cbCLoad32()

Loads a value into the specified counter register.

For some devices, the value is directly loaded into the count register. For other devices, the value is first loaded into the load or hold register. Once the counter is enabled, the count is loaded from the appropriate register, generally on the first valid pulse.

Function Prototype

C/C++

int cbCLoad32(int BoardNum, int RegNum, unsigned long LoadValue)

Visual Basic

Function cbCLoad32(ByVal BoardNum&, ByVal RegNum&, ByVal LoadValue&) As Long

Arguments

BoardNum

The number associated with the board when it was installed with InstaCal or created with cbCreateDaqDevice(). BoardNum may be 0 to 99.

RegNum

The register to load the value into. Set it to one of the constants in the "RegNum argument values" section below.

LoadValue

Value to be loaded into RegNum.

Returns

Error code or 0 if no error occurs

RegNum argument values

LOADREG1 to LOADREG20	Load registers 1 through 20. This may span several chips.
HOLDREG0 to HOLDREG20	Hold registers 0 through 20. This may span several chips. (9513 only)
ALARM1CHIP1	Alarm register 1 of the first counter chip. (9513 only)
ALARM2CHIP1	Alarm register 2 of the first counter chip. (9513 only)
ALARM1CHIP2	Alarm register 1 of the second counter chip. (9513 only)
ALARM2CHIP2	Alarm register 2 of the second counter chip. (9513 only)
ALARM1CHIP3	Alarm register 1 of the third counter chip. (9513 only)
ALARM2CHIP3	Alarm register 2 of the third counter chip. (9513 only)
ALARM1CHIP4	Alarm register 1 of the fourth counter chip. (9513 only)
ALARM2CHIP4	Alarm register 2 of the fourth counter chip. (9513 only)
COUNT1 to COUNT4	Used to initialize the counter. (LS7266 only) Load this value FIRST if using the PRESETx or PRESCALERx registers.
PRESET1 to PRESET4	Used to set the upper limit of the counter in some modes. (LS7266 only)
PRESCALER1 to PRESCALER4	Used for clock filtering (valid values: 0 to 255). (LS7266 only) If using the PRESETx or COUNTx registers, load this value LAST.
MINLIMITREG0 to MINLIMITREG7	Min limit register. (USB-CTR Series and USB-QUAD08 only)
MAXLIMITREG0 to MAXLIMITREG7	Max limit register. (USB-CTR Series and USB-QUAD08 only)
OUTPUTVAL0REG0 to OUTPUTVAL0REG7	Output register 0. (USB-CTR Series only)
OUTPUTVAL1REG0 to OUTPUTVAL1REG7	Output register 1. (USB-CTR Series only)

Notes

cbCLoad() vs cbCLoad32()
Although the cbCLoad() and cbCLoad32()functions perform the same operation, cbCLoad32() is the preferred function to use.
The only difference between the two is that cbCLoad() loads a 16-bit count value, and cbCLoad32() loads a 32-bit value. The only time you need to use cbCLoad32() is to load counts that are larger than 16-bits (counts > 65,535).
