code'zy' flying machine.this project is a kind of open source UAV, like crazyfile and crazyradio(http://www.bitcraze.se/).It is based on stm32 MCU and the software is base on crazyfile either .The brief difference is that i use bluetooth and android device instead of usb remoter.That is besides the flying controller,I will make a bluetooth remoter.This remoter connects with android device by bluetooth and connects with UAV by 2.4GHz radio.I will use an MSP430/STM8 MCU in remoter as protocol translater to transport message between nrf24l01 and bluetooth ttl module.
