How to tell if your Picoscope has been disconnected(!)

Postby jon@ktizo.co.uk » Thu Jul 19, 2012 9:30 am

Hi,
I have an application where I need to identify if a 2205 Picoscope has been disconnected from the USB port (or if the USB port has died). I thought this would be easy, but I can't find a straightforward way of doing it.

get_unit_info (and all the other commands I've tried) seem to work quite happily without the Picoscope being connected, once the unit is opened.I guess lots of status information is stored by the driver.

Does anyone know a way of doing it?

Many thanks,
Jon.

We have added a function into the driver to match our newer scopes.

Code: Select all
short ps2000PingUnit( short handle )


Zero return value indicates the device is disconnected

This command hasn't made it to the documentation yet.
