Re: Sensor value is ouside the valid range...

Thank you for the explanation of the underlying happenings. However, I am still left with the dilemma of separating signal from noise. In other words, a random reported error every now and then is probably not an error at all. However, a series of the same errors would likely indicate a missing sens...

getParent()

Python 2.7 The api documentation says I can do parent = ch.getParent() print("Parent: " + str(parent)) However, that just provides <Phidget22.Phidget.Phidget instance at 0x1011b2ea8> Attempting to iterate through the object shows a little bit more, but nothing really useful and there do no...

Sensor value is ouside the valid range...

Python 2.7, Phidget22. I am seeing a general issue using 0-5vdc voltage-input(classic) Phidgets. If I define a specif voltage-input Phidget (eg, an 1127) if the sensor value reaches 0, I receive "Sensor value is ouside the valid range" errors. In fact, it is not just my code, the Phidget C...

Re: P21 and P22 conflict?

I am on Phidget22 - Version 1.7 - Built Jul 6 2021 11:31:54 The code is a plugin for another program so I am not running the code directly. However, I can reliably attach the device with the plugin version based on p21, and then attach with the new plugin based on p22. As previously noted, the oppos...

Re: P21 and P22 conflict?

Ok... just verified. With the device unattached to anything, I can then attach it using P21. Then, using P22 I can also attach it and immediately see incoming data. Meanwhile, the P21 client does not get a detach event, so thinks it is still attached. But, gets no updates. Forcing the P21 client to ...

P21 and P22 conflict?

I have a case with a 1048-TemperatureSensor 4-Input where I can attach the phidget using the P21 libs and then attach it with the P22 libs. There is no indication of trouble with the P21client, but I stop receiving update events. Attempts to detach and reattach the phidget fail. If I attach the 1048...

Phidget22, Attaching to DO device

It seems the same client instance can only open a given Digital Output channel once at a time. A second attempt to attach the same device fails with a message like: PhidgetException: PhidgetException 0x34 (Device not Attached) This can happen for a number of common reasons. Be sure you are opening t...

ifKit dropping out

I have a 1203 ifKit (without the display) that has started to exhibit it an odd behavior. At times, when I turn on a digital output the ifKit just drops off line for a second, and then comes back, with all I/O reset. It is hooked up to a RaspberryPi and on the Pi I can see the the USB port disconnec...

Differentiating multiple appearances of a device

I have a 1048 temperature sensor. This Phidget has four thermocouple inputs and one onboard temp sensor. When I look for devices on the network in the onAttachHandler I get 9 responses: Serial Phidget Ch Name Ch subCh 283587 - PHIDID_1048 -- Thermocouple Input - 28 - 33 283587 - PHIDID_1048 -- Therm...

Re: DAQ1500 & 3-wire load cell

Success. The load-cells were indeed 1/2 bridges and the diagram you pointed me to was the key. Once I wired them up correctly and connected them to the DAQ1500 it just worked. well, after more than a little playing around getting the right configuration values to actually make the system useful.
