Re: Inquiry about delay when received from RS485 port
Dear Nicolai, Great idea. You'd only need a way to make this setting survive full reset, for example if you move the code to another Revolution Pi instance. We actually have a check in the code that throws an error on startup when latency_timer has not been set to 1. Not ideal, but at least the syst...

Re: Inquiry about delay when received from RS485 port
Dear Hydro, Not sure it is the same for you, but we have solved a similar issue reading from load cells via serial. We found we had to set /sys/bus/usb-serial/devices/ttyUSB0/latency_timer to 1 for better performance. This gets overwritten on boot, so you need some way to make that setting survive r...

Re: Remove teamviewer
Dear Joris,
Yes, easy.
For older versions of the images, this fixes a periodic crash as Teamviewer was leaking memory, regardless of use.
Kees Jan
Yes, easy.
Code: Select all
$ sudo apt remove "teamview*"
$ sudo rm /etc/apt/sources.list.d/teamviewer-revpi.list

Re: RevPi Connect SE Trouble using Wifi Modules
Dear Fandi, Frankly, I would not bother with that device. If you have to download a driver from dropbox, you have no idea what nastiness is installed alongside with it. https://laurenthinoul.com/how-to-install-tp-link-tl-wn725n-on-raspberry-pi/ Instead, google for "raspberry pi USB wifi dongle&...

Re: Can't set up WireGuard
Dear Jules. I think on Bullseye you don't need the kernel module. Can you please try the following: sudo apt install -y raspberrypi-kernel-headers wireguard You may probably even omit the raspberrypi-kernel-headers package, but not sure.

Re: Counter synchronisation
Dear Alexsf,
That I do not know, though I am curious to learn. I guess we'll have to wait what one of the Kunbus experts has to say on the topic.

Re: Counter synchronisation
Dear Alexsf,
Is it not heaps easier to just do that in software? As you the system boots, you read both counters at the same time and store that as the offset. Then each cycle you read both counters at the same time, subtract the offset and you have clean, reliable counts since boot.
