hi,
trying display value interrupt event when gpio input change state.
here python code :
problem , self isn't recognize in my_stop callback.
question :
how can update gui callback.
thanks

have tried putting them in class, this?
code: select all
tmp = datetime.datetime(2000,12,14) start = tmp.today() print str(start) print "houla" class myapp(qtgui.qmainwindow, ui_mainwindow): def __init__(self): qtgui.qmainwindow.__init__(self) ui_mainwindow.__init__(self) self.setupui(self) self.lcdnumber.display(10.1) self.label.settext("essai de texte") def closeevent(self, event): print("event") reply = qtgui.qmessagebox.question(self, 'message', "etes vous sur de vouloir quitter?", qtgui.qmessagebox.yes, qtgui.qmessagebox.no) if reply == qtgui.qmessagebox.yes: gpio.cleanup() # clean gpio on ctrl+c exit gpio.cleanup() # clean gpio on normal exit event.accept() else: event.ignore() def my_start(self, channel): #interrupt 18 tmp = datetime.datetime(2000,12,14) start = tmp.today() def my_stop(self, channel): #interrupt 24 tmp = datetime.datetime(2000,12,14) stop = tmp.today() print str(stop-start) self.label.settext(str(stop-start)) if __name__ == "__main__": app = qtgui.qapplication(sys.argv) window = myapp() gpio.add_event_detect(18, gpio.falling, callback=window.my_start, bouncetime=2000) gpio.add_event_detect(24, gpio.rising, callback=window.my_stop, bouncetime=2000) window.show() sys.exit(app.exec_()) print "houla2"
