I've some other informations:
i've created a class like this
class CReader(QThread):
def start(self, ser, priority = QThread.InheritPriority):
self.ser = ser
QThread.start(self, priority)
self._isRunning = True
self.numData=0;
def run(self):
print("Enter Creader")
while True:
if self._isRunning:
try:
data = self.ser.read(self.numData)
n = self.ser.inWaiting()
if n:
data = self.ser.read(n)
print(data)
except:
errMsg = "Reader thread is terminated unexpectedly."
self.emit(SIGNAL("error(QString)"), errMsg)
else:
return
def stop(self):
self._isRunning = False
self.wait()
I've tested my class and it works well and i have no error messages.
So, i think that my problem is this line (taken from previous code)
self.emit(SIGNAL("newData(QString)"), data.decode('cp1252', 'ignore'))
i need this line to display all data received to my QT interface, so can't be removed.
I've tried to use a timer to display data every 500ms: my program crasches after 5minutes.
Can you help me?
Thanks
