Hi All,
I am a beginner in python and have just started using it a couple weeks ago.
I am using python 3.4.3 on windows 7 machine together with IDLE 3.4.3 for
compiling a code.
The following steps are:
I have a program, called PyAquire, such as:
import PyAquireUi
import sys
from PySide import QtGui
import PyAquireMain
def main():
master = PyAquireMain.PyAquireMain()
app = QtGui.QApplication(sys.argv)
ex = PyAquireUi.PyAquireMainWindow(master)
sys.exit(app.exec_())
if __name__ == '__main__':
main()
which opens a new window, where by clicking RUN/STOP button, program acquires
data. The data is running in the window.
Program runs in the background, acquiring data all the time and
my task is to write a code, where I will be able
a) to connect with this program without interrupting the process
b) capture the current available data
c) and save data to excel file.
The code I have written is:
import PyAquireMain
def main():
obj = PyAquireMain.PyAquireMain()# Create instance obj
obj.saveSweepData()# call the method from PyAquireMain to save the file
if __name__ == '__main__':
main()
saveSweepData function from PyAquireMain is:
def saveSweepData(self):
fileSuffix =
QtCore.QDateTime.currentDateTime().toString('yyyy-MM-dd_hh.mm.ss')
fileType = '.csv' # was .txt
if self.ch1.yData is not None:
saveFileName = 'data' + fileSuffix + fileType
with open(os.path.join(self.settings.saveDir,saveFileName),'wb') as
f:
# f.writelines(header)
np.savetxt(f,self.ch1.yData,fmt='%d',delimiter='\n')
Therefore the question is how can I access the PyAquireMain, capture data and
save file simultaneously when other program is running in the background.
Thanks,
Patrycja
