Example Code

The following examples are written in MS Visual Basic V3 for Windows using the serial communications control (MSCOMM.VBX). It can be used as a guide in implementing iPort/AFM interface programs in other programming languages and operating environments.

Note: This example code is available online at: http://www.mcc-us.com/202ug.htm#ExampleCode.

iPort/AFM Reset
Comm1.Output = Chr$(18)	'Ctrl/R
Comm1.Output = Chr$(18)	'Ctrl/R
Comm1.Output = Chr$(18)	'Ctrl/R
iPort/AFM Initialization
Comm1.Output = "/f0"	'Set iPort/AFM XON/XOFF Flow Control
Comm1.Output = Chr$(13)
Comm1.Output = "/i70"	'Set iPort/AFM’s Own Slave Address
Comm1.Output = Chr$(13)
Comm1.Output = "/d4e"	'Set Destination Slave Address
Comm1.Output = Chr$(13)
Comm1.Output = "/o"	'Open I2C Connection
Comm1.Output = Chr$(13)
Master Transmit Message
Comm1.Output = "/T~00~01"	'Send Master Tx Command
Comm1.Output = Chr$(13)	'Terminate Command
Master Receive Message
Comm1.Output = "/R10"	'Send Master Rx Command
Comm1.Output = Chr$(13)	'Terminate Command
