本软件是通过计算机并口控制I2C器件的程序

Welcome to use my software:
              
              "PC Based I2c Tester"

  This software will help you to archieve I2c I/O operation by PC's parallel port.

  Most world famous manufacturers use PC based stations to test their intelligent products(Mobile phone,PDA...);
  During products testing,digital I/O operations (such as Antenna&&Coupler switch,Relay controls...) are necessary;
  About PC based digital I/O,people can use integrated I/O modules such as Advantech's Digital I/O card,Keithley's 488 based 7001 switch module.  
  But,here, our idea is using a PC Based I2c protocol to archieve digital I/O.
  In the software,Three signals of PC's parallel port act as I2c's SCL and SDA(in/out) lines.
  With the support of corresponding voltage convertion circuit,my software worked safe and reliable on product testing lines.

        I hope my job will do you a favor while debugging your test stations.

                                                           Best Regards!!
