Sandbox/Graph Not Visible

Post by jsmad »

I'm new to the Phidgets ecosystem (impressed by what I've seen so far of the system components and the support for various programming languages). I am running a BLDC Phidget (DCC1120_0), but in the Phidget Control Panel for both position and velocity control mode, I do not see the motion graph (see attached photo). Has that been removed in recent FW versions? Or am I missing some system setting? I am on a Mac OS.

Graphing is only available through the Phidget Control Panel on Windows.

Follow-up question: does the fact that graphing is not available on a Mac mean that I don't have access to the variable "channel.getExpectedVelocity()"? I have been trying for hours to figure out how to access this variable, but python keeps throwing the following exception:

Or is there is something else I need to be doing to successfully access this variable? And yes, I have a "channel.setEnableExpectedVelocity(True)" line in my code which is being successfully set.

After setEnableExpectedVelocity(true), you will need to wait for the expected velocity to be reported by the device, which happens at the set data interval, and only when velocity changes. Are you seeing the ExpectedVelocityChange event fire?

error 0x33 is Unknown Value, which means that the value hasn't been reported by the device yet.
