usb_tc08_get_single
short usb_tc08_get_single( short handle,
float * temp,
short * overflow_flags,
short units)
You must set up the channels before calling this function. You must
not
have put the unit
into Streaming mode with
usb_tc08_run
, as this will cause
usb_tc08_get_single
to
fail. The function will convert all readings on demand. For more details and an example
see the
Get Single mode
section.
Arguments:
handle
- Specifies the USB TC-08 unit.
temp
- Pointer to an array of length [9]. There are 9
channels on the USB TC-08 (8 + cold junction) and
the readings are always placed in the array
subscript corresponding to the channel number.
Channels which are not enabled are filled with
QNaN values.
overflow_flags
- Pointer to a variable containing a set of bit flags that
are set high when an overflow occurs on a particular
channel. An overflow occurs when the input signal is
higher than the measuring range of the USB TC-08.
The lowest significant bit (bit 0) represents channel
0 (the cold juction channel) and bit 8 represents
channel 8 (the last thermocouple channel). Bitwise
comparisons should be performed to determine the
overflow state of each channel.
units
- Specifies the temperature units for returned data:
0: USBTC08_UNITS_CENTIGRADE
1: USBTC08_UNITS_FAHRENHEIT
2: USBTC08_UNITS_KELVIN
3: USBTC08_UNITS_RANKINE
Returns:
0
- An error occurred, use
usb_tc08_get_last_error
to
get the code.
1
- The function succeeded.
