Counter I/O

Functions

UL: cbCIn()*, cbCIn32(), cbCLoad()**, cbCLoad32()**

UL for .NET: CIn()*, CIn32(), CLoad()**, CLoad32()**

Python for Windows: c_in()*, c_in_32(), c_load()**, c_load_32()**

*Although cbCIn()/CIn()/c_in() are valid for use with this counter, cbCIn32()/CIn32()/c_in_32() may be more appropriate, since the values returned may be greater than the data types used by cbCIn() and CIn() can handle.

**cbCLoad()/cbCLoad32(), CLoad()/CLoad32(), c_load()/c_load_32() only accept Count=0. These functions are used to reset the counter.

CounterNum

1

Count

232-1 when reading the counter.

0 when loading the counter

cbCLoad() and cbCLoad32() / CLoad() and CLoad32() are used only to reset the counter for this board to 0. No other values are valid.

The Basic signed integers guidelines in the Digital Input/Output Hardware topic apply when using cbCIn() or CIn() for values greater than 32,767 and when using cbCIn32() or CIn32() for values greater than 2,147,483,647.

RegNum

LOADREG1

Event Notification

Functions

UL: cbEnableEvent(), cbDisableEvent()

UL for .NET: EnableEvent(), DisableEvent()

Miscellaneous

Functions

UL: cbFlashLED()

UL for .NET: FlashLED()

Python for Windows: flash_led()

Causes the LED on a USB device to blink. When you have several USB devices connected to the computer, use this function to identify a particular device by making its LED blink.

Hardware considerations

Resolution

When configured for single-ended mode, the resolution of the data is 11 bits (data values between 0 and 2,047). However, the Universal Library maps this data to 12-bit values, so the range of data is no different from the differential configuration. Consequently, the data returned contains only even numbers between 0 and 4,094 when the NOCALIBRATEDATA option is used.

BURSTIO

Allows higher sampling rates (up to 8000 Hz) for sample counts up to 4096. Data is collected into the miniLAB's local FIFO. Data is collected into the USB device's local FIFO. Data transfers to the PC don't occur until the scan completes. For BACKGROUND scans, the Count and Index returned by cbGetStatus() and GetStatus() remain 0, and STATUS=RUNNING until the scan finishes. The Count and Index are not updated until the scan is completed. When the scan is complete and the data is retrieved, cbGetStatus() and GetStatus() are updated to the current Count and Index, and Count = IDLE.

BURSTIO is the default mode for non-CONTINUOUS fast scans (aggregate sample rates above 1000 Hz) with sample counts up to 4096. BURSTIO mode allows higher sampling rates (up to 8000 Hz) for sample counts up to 4096. Non-BURSTIO scans are limited to a maximum of 1200 Hz. To avoid the BURSTIO default, specify BLOCKIO mode.

Continuous scans

When running cbAInScan() with the CONTINUOUS option, you should consider the packet size and the number of channels being scanned. In order to keep the data aligned properly in the array, make the total number of samples an integer multiple of the packet size and the number of channels.

Concurrent operations

Concurrent operations on a particular USB device are not allowed. If you invoke a UL or UL for .NET function on a USB device while another function is running on that USB device, the ALREADYACTIVE error is returned.
