MightyOhm GC support?

Hi,

I would like to ask if it would be possible (for you ThibmoRozier ) to add the MightyOhm geiger counter protocol to the pyradmon?

The GC reports like this:

The data is reported in comma separated value (CSV) format:
CPS, #####, CPM, #####, uSv/hr, ###.##, SLOW|FAST|INST

KR

fusebit

What is the command format to configure the Mighty Ohm? Specifically if it shows up as a COM port what do we issue to configure the device or does it spit out the serial data all the time by default. For other makes (GMC for instance) you have to enable the output and issue a request to obtain the CPM. You mentioned the format it returns but if that format can be requested on an as needed basis.

EDIT - I just looked at the source code for the Mighty Ohm. Looks like it's primarily a transmit only type of device and really doesn't have support for receiving a command from the serial port. Could be modified easily enough if you wanted.
As for if Pyradmon can work. I'll assume you could just sniff the port that was attached and look for the strings as they come through. Should be easy enough to modify.

Sorry for the late response.

Could try using the MyGeiger setting as it only listens to the serial port.
CSV format is mainly generated by the application itself. (Unless the counter has a huge EEPROM. )
Could have a look to see if it requires some magic from our side.

Double checked and indeed, they output CSV over serial..
Should be fairly simple to retrieve data though I would need a tester for this.
And not sure how it will handle CPM after 30 seconds.
So maybe better to use CPS, then do the maths for 30 seconds..

Just one year later

After having the Geiger counter and the Raspberry Pi on the shelf for a long time, I solved the issue by modifying the firmware of the AVR.
Due to the fact that I'm more familiar with the microcontroller than with Phython this was the easiest way.

Now the system is up and running again

Now I finished some mechanical work
The Raspberry Pi is mounted with stand-offs to the back of the migthyohm Geiger counter. Now the RCA jack supports the whole thing from tipping over.
The Geiger counter is powered via the simple eb.. USB adapter.

Some pictures attached, this setup should run for some time now...
