short usb_tc08_legacy_set_channel (short handle,

short channel,

char tc_type,

short filter_factor,

short offset,

short slope)

Call this routine once for each channel that you would like to take readings from. You can

do this any time after calling

usb_tc08_open_unit

Arguments:

handle

- Specifies the USB TC-08 unit.

channel

- Specifies which channel you want to set the details

for: This should be between 0 and 8.

tc_type

- Specifies what type of thermocouple is connected to

this channel. Set to one of the following characters

'B', 'E', 'J', 'K', 'N', 'R', 'S', 'T.' Use a space in quotes to

disable the channel.

filter_factor

- Specifies the size of the median filter. Each time the

driver takes a reading from this channel, it updates

the filtered value by adding a reading to a median

filter. The filter factor can be set to any value between

0 - 255 (0 or 1 turns filtering off).

filter_factor

- These parameters are provided for backward

compatibility with the serial TC-08 and have no effect

when used with the USB TC-08.

Returns:

- Use

usb_tc08_get_last_error

- Legacy set channel successful.

Note: Do not call this function unless you are operating the USB TC-08 in legacy mode,

having called
