3.6.ARGUMENTS

The constants of the arguments are available as follows:

*In VB they are included in the example source file.

*In VC they are in the EncPciConst.h file in the VC folder; refer to the ReadMe.txt file.

*For DOS C/C++, the arguments, along with the headers of the functions, are in the file CPP\EncPci.h.

*For other environments, refer to the file More\EncPci.h. It contains the arguments, along with the headers of the functions, coded in C syntax. Transform the code to the proper syntax.

//CardHandle:

//Handle to current card as retrieved by the function GetCardHandle.

//ChipNumber:

#define Chip1 1 // Standard chip (always should be present). #define Chip2 2 // Optional chip.

//EncoderNumber:

//The codes of EncoderNumber are of three types:

//Type 1 codes (one encoder):

//Available for all the functions using EncoderNumber.

//Type 2 codes (pair of encoders):

//Available only for ResetPositionCounter and RequestPositionCounter.

//Type 3 code (all four encoders):

//Available only for RequestPositionCounter.

//Type 1 EncoderNumber codes (one encoder):

#define Encoder1 1 // First encoder in the selected chip (A or C). #define Encoder2 2 // Second encoder in the selected chip (B or D). // Type 2 EncoderNumber codes (pair of encoders):

#define Encoder3 3 // Both encoders in the selected chip (A+B or C+D).

//Type 3 EncoderNumber codes (all 4 encoders): #define Encoder4 4 // All 4 encoders (A+B+C+D).

//LedNumber:

#define LedYellow 1 #define LedRed 2

//ClocksPerCycle:

#define Clock1 1 // One clock per cycle. #define Clock2 2 // Two clocks per cycle. #define Clock4 4 // Four clocks per cycle.

//EventFlagSource:

#define EventFlagSourceNone 1 #define EventFlagSourceSetPoint 2 #define EventFlagSourceOverflow 3 #define EventFlagSourceIndex 4

//OnOffMode:
