Detailed Description

Function Documentation

i_APCIE3660_Read4DigitalInputs()

int i_APCIE3660_Read4DigitalInputs	(	uint8_t	boardId,
		uint8_t *	portValues
	)

Read 4 digital inputs of the board

Parameters

[in]	boardId	Target board index
[out]	portValues	Status of the digital inputs

Return values

0	No error
-1	The boardId is wrong
-14	An error occurred while calling the IOCTL function

i_APCIE3660_Read1DigitalInput()

int i_APCIE3660_Read1DigitalInput	(	uint8_t	boardId,
		uint8_t	input,
		uint8_t *	inputValue
	)

Read 1 digital input of the board

Parameters

[in]	boardId	Target board index
[in]	input	Digital input (0 to 7)
[out]	inputValue	Status of the digital input

Return values

0	No error
-1	The boardId is wrong
-2	The input is wrong
-14	An error occurred while calling the IOCTL function

i_APCIE3660_SetDigitalOutputMemoryOn()

int i_APCIE3660_SetDigitalOutputMemoryOn

(

uint8_t

boardId

)

Enables the digital output memory When digital output memory is enabled, the active channels stay active until a SetDigitalOutputOff function is called. When digital output memory is disabled, the active channels are reset at each call of a SetDigitalOutputOn function. SetXDigitalOutputOff functions return an error.

Parameters

[in]

boardId

Target board index

Return values

0	No error
-1	The boardId is wrong
-14	An error occurred while calling the IOCTL function

i_APCIE3660_SetDigitalOutputMemoryOff()

int i_APCIE3660_SetDigitalOutputMemoryOff

(

uint8_t

boardId

)

Disables the digital output memory When digital output memory is enabled, the active channels stay active until a SetDigitalOutputOff function is called. When digital output memory is disabled, the active channels are reset at each call of a SetDigitalOutputOn function. SetXDigitalOutputOff functions return an error.

Parameters

[in]

boardId

Target board index

Return values

0	No error
-1	The boardId is wrong
-14	An error occurred while calling the IOCTL function

i_APCIE3660_Set4DigitalOutputsOn()

int i_APCIE3660_Set4DigitalOutputsOn	(	uint8_t	boardId,
		uint8_t	mask
	)

Permits to set digital outputs of the board

Parameters

[in]	boardId	Target board index
[in]	mask	Digital output port to set (0 to 15)

Return values

0	No error
-1	The boardId is wrong
-2	The mask value is wrong
-14	An error occurred while calling the IOCTL function

i_APCIE3660_Set4DigitalOutputsOff()

int i_APCIE3660_Set4DigitalOutputsOff	(	uint8_t	boardId,
		uint8_t	mask
	)

Permits to reset digital Outputs of the board

Parameters

[in]	boardId	Target board index
[in]	mask	Digital output port to reset (0 to 15)

Return values

0	No error
-1	The boardId is wrong
-2	The mask value is wrong
-3	Digital output memory not set - Cannot set outputs to 0
-14	An error occurred while calling the IOCTL function

i_APCIE3660_Set1DigitalOutputOn()

int i_APCIE3660_Set1DigitalOutputOn	(	uint8_t	boardId,
		uint8_t	outputChannel
	)

Sets 1 digital output to HIGH

Parameters

[in]	boardId	Target board index
[in]	outputChannel	Digital output to set (0 to 3)

Return values

0	No error
-1	The boardId is wrong
-2	The outputChannel is wrong
-14	An error occurred while calling the IOCTL function

i_APCIE3660_Set1DigitalOutputOff()

int i_APCIE3660_Set1DigitalOutputOff	(	uint8_t	boardId,
		uint8_t	outputChannel
	)

Sets 1 digital output to LOW

Parameters

[in]	boardId	Target board index
[in]	outputChannel	Digital output to reset (0 to 3)

Return values

0	No error
-1	The boardId is wrong
-2	The outputChannel is wrong
-3	Digital output memory not set - Cannot set outputs to 0
-14	An error occurred while calling the IOCTL function
