DIP Switch
Connect signals attached to DIP switches on hardware board
- Library:
SoC Blockset / Hardware Logic I/O
Description
The DIP Switch block controls the hardware logic. The hardware logic signals connected to a DIP Switch block are equivalent to the signals connected to the dual inline package (DIP) switches on the hardware board.
Ports
Input
DSInx — Input signal
Boolean scalar
xInput signal to control the hardware logic. Using this port, you can dynamically
control the hardware logic during simulation at run time. Each DIP switch has a port,
named DSIn1 to
DSInx, where
x is Number of DIP switches.
Dependencies
To enable this port, set the Specify DIP switches via
parameter to InputPort.
Data Types: Boolean
Output
DSx — Output signal
Boolean scalar
xOutput signal that returns the state of the switch. Each DIP switch has a port,
named DS1 to DSx,
where x is Number of DIP
switches.
Data Types: Boolean
Parameters
Hardware board — View selected hardware
None (default) | Supported Xilinx® or Intel ® boards | Custom boards
This parameter is read-only. To choose a hardware board and configure board parameters, see Hardware Implementation Pane.
View DIP switches location — View DIP switches
button
To view a diagram with the location of the DIP switches on the selected hardware board, click the View DIP switches location button.
This button is enabled only when you select specific Xilinx or Intel boards. For more information about these boards, refer to Supported Third-Party Tools and Hardware.
IO logic — IO logic indicator
None (default) | Active High | Active Low
This parameter is read-only. Indicates the IO logic level on the selected hardware board.
When the IO logic parameter is shown as Active
Low, the DIP Switch block accepts and outputs active low
signals when you set the Specify DIP switches via parameter to
InputPort and outputs active low signals when you set the
Specify DIP switches via parameter to
Dialog. The block represents these port names prefixed with
letter n. For example, nDS1.
Specify DIP switches via — DIP switch source
Dialog (default) | InputPort
To control the hardware logic by using the block parameters, select
Dialog. To control the hardware logic from the input port,
select InputPort.
Number of DIP switches — DIP switch selection
1 (default) | list of integers in the range [1, n]
To specify the required number of DIP switch ports, select a value from the
Number of DIP switches list. n
represents the number of available DIP switches on the specified hardware board. For
example, if you select 3 from the list, the block shows three
DIP switch ports.
To use only the nth DIP switch, set the Number
of DIP switches parameter to n and terminate the
unused DIP switch ports.
DSn — Selected DIP switches
Off (default) | On
nTo enable the nth DIP switch port, select
On for the DSn parameter.
n represents the number of available DIP switches on the
specified hardware board.
Dependencies
To enable this parameter, set the Specify push buttons via
parameter to Dialog.
Sample time — System sample time
-1 (default) | positive scalar
Specify the time interval a DIP switch toggles between On and
Off.
