think there are many ways to talk to senseHat:
gpioserver is build into current scratch on raspberry, supports sensors from senseHat but not setting LED individually.
See https://www.raspberrypi.org/documentati ... /README.md
scratchClient is an external python program which supports sensors and setting LED. See http://heppg.de/ikg/wordpress/?p=615
for an intro.
scratchgpio is an external tool which is maintained on http://simplesi.net/scratchgpio/
. You need to look for help there.
