You can run python scripts directly from Creator. You just need to add the following in the post-build option:
If the python script needs a COM Port input, you will need to import the win32com.client as follows:
pp = win32com.client.Dispatch("<Pass ProgID here>")
#example usage: pp = win32com.client.Dispatch("PSoCProgrammerCOM.PSoCProgrammerCOM_Object")
In case you have many scripts to run, you can create a batch file with sequence of commands. Just ensure your python script terminates uses sys.exit() to ensure control is passed back. In the post build command, just specify the command as <filename>.bat.
I got it working an easier way, but thanks!
