3.3.4.7 usb_tc08_legacy_get_cycle

short usb_tc08_legacy_get_cycle (long * cycle,

short handle)

This routine gives the number of complete cycles of readings taken from a particular USB TC-08.

Calling

usb_tc08_legacy_get_temp

causes the most recent reading for the specified channel to be

returned immediately. If you wish to record values only when the driver has taken a new reading, you

can use this routine to find out how many complete cycles of readings the driver has taken. Then you

can call

usb_tc08_legacy_get_temp

, but only when the cycle has been incremented.

Arguments:

handle

- Specifies a USB TC-08 unit.

cycle

- Pointer to a location where the cycle number is to be stored.

Returns:

- Use

usb_tc08_get_last_error

- Legacy get cycle successful.

Tip: Do not test for an exact cycle number; instead, test for a different cycle number as your application

may have missed readings. See the

Legacy mode

section for an example.

Note: This function should not be called unless you are operating the USB TC-08 in legacy mode,

having called

usb_tc08_legacy_run
