Library

xPC Target Library for Diamond

Note

Onyx-MM boards have two digital I/O chips, each with three 8-bit digital I/O ports, for a total of 48 I/O lines. Each port can be configured independently for either input or output. Use a separate driver block for each port. Select the digital input driver block for a given port to configure the port for input.

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 any 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 the 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.

Sample time

Enter a base sample time or a multiple of the base sample time.

Base address
