I wouldn't intuitively think so, I would expect it to bounce back, especially when quiet mode is turned off. 2m is not very far, I don't expect there to be problems, but I've never tested that exact scenario myself. Do you have more than 1 DST1200 you could verify has the same behaviour? A good way ...

The array will only be empty when the sonar is failing to receive the signal back, meaning it is measuring too far away, or is hitting something that doesn't reflect the sound back. The chances of this happening increase greatly with "QuietMode" turned on, so as a starting point if you hav...

Good point, I will poke the bear

Looks like you will want to add: digitalInput0.setIsHubPortDevice(True) when addressing the device prior to opening it. The IsHubPortDevice property is used to differentiate between opening a channel that directly monitors the wire on the VINT port, versus opening an addressable VINT device on the s...

My most immediate thought is to high-pass filter the loadcell data to look for spikes. Referencing the absolute value of the signal prior to and following the high-pass event would allow you to see whether mail was added or removed.

Albeit yes this doesnt solve the stuck in door problem

Though that might make some sense in some applications, one of the main benefits of the non-timeout open() is that you can call it and not worry about timeouts. There are a lot of applications for opening a device before it is plugged in, and being able to freely plug/unplug it as you see fit. I'm s...

This scenario has to do with the calculation of the sensorValue from the actual voltage. The voltage is typically limited to 0-5V, so the bounds of the sensor (ie min lux and max lux from the 1127, or min temperature and max temperature for an 1114) need to be within that specification. The hardware...

This is done by calibrating the VoltageRatio to the loadcell, by taking measurements at various "known" forces. You can read up on it here: https://www.phidgets.com/docs/Calibrating_Analog_Sensors and further information on load cells can be found here: https://www.phidgets.com/docs/Load_C...

One possible explanation is that the high capacitance on the BLDC means when you unplug 12V, it can take several seconds for it to fully discharge and become unpowered. So if you disconnect 12V only momentarily, it might not fully reset.

The frequency is Variable but not in a controllable way. We vary the frequency depending on the Duty Cycle, in order to maintain ideal high/low times for the whole range of duty cycles. The spec is there to say it won't by more than 50kHz, but could be less, and is only applicable when the duty cycl...
