基于USB接口的数据采集模块的设计与实现Design and Implementation of USB-Based Data Acquisition Module路 永 伸(天津科技大学电子信息与自动化学院，天津300222)摘要文中给出基于USB接口的数据采集模块的设计与实现。硬件设计采用以Adpc831与PDIUSBDI2为主的器件进行硬件设计，采用Windriver开发USB驱动，并用Visual C十十6.0对主机软件中硬件接口操作部分进行动态链接库封装。关键词USB 数据采集Adpc831 PDNSBDI2 Windriver动态链接库Abstract T hed esigna ndim plementaitono fU SB-BasedD ataA cquisiitonM oduleis g iven.Th ec hips oluitonm ainlyw ithA dpc831a ndP DTUSBD12i sused for hardware design. The USB drive is developed场Wmdriver, and the operation on the hardware interface is packaged into Dynamic Link Libraries场Visual C++6.0. Keywords USB DataA cquisition Adttc831 PDfUSBD12 Windriver0 引言US B总 线 是新一代接口总线，最初推出的目的是为了统一取代PC机的各类外设接口，迄今经历了1.0,1.1与2.0版本3个标准。在国内基于USB总线的相关设计与开发也得到了快速的发展，很多设计者从各自的应用领域，用不同方案设计出了相应的装置[1,2]。数据采集是工业控制中一个普遍而重要的环节，因此开发基于USB接口的数据采集模块具有很强的现实应用意义。虽然 US B总线标准已经发展到2.0版本，但由于工业控制现场干扰信号的情况比较复杂，高速数据传输的可靠性不容易被保证，并且很多场合对数据采集的实时性要求并不高，开发2.0标准产品的成本又较1.1标准产品高，所以笔者认为，在工业控制领域，目前开发基于USB总线1.1标准实现的数据采集模块的实用意义大于相应2.0标准模块。

This is the source for a C compiler that generates 386 or m68K code. Code generation is fairly good although the optimizer is a little naive... the code itself should be highly portable although there are some issues involved with porting from MSDOS that have to be resolved for example the size of LONG on unix machines is so big some of the code generated gets messed up. Code generation requires TASM to assemble the compiler output you can use the borland TLINK to produce executables, or the Watcom WLINK can also be used. PMODE systems written by TRAN are used for the DPMI interface.

This document is a "practical guide" to very quickly setup CVS/RCS source code control system. This document has custom shell scripts which are wrappers on top of CVS. These scripts provide an easy user interface for CVS. Several shell scripts are provided to make RCS more easy to use. The information in this document applies to Linux and as well as to all other flavors of Unix liks Solaris, HPUX, AIX, SCO, Sinix, BSD, SCO, etc.. and BeOS.

This example program is the source code for the FT232BM Test Application from our Utilities page. It can be used to test the handshaking lines on FT232BM based RS232/RS485/RS422 designs. This program can also be used for programming the external EEPROM over USB in a manufacturing environment. The test features require the test cable shown on ST_232_245.pdf to be connected. Our D2XX direct drivers should be installed for this application. The code can be modified to fit your requirements. To download the application source code , click here.
