Hi I am converting my software from Phidgets DC and VoltageRatioEncoder objects connected via USB hub to a VINT hub. However I now see many DataRate errors in log files. The software is using the same data rate as before (35ms for VoltageRatioEncoder). Errors dissapear around 200ms DataRate which is...
Hi I am considering HKT22 optical encoder, had a very good look on Phidgets website but wasn't sure how it integrates (or doesn't) with other Phidgets. My setup currently is stepper + controller + encoder, wanting to drive stepper to up to +-0.15mm precision. Ideally, I would like to use rotary opti...
Thanks all, very interesting suggestions. @fraser: I set the gain but it just does nothing, ie it reverts immediately back and disconnects etc. The calls to bridge are based on event call-backs (p22 API) so the minimal polling intervals are obeyed. Only one stepper is relatively close to usb cables ...
Hm, well there are no EMI changes in the setup. The entire environment is comprised of several Phidgets boards (few stepper boards and a bridge) in metal casing so I guess external interference would be minimal even if there was something to interfere. Same for power, there are no changes in other b...
Hi Fraser You are correct, the detaches are worrying. What I think happens is: 0) Bridge is attached to a linear encoder which works fine and values are within range that is usual (ie there are no spikes or out-of-range values) 1) The software is reading the encoder using VoltageRatio property of Br...
Hi I have Bridge 1046 disconnecting from USB (Using latest Phidget22 from 7 Mar 2018 and c#). I can't pin why is it disconnecting, I suspect it gets flooded with events and just decide to reset itself. When it reset itself it goes to gain 128x (I use 1x gain) and reports " OutOfRange Overrange ...
And to respond to myself, I was looking at the wrong class, I should have used VoltageRatioInput.BridgeGain property. To make things worse for me, I actually did use this just didn't look at the correct code. Must get some sleep.
Hi I can't find Phidget22 API method in VoltageInput (or anywhere else) to control Bridge 1046 gain. Anyone knows how do I set bridge gain in Phidget22? This used to be available in Phidget21 as BridgeGain property. I have a weird situation where Bridge gets overwhelmed for some reason (not sure why...
Hi I tried upgrading 2 bipolar stepper motor controllers today to firmware 102 using latest Phidgets22 control panel on windows 10. Normally this is straight forward thing to do and I have upgraded dozens of these. However I have been repeatedly getting error upgrading firmware saying the device can...
