Library

Simulink® Real-Time™ Library of Drivers No Longer Recommended for Use

Note

Each chip port of the Garnet-MM board can be configured independently for either input or output. Use a separate driver block for each port. Select the digital output driver block for a given port to configure the port for output.

Block Parameters

Channel vector

Enter numbers between 1 and 8 to select the digital input lines used with this port. This driver allows the selection of individual digital input lines in arbitrary order. The number of elements defines the number of digital lines used.

For example, to use all the digital inputs for the current port, enter

[1,2,3,4,5,6,7,8]

Number the lines beginning with 1 even if this board manufacturer starts numbering the lines with 0.

Port

From the list choose A, B, or C.

Chip

From the list choose 1 or 2. Note, only select 1 for the 24 line version of the Garnet-MM board. Selecting 2 for the 24 line board does nothing. You can select either 1 or 2 for the 48 line version of the board.

Sample time

Enter the base sample time or a multiple of the base sample time (-1 means sample time is inherited).

Base address

Enter the base address of the board. This entry must correspond to the DIP switch setting on the board. For example, if the DIP switch setting is 300 (hexadecimal), enter 0x300.
