PCIS-DASK Application Hints

5.4.2 Synchronous Continuous Digital output programming

Scheme

This section described the function flow typical of synchronous digital output

operation. While performing continuous DO operation, the DO configuration

function has to be called at the beginning of your application. In addition, for

synchronous DO operation, the SyncMode argument in continuous DO

functions for synchronous mode has to be set as SYNCH_OP.

DO_xxxx_Config

(xxxx means the card type,

e.g. DO_7200_Config)

DO_Cont WritePort

With SyncMode=SYNCH_OP

[Example Code Fragment]

card = Register_Card(PCI_7200, card_number);

…

DO_7200_Config(card, TRIG_INT_PACER, OREQ_DISABLE,

OTRIG_LOW);

DO_AsyncDblBufferMode (card, 0); //non-double-buffered mode

DO_ContWritePort(card, 0, DoBuf, count, 1, (F64)sample_rate,

SYNCH_OP);

…

Release_Card(card);
