usb_tc08_get_minimum_interval_ms

long usb_tc08_get_minimum_interval_ms (short handle)

This routine returns the minimum sampling interval (or fastest millisecond interval) that

the unit can achieve in its current configuration. The configuration is defined by calling

usb_tc08_set_channel()

Arguments:

handle

- Specifies the USB TC-08 unit.

Returns:

- Use

usb_tc08_get_last_error.

Minimum

Interval

- Minimum sampling interval for current setup (in

milliseconds).

Note: The USB TC-08 can sample, from a single channel, at a rate of 10 samples per

second. The absolute minimum sampling interval, with all 8 channels and the cold

junction enabled, is 900 ms. You must set up all the channels that you wish to use before

calling this routine.

3.3.2.8

usb_tc08_get_unit_info

short usb_tc08_get_unit_info(

short handle,

USBTC08_INFO * info)

This routine gets the unit information and copies it to the

USBTC08_INFO structure,

declared in the usbtc08.h header file. If you pass zero to the function as the handle, only

the driver version member will be valid, but the function will return 1 (success.)

Arguments:

handle

- Specifies the TC-08 unit.

info

- A pointer to a structure containing unit information.

Returns:

- Use

usb_tc08_get_last_error

- Routine was successful.

You must assign the correct value to the

size

field of your

USBTC08_INFO structure

before calling this routine. For example, in C, if

devinfo

is your structure, use this code:

devinfo.size = sizeof(USBTC08_INFO);

usb_tc08_get_unit_info(hTC08, &devinfo);
