Collecting windowed or streaming data

This method causes the device to start sampling. Samples are stored in the driver's

buffer. In windowed mode, the buffer will always contain the requested number of

samples, but generally only a subset of these are new data. In streaming mode, new

data are returned continuously.

Open the data logger with one of the HRDLOpenUnit calls

Set mains noise rejection with HRDLSetMains

Set the analog or/and digital channels

Set the sample interval with HRDLSetInterval

Start the unit collecting samples by calling HRDLRun with method = BM_WINDOW or

BM_STREAM

Loop

Repeat Loop until ready (HRDLReady)
