The code that was distributed here was the PC application. You will need to find that source code to build it for Linux.

I'd repost it but there does not appear to be an upload from this forum. I think I still have the PC application if the original source is gone.

Is it possible to share the source for the app. I'd like to get a BeagleBone or RPi to read the GMC300. I see there is a Pi posting already but think it's setup for the standard sensor. Would like to see what this app would take to run on another platform.

Looks like you have it running! Way to go.


But take a look at your log, the rev 195 app tries to open COM2.

Radioactive@Home app rev $Rev: 195 $ for GMC-300 starting...
GetCommState failed: error 6
Unable to open port COM2GetCommState failed: error 6
GetCommState failed: error 6




it seems that now read/write
this is the file:

Good going! Yes the app appears to be much more stable. I even had the cable come out of the unit and it powered down. Re-plugged and the app properly picked up the communication. Great job guys.

Not sure if this helps but I run the app with admin privileges. I was having trouble early on and that helped. I do see you have the GMC-320 device so they may have changed the serial/usb?

Just checked and this is the differences:

Loaded this along with the latest rev of the BOINC app and working right out of the chute. No messing with anything so seems to be better on the serial port setup. I just renamed the old gmc300 app to a different name and dropped the new one in and started it up. Working like a charm.

Glad we could help! The real heavy lifting was done by TJM with testing by the rest of us. I wouldn't call it 100% solid but seems to restart easy enough for me. My problem is my machine will power off for a day or so and I'm looking to pick up a Beaglebone Black board to run the software and do all of the BOINC interface. That will likely be the next project to try.

Did you have the GMC application opened at the same time you started the Boinc client? If you did then the port will not be free and the Boinc will fail. You can check the unit is working with the COM port using the GMC application but then exit that application prior to starting boinc. Also make sure all of the boinc files are not running in the background. Ctrl-alt-del and verify that no boinc code or the GMC300 code is running. Then start it fresh and see how it does.

Go to the C:\ProgramData\BOINC\slots\0 directory and report what the errors look like. I think your very close. This version of code actually works fairly well with the GMC unit.
