Re: Digital Out Pins briefly switch to HI when booting
I will have another look. At the moment I'm not able to reproduce a measureable glitch on power on. Which kind of relais are you using?

Re: Digital Out Pins briefly switch to HI when booting
Hi
Could you please test if the following fixes the problem for you?
1. Download the attached archive and extract it
2. Copy the file to your revpi as `/boot/dt-blob.bin
3. Reboot

Re: How to unplug individual wire of PCB connectors
If you're using ferrules (depending on the crimp pattern) it can be sometimes helpful to twist a little while pulling.

Re: RevPi Connect: Zugriff über 2 Netzwerkkarten
Hi Christian, wenn du ohne extra Routen aus dem einem Netz auf einen bestimmten Port (z.B. vom Webinterface) eines Gerätes im Sensornetz zugreifen willst, würde ich mit Portweiterleitungen arbeiten. So aus dem Kopf: iptables -t nat -A PREROUTING -p tcp --dport 8080 -j DNAT --to-destination 192.168.0...

Re: AIO missing decimal point
The value in process image is of type integer. Multiplier and Divisor are applied to the same integer feld, thus no decimals If you want to have a float value, I suggest to do the processing in your application.

Re: webpage password not working
The above posted /boot/config.txt gave it away: The dtoverlay=revpi-core is missing, so the device did not know which pins to connect to what. Thus nothing really will work (eg. piSerial which relies on the crypto chip). The overlay is usualy set during factory reset which you might omitted with the...
