GQ Geiger-Müller counter (GMC) CPM/CPS data feed

Forked from https://sourceforge.net/p/gqgmc/code/ci/master/tree/

Changes made

Updated make configs to build gqgmc driver only, compatible with Raspberry Pi (CPUSIZE to mbe32).

With main running a loop, printing a ISO-8601 timestamp and requested datapoint line, every second.

Commands

cpm for Counts Per Minute (default).

cps for Counts Per Second.

Usage

./bin/gqgmc <usb-port-device-name> <command>

Install 51-gqgmc.rules at /etc/udev/rules.d (configured for GMC-300E Plus) to map /dev/gqgmc otherwise provide the correct tty when calling command, i.e. /dev/ttyUSB1

Default

./bin/gqgmc [/dev/gqgmc] [cpm]

Testing

GQ GMC-300E Plus

UI

Work in progress: Next.js with D3

INSTALLATION INSTRUCTIONS

1. Download the code from sourceforge into a directory of your choice. This will be referred to as your root directory.

2. The following list of files need to be downloaded. Obtain them from the gqgmc folder.

   Makefile Defines.mk Patterns.mk Targets.mk gqgmc.cc gqgmc.hh main.cc main_gui.cc plotter.hh plotter.cc

   51-gqgmc.rules

3. Create the following subdirectories of your root directory: bin libs obj

   For example, "mkdir bin", "mkdir libs", "mkdir obj".

4. Edit Defines.mk and change the definition of BASE to the path of your root directory. If you will be compiling for 32-bit Linux, change the definition of CPUSIZE from "-m64" to "-m32" in Defines.mk.

5. From the command line, you should be able to build the 'gqgmc_gui' and 'gqgmc' executables which if the build is successful will be put into bin subdirectory. Try "make all" as the build command.

6a. Copy the 51-gqgmc.rules file to the /etc/udev/rules.d directory and force the reload of udev rules:

sudo cp ./51-gqgmc.rules /etc/udev/rules.d/51-gqgmc.rules
sudo udevadm control --reload-rules

Disconnect the GQ GMC-300 from the computer and then reconnect.
Verify that there exists a /dev/gqgmc in the /dev directory with
read/write permission for all users.

ls -la /dev/gqgmc

6b. With the GQ geiger counter connected to your PC via USB and turned on, start either bin/gqgmc or bin/gqgmc_gui from a console command line. The USB device name must be supplied from the command line, e.g.,

bin/gqgmc /dev/gqgmc
bin/gqgmc_gui /dev/gqgmc

The code expects the GQ GMC USB device name to be /dev/gqgmc. This
device name was created at step 6a.

7. The following is a list of prerequisites for successful compilation:

   a. Ubuntu Linux 11.10, 12.04 or 14.04 b. GNU g++ 4.6.x or more recent compiler installed c. Qt4 Software Development Kit (SDK) installed or Qt Creator installed (required only for GUI)
