Re: UV4L on raspbian buster

Unfortunately, all the hints given here do not work for me. I have installed the newest buster on a RPi3 and get only a blank screen from my RPi camera. And no error message at all, so I have no idea what I am making wrong. Are there any new suggestions? My camera says uv4l --driver raspicam --auto-...

I've uploaded a version which has the motion still recording mode available so you can upgrade now and give it a try.
Thanks: I have been using the new feature without any problems until August. Great software! I appreciate the larger screen that can be monitored.

Is there a documentation for this feature?

That is great. If I understand it correctly one can use PiKrellCam to tell that a motion occurred and trigger a still picture without triggering video. This was a feature that was requested a while ago. Did I get this right? And is there a wiki or something else where we can put some more informatio...

Re: PiKrellCam: motion vector detect + OSD web interface

There's always a motion video so you can't just take stills with no video. I might look at adding that possibility. That would be great, bill! I use pikrellcam mainly for identifying who is entering an area and there videos take up lots of space but pictures have a much higher resolution (and still...

Re: [SOLVED] wlan1 (5GHz) does not come up

MrEngman has on his webpage an sh-file that I ran. This file did everything, installing the driver as well as activating it.

Unfortunately, I just realized that it is only with 2.4GHz, not 5GHz. I am sure that this is not a software issue.

Re: wlan1 (5GHz) does not come up

Thanks for your help. It DID work out of the box but after I upgraded kernel and system it stoped working. lsusb shows it:

Code: Select all

Bus 001 Device 006: ID 2001:3318 D-Link Corp. 
FHEM is just a perl package that I installed over it, very straightforward.


(Or maybe simply the dongle is not working?)

Re: MCP3201 SPI bit bang

I had to average the raw results from the microprocessor to get reliable values. Is this necessary with your approach as well? It does not seems so and this would be a great improvement.

Re: MCP3201 SPI bit bang

I am taking your code. I am still struggling which the best frequency would be. The higher the coarser the data get. 40kHz seems a reasonable choice, if the value is lower it takes too long. I am now running a longer test over night to see which numbers are best.

Re: MCP3201 SPI bit bang

Yes, I know (the voltage is 3.3). The problem is: The above code gives me constantly (around) 3.1 voltage, hence gpiozero should show (around) 0.939. But instead I see values as in the above picture which is inconsistent.
