python_gmc_300e_serial

A python serial interface to a GMC 300E Plus Geiger Counter and other GQ Electronics Geiger Counters.

It is based on the specification of the Communication Protocol by GQ Electronics "GQ-RFC1201" and tries to implement Python wrapper functions for the commands presented there.

Currently, this is very limited, since I am too stupid to figure out how some of the responses are encoded.

How to Use

• Install the package pip3 install -e .
• Plug in the Geiger Counter
• Check lsusb for the new device and remember the ID, e.g. 1a86
• ls -l /dev/serial/by-id will print out something like this:

lrwxrwxrwx 1 root root 13 Jun 22 14:11 usb-1a86_USB_Serial-if00-port0 -> ../../ttyUSB0

• Remember the ../../ttyUSB0 part and navigate to /dev
• Change the owner of the serial interface to your python user: chown sebastian:sebastian /dev/ttyUSB0
• Run the code:

import  pygmc300e

geiger_counter = pygmc300e.GMC300eGeigerCounter("/dev/ttyUSB0")
print(geiger_counter.version())
