Example Projects

UL for Linux includes example projects you can run with MCC hardware.

UL for Linux example projects are installed into an "examples" folder as part of the project make and are ready to run.
Connect a supported Measurement Computing DAQ device to your system before running an example. Perform the following steps to run a UL for Linux example from a terminal window:

1. Open a terminal window in the UL for Linux examples folder directory.
2. Enter ./filename.
   For example, enter ./AIn to run the analog input example.

Users can also choose to import the example code into an IDE, such as Eclipse, and run the examples from that environment.

The UL for Linux package includes the following example projects:

UL for Linux Example	Description
AIn	Reads an A/D input channel. Demonstrates the use of ulAIn().
AInScan	Scans a range of A/D input channels, and stores the data in an array. Demonstrates the use of ulAInScan() and ulAInScanStop().
AInScanWithEvents	Performs an A/D scan using events to determine when data is available or when the acquisition is complete. The example also demonstrates how to retrieve the data when it becomes available. Demonstrates the use of ulEnableEvent(), ulAInScanWait(), and ulAInScanStop().
AInScanWithQueue	Creates a queue that sets individual channel ranges for an A/D scan. Demonstrates the use of ulAInLoadQueue(), ulAInScan(), and ulAInScanStop().
AInScanWithTrigger	Scans a range of A/D channels when a trigger is received, and stores the data in an array. This example shows how to obtain and configure trigger options. Demonstrates the use of ulAInScan() and ulAInScanStop().
AInScanIepe	Enables IEPE mode for a range of A/D input channels, and scans the specified A/D input channels. Demonstrates the use of ulAInScan() and ulAInScanStop().
AOut	Writes a specified value to a D/A output channel. Demonstrates the use of ulAOut().
AOutScan	Performs a D/A scan. Data can be viewed with an oscilloscope or meter. Demonstrates the use of ulAOutScan() and ulAOutScanStop().
CIn	Sets the initial value of a counter and counts events. Demonstrates the use of ulCIn() and ulCClear().
CInScan	Scans a range of counter channels. Demonstrates the use of ulCInScan() and ulCInScanStop().
CInScanWithEncoder	Scans a range of encoder channels. Demonstrates the use of ulCInScan(), ulCConfigScan(), and ulCInScanStop().
DaqInScan	Simultaneously acquires analog, digital, and counter data. Demonstrates the use of ulDaqInScan(), ulDaqInScanStatus, and ulDaqInScanStop().
DaqInScanWithTrigger	Sets up a trigger function, and simultaneously acquires analog, digital, and counter data when the trigger is received. Demonstrates the use of ulDaqInScan() and ulDaqInScanStop().
DaqOutScan	Simultaneously outputs analog and digital data. Demonstrates the use of ulDaqOutScan(), ulDaqOutScanStatus, and ulDaqOutScanStop().
DBitIn	Configures multiple digital bits for input and reads the bit values. Demonstrates the use of ulDConfigBit() and ulDBitIn().
DBitOut	Writes a specified value to multiple digital output bits. Demonstrates the use of ulDConfigBit() and ulDBitOut().
DIn	Configures a port for input and reads the port value. Demonstrates the use of ulDConfigPort() and ulDIn().
DInScan	Configures a port for input and continuously reads it. Demonstrates the use of ulDConfigPort(), ulDIn(), and ulDInScanStop().
DOut	Configures a port for output and writes a specified value. Demonstrates the use of ulDConfigPort() and ulDOut().
DOutScan	Configures the port direction and outputs digital data. Demonstrates the use of ulDConfigPort(), ulDOutScan(), and ulDOutScanStop().
RemoteNetDiscovery	Discovers remote Ethernet DAQ devices. Demonstrates the use of ulGetNetDaqDeviceDescriptor() and ulFlashLed().
TIn	Reads a temperature input channel. Demonstrates the use of ulTIn().
TmrPulseOut	Generates an output pulse at a specified duty cycle and frequency. Demonstrates the use of ulTmrPulseOutStart() and ulTmrPulseOutStop().
