ArduPilot modification, running on Arduino Pro Mini board

Here's a modification of original ArduPilot, running on Arduino Pro Mini.



I'm just posting photos for now, since there's still lots of things to do for my planes to fly. Maybe when things are… Continue

ArduPilot + Smartphone autopilot design





ArduPilot is great piece of hardware, no doubt. However it comes to its limits, mainly with limited memory, just one serial port, limited connectivity to other peripherals.

So I have idea in my mind about improved setup, which would still use ArduPilot as hardware interface board… Continue

ArduPilot installed in plane, indoor testing and simulations done





It's still freezing cold outside, so I'm playing by PC with more simulations.

My first UAV is ready to go, for now I hooked by FTDI cable to PC, and checking if everything is OK, before going out to make a real flight.…

Increasing GPS device (EM 406a) baudrate

Default baudrate of EM406a GPS device is 4800 baud. Then this baud rate dictates entire communication of serial port on ArduPilot - also those for Serial OUT (telemetry).



Here's simple way how to permanently increase baud rate of EM 406. Once done, the device will remember the baudrate, and you can increase serial speed in ArduPilot code.



1) Temporarily connect your GPS directly to FTDI… Continue

ArduPilot modification for controlling 4 servos from code

Original ArduPilot controls 2 servos (throttle/yaw) by autopilot code or from RC receiver. Other 2 servos are controlled by FMA copilot (or again manually by RC). Although there're servo IN3/4 and servo OUT 3/4 connectors on ArduPilot board, they're at present unused (actually only pass-through control from IN3/4 to OUT3/4 is connected).



Yet there's simple way to control all 4 servos from ArduPilot code, and use other two servos for interesting tasks, such as moving plane's camera… Continue

Alternative connection of GPS to ArduPilot

If you don't like too short connection cable of GPS to ArduPilot, then here's a fix. Longer cable and better connector will solve 2 problems:

- more flexible assembly into a plane

- easier program upload to board (since GPS cable must be disconnected before uploading)



Original connection:…

ArduPilot code - now for MS Visual Studio plus parsing of Google Earth KML files

ArduPilot code, modified version for use on Microsoft Visual Studio. Compatibility with Arduino studio still maintained.

Also contains parser of KML files, for importing fly paths drawn in Google Earth.



Installation instructions:

1) Download and extract ArduPilot_20090211.zip

2) Download… Continue
