Stuff like that tends to be done in firmware because its all low level asm. Using spare bits for adding in functions on top of older code etc. The and-or mask is a classic, ever wonder how 'sprites' were plotted on top of backgrounds without a nasty rectangular block around them?


True true.
Yet they send the datetime in a unmasked format... but cpm in a masked manner... >.<
Confusing stuff...
But it's just a mater of accepting and going on with trying to fix it, in the end-user product. :)
//Footnote: I wish DX_MON was more interested in this field, she's a genius programmer on firmware and end-user level.. Been trying to involve her into this, but egh, too busy. :P

DO I only change the gmc class or anything else? I am going to apply this in an hour or two. I have to run out now. The Main is as you sent earlier.

Sorry... Yes indeed.
I wish there was an ability to test it on my side.. Will see if I can create a simulator for it, or something in that area.. But for now, sorry for these changes.
All I am really going to change for now is the GMC class. { class gmc(...): }

Not quite...

Serial port name configured

Serial port speed configured

Protocol configured

Device number configured

Using GMC protocol for 1 => geiger 1

No samples in queue, waiting 5 seconds => geiger 1

Initializing GMC protocol communication => geiger 1

Found GMC-compatible device, version => geiger 1: GMC-300Re 2.36

Please note data will be acquired once per 5 seconds => geiger 1

Unit shows time as => geiger 1:

Problem in getData procedure (disconnected USB device?) => geiger 1:

Hmm....
One small change, then I go to my studies, with coffee.
Please try the following.

The only change is the gmc class
class gmc(baseGeigerCommunication):

    def initCommunication(self):
        print "Initializing GMC protocol communication => geiger 1\r\n"
        # get firmware version
        self.serialPort.flushInput()
        self.serialPort.write("<GETVER>>")
        # assume that device responds within 1s
        time.sleep(1)
        response=""
        while (self.serialPort.inWaiting()>0 and self.stopwork==0):
            response = response + self.serialPort.read()
        # response=self.sendCommand("< GETVER >>")

        if len(response)>0:
            print "Found GMC-compatible device, version => geiger 1: ", response, "\r\n"
            # get serial number
            # serialnum=self.sendCommand("<GETSERIAL>>")

            print "Please note data will be acquired once per 5 seconds => geiger 1\r\n"
            # update the device time

            self.serialPort.write("<GETDATETIME>>")
            # assume that device responds within 1s

Seems we are fighting a data type issue. Perhaps if the data were considered binary can Python handle that? Bitwise logical operations are easy in assembly and C but seems this is difficult in Python. I must tell you I have little to no Python experience so I do appreciate the assistance.
