Update: I found a bug in my app that was causing a loop to run as fast as it could and therefore consuming most of the CPU time. Since I've corrected this bug, I've not seen this problem. There may still be some bug or vulnerability in some part of the system, but for now I am avoiding it.

I'm running a Python3 program on the RevPi Core3. After running for hours, my program apparently stops running, and the following is printed to the console (via SSH). I see similar content in kernel.log. I updated my system using apt-get update then upgrade, but this didn't help. I have no idea how ...

I suspect the answer is no since OPC DA relies on Windows COM/DCOM technology and this is a Linux system. There are other flavors of OPC (OPC XML DA and OPC UA) that are capable of running on non-Windows systems.

I wanted to reinstall the OS to have a clean system. I followed the documentation for installing Jessie , and everything went as expected (after I upgraded from Win7 to Win10). I am able to log in to the web interface and pictory with the credentials provided on the sticker on the RevPi Core 3. Howe...

I wasn't able to find the git repository at that URL, or in GitHub using the search tool. Could somebody please clarify the location of this tool?

Thanks,

Thanks for your prompt reply. I am looking for a system watchdog that will turn off the digital outputs if my app crashes. It looks like the RevPi Connect is a new CPU option, right? I didn't see it in the Shop section of the web site, so I'm guessing it's still under development? I did find a Quick...

Hello, According to the RevPi documentation, the DIO module uses a watchdog which turns off the digital outputs after a short timeout after the last update from the CPU. To test this, I wrote this simple Python 3 program which toggles a digital output on and off, then leaves it on when the program e...

Thank you for your reply. I'm not sure why, but this issue seemed to resolve itself. So it looks like there was no hardware damage.

For some reason I can no longer communicate with my RevPi Core 3 after connecting a USB-serial converter device and rebooting. I can't connect with SSH, nor with WinSCP, and it doesn't respond to ping. I'm using a DHCP reservation so I'm certain of the IP address. Is there any hardware reason for th...

This post is to document a problem I ran into as well as the solution I found. I'm running a setup with these devices: (wepi) pi@RevPi6892:~ $ piTest -d Found 3 devices: Address: 0 module type: 95 (0x5f) RevPi Core V1.2 Module is present input offset: 0 length: 6 output offset: 6 length: 5 Address: ...
