LinuxFlight parts list

Making progress:

• Fixed gyro interrupt.
• Able to single with gyro ISR callback using epoll, and GPIO.  Need to merge into the flight controller loop.
• Started moving code for GPS parsing using C++/ boost ASIO

Here is the parts list:

1	4X Racerstar RS30A V2 30A Blheli_S ESC OPTO 2-4S Support Oneshot42 Multishot for FPV Racer
6	Racerstar Racing Edition 2205S BR2205S 2300KV 2-4S Brushless Motor For X210 220 QAV250 FPV Frame
1	KK260 QAV FPV Frame Kit w/ Expand Board + LED Modules & 5V 2A BEC
1	OrangePI Zero

Opted to use a OrangePI Zero over the Neo AIR.  The goal is to get something in the air and then move to using a camera OSD/OpenCV.

Still can use a USB camera for a simple test.  

Here is a trace of the flight controller loop at 8Khz.  What is interesting is the I2C poll for the baro/Mag.

LinuxFlight Progress OrangePI PC

Testing barometer(MS5611) and compass (HMC5883L) with CleanFlight configurator.  The first trial will be with the OPC, then with the new OrangePI Zero.

Things to do:

• Need to add GPIO interrupt callback to sync the gryo
•  Merge GPS parser boost asio thread. 
• Add blackbox logging
• lttng logging to validate timing

Some progress, going to order quad-frame, moters,esc, etc.  Time it is all assembly board should be ready along with firmware. 

Any questions?
