Example
The following code is a fragment of a C application demonstrating how to use legacy
mode with the USB TC-08 driver:
//==========================================================
// Setting up and running the unit in Legacy mode
// This is designed to make it easier to adapt code written
// for the Serial TC08 for use with the USB TC08
//==========================================================
usb_tc08_set_mains
(handle,
0
);
// use 50Hz mains noise rejection
for
(channel =
1
; channel <
9
; channel++)
{
// set each channel up as a type K thermocouple
// switch off filtering for all channels
usb_tc08_legacy_set_channel
(handle, channel,
'K'
,
0
);
}
usb_tc08_legacy_run
(handle);
last_cycle_no =
0
;
no_of_readings =
0
;
while
(no_of_readings <
50
)
// collect 50 readings
{
usb_tc08_legacy_get_cycle
(handle, &this_cycle_no);
if
(last_cycle_no != this_cycle_no)
{
last_cycle_no = this_cycle_no;
no_of_readings++;
for
(channel =
1
; channel <
9
; channel++)
{
usb_tc08_legacy_get_temp
( &reading[channel],
handle,
channel,
0
);
}
// now do something with the readings
// check that they have not overflowed
// by comparing each reading with 2147483647L
// or LONG_MAX (include limits.h)
usb_tc08_legacy_get_cold_junction
(handle, &cold_junction);
// now do something with the cold junction temperature
}
}
usb_tc08_stop
(handle);
