Diamond Prometheus/Athena/Athena II Digital Input - Prometheus/Athena Digital Input block

Library

xPC Target Library for Diamond

Note

Prometheus and Athena boards have three I/O ports, each containing eight digital I/O lines. You can independently configure these ports for either input or output. Use a separate driver block for each port. By selecting the digital input driver block for a given port, that port is configured for input.

Scaling Input to Output

Hardware Input	Block Output Data Type	Scaling
TTL	Double	TTL low = 0.0 TTL high = 1.0

Block Parameters

Channel Vector

Enter a vector of numbers between 1 and 8 to select the digital input lines used from 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 of the digital inputs for the current port, enter

[1:8]

Number the lines starting with 1 even if the board manufacturer starts numbering them with 0.

Port

From the list, choose A, B, or C to choose one of the three I/O ports.

Sample time

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

Base address

Enter the base address of the board. It is important that this entry corresponds to the DIP switch settings on the board. For example, if the base address is 280 (hexadecimal), enter

0x280
