Discovery F3 what this is about

This is a port of the Tau Labs software to the STM32F3 Discovery board.
Its name is 'FlyingF3'.

There is also a target 'DiscoveryF3' that is the minimal code to run but does not use the built in sensors.

Its features are:

• STM32F303 72MHz 32bit ARM cortex-m4 power with hardware fpu
• L3GD20 gyro
• LSM303 accelerometer and magnetometer
• Optional SPI MS5611 when using the appropriate shield
• FreeRTOS based flight control software
• compatible to Tau Labs
• 10 PWM inputs, 10 PWM outputs
• 2 general purpose UARTs each with selectable 3V or 5V power supply (3 additional unused)
• 1 I2C for adding external sensors (unused)
• 1 SPI for adding external sensors (unused)
• 45mm drills
