CMD_xpci3xxx_InitAnalogOutput

#define CMD_xpci3xxx_InitAnalogOutput   _IOR(xpci3xxx_MAGIC, 50,long)

Initializes one analog output channel.

Parameters

[in]

uint8_t

arg[2]

• arg[0] Channel number of the output to be initialized
• arg[1] Voltage mode of the analog output
  • ADDIDATA_BIPOLAR: 0: -10V - +10V
  • ADDIDATA_UNIPOLAR:1: 0V - +10V

Return values

0	: Success
1	: Internal error
2	: Wrong channel number
3	: Wrong voltage mode
4	: A conversion is already started

CMD_xpci3xxx_ReadAnalogOutputBit

#define CMD_xpci3xxx_ReadAnalogOutputBit   _IOR(xpci3xxx_MAGIC, 51,long)

Returns the EOC bit.

Reads the EOC (End Of Conversion) bit of the analog output. This bit is set by the hardware to indicate that a conversion is finished.

Parameters

[out]

uint8_t

*arg = 0: no analog output conversion finished | 1: analog output conversion finished

Return values

0	: Success
1	: Internal error

CMD_xpci3xxx_WriteAnalogOutputValue

#define CMD_xpci3xxx_WriteAnalogOutputValue   _IOR(xpci3xxx_MAGIC, 52,long)

Writes to the analog output channel.

Parameters

[in]

uint32_t

arg[2]

• arg[0] Channel number of the output to be initialized
• arg[1] New value

Return values

0	: Success
1	: Internal error
2	: Wrong channel number
3	: Wrong write value
