Hi I'm newbie here.
Wondering if the Mavlink mission planner software is open source and what it was written in for Windows.
I have a daft idea about porting it to run on an embedded linux system. Running the linux system in the air - controllable from the ground so I can develop a hi res transparent OSD for the airborne linux system.
The other things I'd need would be good documentation for the Mavlink serial protocol or how the serial data stream is organised from the OSD/Modem port on the IMU and or the Adrupilot's USB port. I'd also need to know if their is any way to access raw RC PWM values via these interfaces. My very fledgling idea is to use three spare RC channels to simulate a mouse to control the linux system from the ground. Two axis (left right, up down) and mouse down signal and transmit the linux systems display to the ground using a bog standard video link. The hardware I have in mind has a composite output and good graphics capabilities. Its also small (slightly larger than a credit card) with low power consumption.
Any thoughts or suggestion about the idea?
Where can I get hold of a detailed description of the Adrupilot serial protocols? Without them I cant make much of a start - I cant even write the code for the linux system from scratch without this documentation.
Any comments? Good bad or indifferent?
