Member Function Documentation

bool FPGAConf

(

System::String^

FileName

)

[virtual]

Configures FPGA (DAC board).

Parameters:

FileName

.bit FPGA programming file

Returns:

True if successful

Reimplemented in dacBoardVirtexII, and dacBoardVirtex4.

float SamplingFreq

(

float

SamplingFreq

)

[virtual]

Sets DAC sampling frequency.

Parameters:

SamplingFreq

Value Meaning <=0 External clock xx xx MHz

VirtexII boards have a programmable clock which can operate on a large set of frequencies from 20 to 125 MHz. However Virtex4 clock is limited to 104 or 52 MHz.

Returns:

Value	Meaning
-1	Error
0	DCMs locked at external clock
xx	DCMs locked at xx MHz

Reimplemented in dacBoardVirtexII, and dacBoardVirtex4.

int SDRAMWrite

(

array< System::Int16 >^

Data

)

Writes data to SDRAM.

Parameters:

Data

Array containing data to be written.

The data must be organized as shown: samples #1 of all channels, samples #2 of all channels, etc.

Returns:

Number of samples succesfully written.

array< System::Int16 > SDRAMRead

(

unsigned int

SamplesPerChannel

)

Reads data from SDRAM.

Parameters:

SamplesPerChannel

Number of samples per channel to be acquired.

Returns:

An array containing acquired samples.

The data is organized as shown: samples #1 of all channels, samples #2 of all channels, etc.

bool ChannelConf	(	int	ChannelMask,
		unsigned int	SamplesPerChannel
	)

Configures DAC channels.

Parameters:

	ChannelMask	Binary mask to indicate enabled channels (eg. Binary 1 on LSB enables channel 1).
	SamplesPerChannel	Number of samples that each enabled channel must play back.

Returns:

True if successful.

bool Play

(

)

Starts data playback.

Returns:

True if successful.

bool ChannelDeconf

(

)

Deconfigures DAC channels.

Stops playback and clears list of channels

Returns:

True if successful.
