I came across an open source flight controller project designed for Quadcopters called Simple Flight Controller (SFC) which is based on an MSP430 – specifically the RF2500 2.4GHz development modules. I modified the source to compile on MSPGCC and got it to say “hello world” to me but then had to shelve it due to pressing work projects.
