[Hackrf-dev] Air relay ADS-B to BTLE: How to add UART LCD and build

Tue Sep 1 17:05:15 EDT 2015

The arm-none-eabi compiler in the packages repo is an abomination :-)
get the one from launchpad, be sure to apt-get add gcc-multilib and
put the compiler in your path, done! Bonus because it is maintained by
ARM and comes with both newlib and newlib-nano specs for really small
code size.
