Hi, Mastiff!

Still going strong, I see? We have discussed Girder previously, I think, you are Norwegian too, right?

I have the exact same problem and made a thread on this yesterday! So you might want to follow "Raspberry 3 Buster can't find 0/16/16". Strange thing is I got an email today saying somehow has posted a reply, but I can't see any...

I also have a powered USB hub, the phidget works fine when connected to a laptop, but the Raspberry can't connect.

Best regards,

Knut

Hi, Knut! Yep, Mandal calling. I see in my archive that we were both using this 0/16/16 board with Girder in 2008! :lol: And I'll follow it. I have almost given up getting this to work, but if you can manage, then I may be able to use your method, so thanks for the heads up! :mrgreen:

Hi!

I finally got my Raspberry Pi model B v1.2 working with the old 0/16/16 Phidget board. The problem was the "addressing" (see: https://www.phidgets.com/docs/Addressing_Phidgets) of the board in my python code. I had a call: testOut.setHubPort(1) (copied from some example). This seems to be valid only for the new VINT type boards.

As soon as I removed that, the Pi found the Phidget nicely, also without external power supply.

I couldn't quite decipher what happens in your code, but I'd bet the problem is something similar.

Good luck!

Hi,

I actually recently fixed this issue for old 1012s on Linux. Releasing new Phidget22 now.

Great, I'll try that in the weekend and see if it helps my issue too! Which is probably the same thing. :mrgreen:

Well, it may help, but I have done something wrong somewhere. Because I get
libphidget22extra.so.0: cannot open shared object file: No such file or directory
Here are the commands I used:

Code: Select all

cd libphidget22-1.6.20201117
./configure && make && sudo make install
cd /home/pi/Phidget-biblioteker/libphidget22extra-1.6.20201117
./configure && make && sudo make install
cd /home/pi/Phidget-biblioteker/phidget22networkserver-1.6.20201117
./configure && make && sudo make install
I'm not sure if it worked for the extra lib because I got this whe I did make:

Code: Select all

make
make: Nothing to be done for 'all'.
The problem seems to be the file ld.so.conf. I tried to add to path:

Code: Select all

sudo echo /usr/local/lib >> /etc/ld.so.conf && sudo ldconfig
bash: /etc/ld.so.conf: No access
Help would be appreciated, I'm totally confused...

I went back to my previous backup to see what I had done differently, and that was a lot... :mrgreen: So now I used this:

Code: Select all

wget -qO- http://www.phidgets.com/gpgkey/pubring.gpg | sudo apt-key add - && sudo bash -c "echo 'deb http://www.phidgets.com/debian stretch main' > /etc/apt/sources.list.d/phidgets.list"
sudo apt-get update
sudo apt-get install libphidget22
npm install node-red-contrib-phidget22
sudo apt-get install phidget22networkserver -y
sudo apt-get install phidget22admin -y
sudo mousepad /lib/systemd/system/phidgetsserver.service
sudo chmod 644 /lib/systemd/system/phidgetsserver.service
sudo systemctl enable /lib/systemd/system/phidgetsserver.service
It got me further, but not all the way. Is it possible that the respositorys aren't updatede and I need to do something manually?

Edit: It's alive! (Picture me as Gene Wilder's "Fronkensteen" shouting...) I have the Hello world example working, it says "Hello to Device PhidgetInterfaceKit 0/16/16, Serial Number: 15593" 32 times, which is one per input and one per output! :mrgreen: So now I have hope again. If I could only get the server working, so I can use it by Node-RED I would be a happy camper!

I get this string on restart of Node-RED (after a reboot and an attempt to open port 2, which gave me "Unsupported message topic")

Code: Select all

Attempting to Connect to Server (127.0.0.1:5661)
Attempting to Open DigitalOutput (SN:15593, Ch:2)
Connect Success (127.0.0.1:5661)
DigitalOutput Opened (SN:15593, Ch:2)
setLEDForwardVoltage (in onAttach) not supported
setLEDCurrentLimit (in onAttach) not supported
Open failed:PhidgetError: Open timed out
This is when using the Node-RED node, and injecting into a Digital Output node, with the values:
LED Forward Voltage: volts_1_7
LED Current Limit: 0.02
Channel: 2 (I assume this is the port to open, but I'm not sure)
Serial #: 15593
Using a VINT Port in DigitalOutput mode? Tried both on and off

Also, I can't get to phidget22admin on the Pi. If I use "sudo phidget22admin -s" it says "bash: could not find command phidget22admin" (well, that's translated from Norweigan, so it may not be word for word what it would say in English). Is there something I have forgotten to install? I know the server runs, since I can connect to it.

Hi,

Maybe you need to run /usr/local/bin/phidget22admin if /usr/local/bin isn't on your default path? Or, just run it directly from the source folder where it's built.

I'm not familiar with Node-RED - where is this module published? Can you see any errors in the network server logfile? Make sure that you are using the newest version of the Phidget Node.js library.

Thanks! I didn't build, as I show above I used the apt-get-install, and it isn't under /usr/local/bin. Which package should the phidget22admin be under?

As for the log there's nothing there. Only "Logging enabled". The node for Node-RED is on the regular Node-RED collection, and it's made by the Phidgets company, @mparadis announced it in January:

The network server log is here: /var/log/phidget22networkserver.log

phidget22admin from a package install should be in /usb/bin - did it install without errors?
