short * overflow,

Once you open the driver and set up some channels, you can call the

usb_tc08_run

routine. The driver will then begin to continually take readings from the USB TC-08. Use

the

usb_tc08_get_temp

routine to retrieve readings from the driver's buffer

periodically. You must call the function at least once per minute to avoid losing data (the

driver's buffer is circular, so the oldest readings will be overwritten first).

Streaming mode

relies on the driver to buffer readings without interruption. If the driver

does not get enough share of the PC's processor time (the most frequent cause of which

is too many applications running at the same time), readings will be dropped and the

sample buffer will be padded with

QNaN floating integers.

Warning: The padding of the buffer is also dependent on the performance of the PC and

under very heavy processor loading, padding may not always be accurate.
