频域函数描述其传输特性。因此，构成测试系统的任何一个环节，诸如机械系统、电气网络、仪器仪表甚至连接导线等等，都将在一定频率范围内，按其频域特性，对所通过的信号进行变换与处理。本文所述内容属于模拟滤波范围。主要介绍模拟滤波器原理、种类、数学模型、主要参数、ＲＣ滤波器设计。尽管数字滤波技术已得到广泛应用，但模拟滤波在自动检测、自动控制
