iPort Message Manager Software for Windows

Introduction to Message Manager

The MCC iPort Message Manager Software, when used in conjunction with an MCC iPort allows a PC to become an I2C Master or Slave device, transmitting or receiving I2C messages between the PC and one or more I2C devices across an I2C Bus.

The iPort Message Manager is designed to be a simple application for experimenting with I2C messages. It provides methods to:

1.Set the device’s I2C Slave address, General Call Enable, and other operating parameters.

2.Master Transmit ASCII text or Hex [~00...~FF] data to a specified I2C Slave Receiver device.

3.Master Receive data from a specified I2C Slave Transmitter device.

4.Perform Master Read after Write operation.

5.Slave Transmit data to a requesting I2C Master Receive device.

6.Display Slave Receiver data.

__

7. Assert or release the INT signal (iPort/AFM only).

Each iPort Message Manager I2C message can include up to 23 bytes of 8-bit ASCII binary data, although the iPort itself is capable of sending or receiving I2C messages up to 64K bytes in length.
