Detailed Description

[Device] Controlls the PFI pins of a NI M-series daq-board via comedi.

Author

Jan Benda The signal routing is routed to the channel channel on the PFI subdevice (subdevice no. 7) of a national instruments M-series board.

Use for routing either the following integer values or the names without the "NI_PFI_OUTPUT_" part (from comedi.h):

enum ni_pfi_routing {
         NI_PFI_OUTPUT_PFI_DEFAULT = 0,
         NI_PFI_OUTPUT_AI_START1 = 1,
         NI_PFI_OUTPUT_AI_START2 = 2,
         NI_PFI_OUTPUT_AI_CONVERT = 3,
         NI_PFI_OUTPUT_G_SRC1 = 4,
         NI_PFI_OUTPUT_G_GATE1 = 5,
         NI_PFI_OUTPUT_AO_UPDATE_N = 6,
         NI_PFI_OUTPUT_AO_START1 = 7,
         NI_PFI_OUTPUT_AI_START_PULSE = 8,
         NI_PFI_OUTPUT_G_SRC0 = 9,

         NI_PFI_OUTPUT_AI_EXT_MUX_CLK = 12,
         NI_PFI_OUTPUT_GOUT0 = 13,
         NI_PFI_OUTPUT_GOUT1 = 14,
         NI_PFI_OUTPUT_FREQ_OUT = 15,
         NI_PFI_OUTPUT_PFI_DO = 16,
         NI_PFI_OUTPUT_I_ATRIG = 17,
         NI_PFI_OUTPUT_RTSI0 = 18,
         NI_PFI_OUTPUT_PXI_STAR_TRIGGER_IN = 26,
         NI_PFI_OUTPUT_SCXI_TRIG1 = 27,
         NI_PFI_OUTPUT_DIO_CHANGE_DETECT_RTSI = 28,

Constructor & Destructor Documentation

ComediNIPFI

(

void

)

Create a new ComediNIPFI without opening a device.

References ComediNIPFI::initOptions().

ComediNIPFI	(	const string &	device,
		const Options &	opts
	)

Open comedi specified by its device file device.

References ComediNIPFI::open().

~ComediNIPFI ( void  )

virtual

Close the comedi driver.

Member Function Documentation

int open ( const string &  device )

overridevirtual

Open the PFI device specified by device.

Returns

zero on success, or InvalidDevice (or any other negative number indicating the error).
