DAPL Configuration Commands
DAPL includes over 100 built-in commands in the following categories. |
|---|
Input/Output Configuration
TIME t- Sets the sampling time equal to t microseconds on input.
Sets the output update time to t microseconds on output. COUNT n- Specifies that n samples should be acquired on input.
Specifies that n updates should occur on output.
If this command is omitted, acquisition or update continues until the DAP receives a STOP command. HTRIGGER- Selects the hardware triggering mode of an input or output procedure - OFF, ONESHOT, or GATED.
CLOCK- Selects internal or external hardware clocking of an input or output procedure.
UPDATE- Selects continuous mode updates or burst mode updates in an output procedure.
CYCLE- Selects automatically repeating block updates in an output procedure.
MASTER and SLAVE- Select master and slave DAPs in a synchronized system.
SET IPIPE i t n g- Sets input channel pipe i to sample physical input pin n with gain g. The parameter t selects the channel type -- S for single ended, D for differential, and B for binary. The number n following type B is zero. B0 here represents the onboard 16-bit binary input port. Gain g is optional.
SET OPIPE o t n- Sets output channel pipe o to update physical output n. Values for t and n are A0, A1, and B0 to designate the onboard analog outputs and the onboard 16-bit binary output port.
IDEFINE l n- Begins definition of an n-channel input procedure labeled l. An input procedure configures input channel pipes, specifies sampling rates, etc.
ODEFINE l n- Begins definition of an n-channel output procedure labeled l. n is 1 or 2. An output procedure configures synchronous output channel pipes, specifies update rates, etc.
PDEFINE l- Begins definition of a processing procedure labeled l. A processing procedure specifies a list of tasks that run continuously once the procedure is started.
END- Ends the most recently begun procedure definition.
