Re: Problems with some of the examples

Have you looked at ola? (http://openlighting.org)

I work in a school which has some DMX lights and an AVT DMX511 USB interface:
http://sklep.avt.pl/konwerter-usb-dmx512.html
I'm trying to figure out a way to make a Python module so pupils can write programs to control the lights for discos and theatre productions and possibly also as a strobe for Physics lessons.
So far I've downloaded libftdi1-1.2 on ubuntu 14.04 LTS on a HP laptop and some of the examples work and some don't.

ian@HP-620:~/BISC/computing/lighting/libftdi1-1.2/build/examples$ sudo ./baud_test
real baudrate used: 9600
this test should take 10.42 seconds
and took 41.0899 seconds, this is 2434 baud or factor 0.254

Do you have any ideas where I should start looking to solve these problems? I notice that there is a python directory in the source. Does this mean that some kind of wrapper already exists?

Yours

Ian
