Thanks for reply The script flashes the light in a repeating sequence, that is why it continues to run in background until stopped For the simple light functions like all on, or all off I have put the code itself in the button event, but for the scripts which loop I thought best way was to call them...

Hi I have a python script which runs a web ui for my robot, I have added a button to this ui from which I want to turn on some lights basically. So on the onclick event I am calling the other python script and it runs fine But I want another button to turn lights off and I can't work out how to then...

I know my last post here was 5 years ago but just wanted to finish the discussion to say I created my Robot (well actually it is a constantly evolving build!) and more details can be found here = http://pi-robot.co.uk/

Thanks, I'll take a look at your suggestions - much appreciated

Hi Hoping for some advice/help here I have built a robot which uses the Picoborg Reverse motor controller and I can use example python scrips from PiBorg to view camera output and move the robot, I can also use another example script to view values of the Ultraborg ultrasonic sensors I would like to...

Thanks, changed values for trail and now looks cool

Probably a much cleaner way of writing the code, but this seems to achieve what I wanted - if anyone has ideas on improvement let me know as always keen to learn more from time import sleep import apa ledstrip = apa.Apa(8) delay = 0.13 try: while True: ledstrip.led_set(0, 9, 0, 0, 255) ledstrip.led_...

That was just simply a copy/paste from manual showing example code for those lights, I fully understand indentation etc for python - that code was only posted as an example, it is not the code I am using, hence question

Hi

I have several rtl8191su wireless usb adapters which I had used fine in the past with my Pi's

But for some reason they are not detected under Raspbian Buster and I can't get them working

Any ideas or help would be much appreciated

Thank you

I have a Straight-8 LED from https://rasp.io/inspiring/ I would like to make them flash in a similar way to the lights on front of KITT (Knight Rider) e.g. https://www.youtube.com/watch?v=WxE2xWZNfOc I am new to Python so hoping someone might have done similar or can advise how to? An example piece ...

You can either put a number in GMTOffset or you can put in a time zone string (e.g. Europe/London) I doubt whether the scheduler part would affect the filenames though, more just when scheduler actions happen. What time zone are you in? A 1 hour difference sounds like a daylight savings offset. My ...

Have you set the raspberry time zone correctly to match your locale? sudo raspi-config You should also put the time zone in the Scheduler settings if you want timing in there to be consistent. Time zone is set correctly Where in the scheduler settings do I put it - can only see latituide, longitude...

Hi Can anyone advise on how to fix this problem: The time showing on the annotation / overlay on the preview is the correct time But the filename/timestamp of the captured files is an hour out Checked everywhere I can think (not used to linux, as use Windows for most things) but all seems okay, so n...

Have you tried adjusting the capture timeout in the latest version. In particular setting the timeout to 0 to disable it? The reason for checking this is because you said the previous software did not suffer the problem reported and adding the timeout was the only change. Thank you very much for yo...

The difference was that raspimjpeg had an extra timeout built in so that if it didn't get a call back from the camera within 5 seconds then it would timeout. Previously it hung up altogether if callbacks stopped. I don't know why your system is sensitive to that. What I have done is add a parameter...

Tried updating to latest version and had exact same issues as reported before and getting this error as below:- "mmal: mmal_vc_component_enable: failed to enable component: ENOSPC" Replaced raspimjpeg as above instructions back to older version (Jan 10) and now okay again - whatever has b...

To revert the raspimjpeg back to an earlier one 1) First get the earlier one. There are different ways of doing this my preferred method is a) Browse to repository and view bin folder b) Goto history and select a data (e.g. Jan 10) c) View Browse Repository at this date d) Click raspimjpeg, View Ra...

I suspect that there is some instability in your camera connection that is triggering this. Typically it is when the power supply or the USB cable is not providing a stable voltage to the Pi. In particular the USB cable needs to be low resistance or there can be a significant voltage drop along it....

Hi since updating from 6.0.25 to 6.0.28 I seem to be having a lot of problems - mainly it is losing connection to camera and I have to keep rebooting - before upgrading it would run for days at a time, but since upgrade I am lucky if I get a few hours Log below:- {2016/02/17 11:42:50} send smd 9 [20...

used wing nuts on top so can remove lid easily if need access to GPIO etc - only probably whilst playing about, once in use will replace them with dome nuts like rest of it

I couldn't find a case to quite fit my needs off the shelf - so built my own using MakerBeam - just wanted to post here about it as it is a great product and really handy for making custom cases to fit your needs http://www.pi-robot.co.uk/case/raspberry-pi-cases/ http://www.makerbeam.com/makerbeam/ ...
