Detailed Description

[AnalogInput] Interface for accessing analog input of a DAQFlex board from Measurement Computing.

Note

In readData() we might want to reduce the bulk_transfer timeout, once RELACS thread timing gets smoother.

int prepareRead ( InList &  traces )

virtual

Prepare analog input of the input traces traces on the device. If an error ocurred in any trace, the corresponding errorflags in InData are set and a negative value is returned. This function assumes that traces successfully passed testRead(). The channels in traces are not sorted.

int startRead ( QSemaphore *  sp = 0, QReadWriteLock *  datamutex = 0, QWaitCondition *  datawait = 0, QSemaphore *  aosp = 0  )

virtual

Start analog input of the input traces on the device after they were prepared by prepareRead(). If an error ocurred in any channel, the corresponding errorflags in the InData structure are filled and a negative value is returned. Also start possible pending acquisition on other devices that are known from take().

int convertData ( void  )

virtual

Convert data from and push them to the traces. Returns the number of new data values that were added to the traces (sum over all traces). If an error ocurred in any channel, the corresponding errorflags in the InList structure are filled and a negative value is returned.

Implements AnalogInput.

int stop ( void  )

virtual

Stop any running ananlog input activity, but preserve all so far read in data. The next call to readData() will return the data. Returns zero on success, otherwise one of the flags NotOpen, InvalidDevice, ReadError.

int testReadDevice ( InList &  traces )

protectedvirtual

Device driver specific tests on the settings in sigs for each input channel. Before this function is called, the validity of the settings in sigs was already tested by testReadData(). This function should test whether the settings are really supported by the hardware. If an error ocurred in any trace, the corresponding errorflags in the InData are set and a negative value is returned. The channels in sigs are not sorted. This function is called by testRead().
