I am wondering what the progress with the ev3 sensors is?
They’re now pretty much fully supported. The latest BrickPi have the firmware installed and we have a guide on how to update the firmware for older BrickPi.
is the latest version the 2014 7 30?
If you update to the latest the Github repo for BrickPi Python, you’ll find a python Script in there that tests the version:
And I think you’re referring to the sd card image; the latest can be found here: http://sourceforge.net/projects/dexterindustriesraspbianflavor/files/?source=navbar
The latest is 2015.03.09 I believe.
