Prometheus/Athena Digital Output 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 output driver block for a given port, that port is configured for output.
I/O Module Input
Block Output Data Type
TTL low = 0.0
TTL high = 1.0
Enter a vector of numbers between 1 and 8 to select the digital output lines used from this port. This driver allows the selection of individual digital output lines in arbitrary order. The number of elements defines the number of digital lines used. For example, to use all of the digital outputs 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.
The reset vector controls the behavior of the channel at model
termination. Enter a scalar or a vector that is the same length as
the channel vector. If you specify a scalar value, that setting is
replicated over the channel vector. If you specify a value of
the corresponding channel is reset to the value specified in the initial
value vector. If you specify a value of
channel remains at the last value attained while the model was running.
The initial value vector contains the initial voltage values for the output channels. Enter a scalar or a vector that is the same length as the channel vector. If you specify a scalar value, that value is replicated as the initial value over the channel vector. The channels are set to the initial values between the time the model is downloaded and the time it is started.
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
