| Task : Enableor disable the selected pulse encoder (b_PulseEncoderNbr) |
| from selected module (b_ModulNbr). Each input pulse |
| decrement the pulse encoder counter value from 1. |
| If you enabled the interrupt (b_InterruptHandling), a |
| interrupt is generated when the pulse encoder has run |

| Input Parameters : unsigned char_ b_BoardHandle : Handle of board APCI-1710|

| configure (0 to 3) |
| unsigned char_ b_PulseEncoderNbr : Pulse encoder selection |
| (0 to 3) |
| unsigned char_ b_CycleSelection : APCI1710_CONTINUOUS: |
| Each time the |
| counting value is set|
| on "0", the pulse |
| encoder load the |
| start value after |
| the next pulse. |
| APCI1710_SINGLE: |
| If the counter is set|
| on "0", the pulse |
| encoder is stopped. |

APCI1710_PULSEENCODER_WRITE
Writes a 32-bit value (ul_WriteValue) into the selected|
| pulse encoder (b_PulseEncoderNbr) from selected module |
| (b_ModulNbr). This operation set the new start pulse |
| encoder value.
APCI1710_PULSEENCODER_READ
| Input Parameters : unsigned char_ b_BoardHandle : Handle of board APCI-1710|
| CRAREF() unsigned char_ b_ModulNbr : Module number to |
| configure (0 to 3) |
| data[1] unsigned char_ b_PulseEncoderNbr : Pulse encoder selection |
| (0 to 3)
APCI1710_PULSEENCODER_WRITE
data[2] ULONG_ ul_WriteValue : 32-bit value to be |
| written |
+----------------------------------------------------------------------------+
| Output Parameters : unsigned char *_ pb_Status : Pulse encoder status. |
| 0 : No overflow occur|
| 1 : Overflow occur
PULONG_ pul_ReadValue : Pulse encoder value | |
+----------------------------------------------------------------------------+
| Return Value : 0: No error |
| -1: The handle parameter of the board is wrong |
| -2: Module selection is wrong |
