Modelica_DeviceDrivers.Blocks.Examples.TestSerialPackager

Information

The example demonstrates that pack and unpack blocks of the SerialPackager package can be connected directly.

Modelica_DeviceDrivers.Blocks.Examples.TestSerialPackager_String

Information

Using Strings in input or output connectors is not very common in Modelica. There are currently no standard connectors for Strings available in the MSL. Nevertheless, the SerialPackager package provides blocks for Strings, too. The use of this blocks is demonstrated in this example.

Please note: The model should work with Dymola 2014, but seems not with Dymola 2013 FD01 (and probably previous versions).

Modelica_DeviceDrivers.Blocks.Examples.TestSerialPackager_UDP

Information

The uDPSend block sends to the local port 10002. The uDPReceive block starts a background process that listens at port 10002. Consequently, the uDPReceive block receives what the uDPSend block sends.

Note: There is no causality between the uDPSend block and the uDPReceive block. Therefore the execution order of the blocks is not determined. Additionally, the uDPReceive block starts an own receiving thread, so that the time the data was received is not equal to the time the external function within the uDPReceive block was called. This indeterminism may also show up in the plots.

Modelica_DeviceDrivers.Blocks.Examples.TestSerialPackagerBitPack_UDP

Information

In particular this model demonstrates how integer values can be packed and unpacked at bit level using the PackUnsignedInteger and UnpackUnsignedInteger blocks.

Modelica_DeviceDrivers.Blocks.Examples.TestSerialPackager_SharedMemory

Information

The sharedMemoryWrite block writes to the memory partition with memoryID = "sharedMemory". The sharedMemoryRead block reads from that partition.

Note: There is no causality between the sharedMemoryWrite block and the sharedMemoryRead block. Therefore the execution order of the blocks is not determined. This indeterminism may also show up in the plots.

Modelica_DeviceDrivers.Blocks.Examples.TestSerialPackager_SoftingCAN

Information

Support for Softing CAN bus

Please, read the package information for SoftingCAN first!

The example

The example is configured for the "CANusb" interface card from Softing (www.softing.com) (but, given that the deviceName parameter is set correctly, should work with all of their interface cards supporting their Softing CAN Layer 2 software API). Two messages are defined: txMessage for sending and rxMessage for receiving. The SerialPackager blocks are used to add/retrieve data to/from the messages.

Modelica_DeviceDrivers.Blocks.Examples.TestSerialPackager_SocketCAN

Information

Example for Linux Socket CAN interface support

Will only work on Linux!

Please, read the package information for SocketCAN first!

The example

The example is configured to use the virtual CAN interface "vcan0". The SocketCAN package documentation describes briefly how to bring up such a virtual CAN interface in Linux.

Two sockets are opened in the example: One for sending messages, the other for receiving them. The SerialPackager blocks are used to add/retrieve data to/from the messages.

Modelica_DeviceDrivers.Blocks.Examples.TestInputSpaceMouse

Information

Basic example of using inputs from a 3Dconnexion SpaceMouse.

Important for Linux users: In order to work under Linux it is needed that the linux drivers provided by 3Dconnexion are installed and running.

Modelica_DeviceDrivers.Blocks.Examples.TestInputJoystick

Information

Basic example of using inputs from a joystick/gamepad device.

Modelica_DeviceDrivers.Blocks.Examples.TestInputKeyboard

Information

Basic example of using a keyboard as input device.

Modelica_DeviceDrivers.Blocks.Examples.TestInputKeyboardKey

Information

Basic example of using a keyboard as input device. For this example the parameter keyCode is set to the "space" key. Therefore, pressing space while the simulation is running will turn the output of the block to true, otherwise it is false

Modelica_DeviceDrivers.Blocks.Examples.TestHardwareIOComedi

Information

Important: Works only under Linux. The reason for this is, that the interfaced Comedi device drivers are only available for Linux.

Example tested with USB-DUX D. Assuming input channels are electrical connected to corresponding output channels we should read what we wrote
