3.2.4 Legacy mode
Legacy mode is designed to aid developers who have already written code for the serial version of the
TC-08 and are not yet ready to rewrite their code for the
Streaming
or
Get Single
modes available with
the USB version. The legacy support is going to be phased out and will eventually be removed from
the driver altogether. If you want full support in the future, use the Streaming or Get Single modes.
To allow code to be easily developed for both the serial version and the USB version of the TC-08, all
the function names have been changed. The
usb_tc08_legacy_set_channel
function no longer
supports offset and gain - this is now stored only as calibration information in the unit itself. The legacy
routines will be familiar if you previously used the serial TC-08, however, the following changes should
be made to convert legacy applications:
Reference the new Header file
Reference the new Library file
Place the new
DLL
in the directory of the application
Set the mains frequency
Run and stop the unit
Store a handle returned from
usb_tc08_open_unit
instead of using the serial port number
