DIP Switch

Connect signals attached to DIP switches on hardware board

• 

Libraries:
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.

Examples

Streaming Data from Hardware to Software

A systematic approach to design the data-path between hardware logic (FPGA) and embedded processor using SoC Blockset™.

Ports

Input

DSInx — Input signal

Boolean scalar

Input 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

Output 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

To 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.
