Prometheus/Athena Digital Input block
Simulink® Real-Time™ Library for Diamond
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.

TTL low = 0.0
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 arbitrary 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
Number the lines starting with 1 even if this board manufacturer starts numbering them with 0.
From the list, choose A, B, or C to choose one of the three I/O ports.
Enter the base sample time or a multiple of the base sample
-1 means sample time is inherited).
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
