[Tutor] PYFTDI Library for FT232H
I am relatively new to Pyton and am trying to use a library called pyftdi which is used to establish communication with USB chips made by FTDI. I have been able to install the library and write a simple piece of code to discover my interfaces (I have two FT232H devices connected). The following code seems to work to accomplish that: #!/usr/bin/python from pyftdi.pyftdi.ftdi import * vps=[(0x0403,0x6014)] devs=Ftdi.find_all(vps) print devs However I cannot figure out what to do next. The devices in question are programmed n the FT245 Syncronous mode and I need to send a short string to one of them to start a data download and then receive straming data on the other one. I have a C program that will do this but I need to do it in Python. Any help would be gretly appreciated.

Although we do cover some common third party libraries too it's not really our purpose. You might be very lucky and find someone who knows this particular library but you will generally have better success on a support forum for the library or by writing the author directly. Failing that you could try the main Python mailing list/newsgroup. I have a C program that will do this but I need to do it in Python. If it's simply how to translate the C to Python we might be able to help. If you can post a short example of the C that you want to emulate we may be able to help with that. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
