Re: SPI Device nicht mehr verfügbar in Kernel 4.19
Vielleicht fehlt im DeviceTree der "spidev0" Slave unter dem "spi0" Master (yay inclusive terminology !) oder der spidev0 Slave ist vorhanden aber als "status=disabled" markiert. Der spidev0 Slave kommt da nicht über unser "revpi-connect" Overlay rein, sondern...

Re: Linux distro incompatibility with Azure C SDK
Hm, the package must have been temporarily missing in the "Packages" list of the Raspbian repository. I recall seeing similar one-off hickups with their repo in the past.

Re: RevPi Nodes - multiple input node becomes unavailable
Which browser did you use? The one which is pre-installed on our image (epiphany-browser) is unfortunately incompatible with the RevPi nodes. If you want to access node-red on the RevPi itself, we recommend that you install chromium-browser. However, this will occupy an additional 270 MByte on the e...

Re: Can we get higher resolution from the AIO ADC than 16 bit
Not right now I'm afraid. The 24-bit value is truncated to a 16-bit value by the AIO firmware and sent over the PiBridge to the Core/Connect, which just copies it into the process image. We'd have to extend the AIO firmware and the protocol used to communicate with the AIO to allow access to higher ...

Re: DIO Polling/Interrupts
Die müssen gepollt werden. Wir wissen dass es schon länger den Wunsch gibt, dass piControl eine Notification an den Userspace gibt, wenn sich bestimmte Werte im Prozessabbild ändern. Aber wir können leider noch keine ETA dafür nennen.

Re: Hardwarekonfiguration RevPi
Kann man die RS-485 Schnittstelle des Slave-RevPi irgendwie über den Master auslesen? Die RS-485 Schnittstelle kann lokal auf dem Slave-RevPi als /dev/ttyRS485 angesprochen werden. Mit gängigen Tools wie ser2net oder socat (beides per apt-get nachinstallierbar) kannst du sie auch über TCP dem Maste...

Re: RevPI Con CAN not activating
The PiBridge and ConBridge sockets have slightly different shapes. (The edges are different.) This is intended to prevent use of ConBridge modules on the PiBridge. You may have damaged the ConBridge plug slightly when forcing it into the PiBridge socket. Hopefully the Con CAN module wasn't damaged. ...

Re: RevPI Con CAN not activating
The piright interface should only be present on a RevPi Core. The Connect has a pileft but no piright. Do you have a RevPi Core or a Connect? The Con CAN can only be used with the Connect. If you've got a Connect, check that there's a line "dtoverlay=revpi-connect" in /boot/config.txt. The...

Re: RevPI Con CAN not activating
The Con CAN module isn't handled by piControl. Rather, you should see a device "can0" when invoking "ifconfig -a". The can0 interface is instantiated by the driver for the CAN chip (hi3110). The CAN chip is attached to the SPI bus spi0. revpi-config adds an entry "dtoverlay=...
