Hi, I wonder if you may be seeing a detach related to EMI or power issues when switching the Solenoid. I would log detach events, and maybe enable library logging to help track down any events close to the crash. Library logging shouldn't impact performance, especially at INFO or lower level. https:...

I'm not sure how much help I can be. Phidget21 has been stable for a long time, so I suspect something in your program is causing the slow down, but it's very hard to know. What language is your program written in?

Do you have library logging enabled? I wonder if it may be related to a reference counting issue around a detach. I would enable library logging and see if you are getting any messages, especially a detach/attach cycle, or even a channel close. When you create the dictionary in the first place, are ...

The Mujie 600P/R really means 600 cycles per revolution. There are 4 pulses per quadrature cycle.

Do you have access to the source? It might be worthwhile upgrading to phidget22. Are you opening the Phidgets directly, or are you using the webservice? Do you happen to have library logging enabled? There may be errors that could point at a solution. Have you tried your program on another Windows 1...

Hi,

If you're on windows, you can use the phidget22native pip package (in place of phidget22) to install the phidget22.dll alongside the python library. Otherwise, you need the make sure the Phidget libraries are installed separately.

Ok, the constant attaching/detaching probably points to a defective MOT1102_1. You should contact support@phidgets.com for a replacement unit. Make sure that the HUB5000 has a sufficient power supply. The spatial doesn't draw much power, so it's unlikely to be an issue unless you're under voltage or...

Hi, The Spatial Phidget (MOT1102? MOT0110?) is attached to a HUB5000 and you are using the control panel on macOS (or Windows) to upgrade the firmware? The Spatial is attaching/detaching all the time? Are you able to open it at all? Can you provide the Phidget log from the HUB5000? Open it's web int...

What specific Phidget are you using? Is it a USB or VINT device?

Are there any error in: ~/Library/Logs/phidget22controlpanel.log ?

It's much more important to cover the sphere than to have many points. You could get a good calibration with 5 seconds worth of data, except that it may be difficult to rotate the spatial through the entire sphere in that much time. And the sphere doesn't need to be completely filled in - a single r...
