Re: Using sparkfun photon weather shield with a Pi

Thanks again for this thorough reply - Yes, it was the ADC requirement of the Pi which is what I was wary of (I really want to use that wind direction monitor!), and what I assumed this shield solved for me. I was hopeful that I could run it from the 3.3v GPIO out on the Pi and pull data from it tha...

Re: Using sparkfun photon weather shield with a Pi

Thanks for your reply! I actually don't have a Photon, just came into posession of the board. It's what the process for connecting to the GPIO I'm confused about (found a diagram for doing so to a previous iteration of the shield, but it has a different power setup to this current version), and what...

Using sparkfun photon weather shield with a Pi

Hello all, I have this photon weather shield (https://www.sparkfun.com/products/13630) and I was hoping to be able to read the output from it on my Pi 3 (specifically the temp/humidity/pressure sensors and the input for wind direction). Has anyone got any suggestions for how to hook it to the GPIO p...

zooming in with external screen

Hi, I'd like to zoom in on one part of my Pi's desktop (one of the windows running in it) so that it fills the entire external screen, hiding the menu bar etc. Is there a native setting that can do this, or some external piece of software?

Re: Issues with dpkg/lxde after trying to upgrade

Noted, thanks. Removed debian from sources now. Will try this tomorrow and see what happens - there's some awkward programs on there it'd be a real pain to try and reinstall.

Re: Issues with dpkg/lxde after trying to upgrade

Ah. The whole reason I was updating actually was because I have a Pi 2 arriving in the morning, and knew an update was needed. I didn't realise that the update wasn't compatible with the Pi 1! So theoretically this should run fine on the 2?

Hi all, Have just run sudo apt-get update and sudo apt-get upgrade , and now I'm having some weird issues. The LXDE now goes to a black screen with just the cursor in the middle, and I can't get out of it without pulling the power. I ran upgrade again (in case there was some error I missed), and get...

Hi All, I want to create a short executable script that uses a step motor to create an audible 'knocking' pattern - so turning the motor short and sharply back and forth a few times, to drum against a surface. Would this be easier to script with Rpi GPIO or wiringPi? Or any other simple method? I ha...

Turns out there was a minor fraying inside the connector of one of the jumper cables that I didn't realised until I examined it closer. Thanks everyone, just goes to show you should always check the cables first!

Hi folks, So I'm interested in highlighting to users what information is broadcast by smartphones, particularly MAC addresses, RSSI and recent SSIDs.

Re: strange issues with automating script on login

I solved it - turns out it was user permissions in rc.local that were the trouble, preventing access to the audio hardware because the script started before the auto user login process did. If you get this error, you need to add your user (in this case pi) permission to the rc.local file alongside w...

Re: strange issues with automating script on login

Why are you using nohup? You almost certainly do not need it. Are you aware that it redirects all output to the file nohup.out? You say that "sudo ./scan.sh" works and "nohup sudo ./scan.sh &" does not. So have you tried "sudo ./scan.sh &" or "nohup sudo ....

Yeah this is what I'm not getting - when I try to run the scan.sh script (/home/pi/libOSC/scan.sh) like that from command line, it says command not found...but if I cd to the libOSC directory and then ./scan.sh, it runs fine. Why is that?

So I think this is to do with the logic of bash which I've not yet grasped yet. I have a script in /home/pi/libOSC called scan.sh, which needs sudo privileges to run correctly. It runs correctly if I cd to /libOSC and then sudo ./scan.sh So I am trying to auto run it at startup with pd-extended, and...
