Testing development code on a flying platform is always risky, one small bug in the code could cause your beloved airframe go straight into the bin. To avoid that, always check your code stability in simulation. And the PX4 Software In the Loop (SIL) simulation is the perfect solution. SIL uses your computer hardware to

If you have done Ardupilot or Arduino source code development, the first thing you do when you clone source code from Github is probably looking for the main function. This is exactly what I did. I spent about 2 weeks looking for a main function, hoping to stumble across something that initializes everything, execute commands

Being able to connect to PX4 via Serial is essential for development. It allows you to run individual apps in PX4 and it provides a straight forward interface for debugging. I have successfully connected to a HK Pilot 32 using a FTDI breakout adapter in Ubuntu, and here is how I did it. A quick

The best development environment for PX4 is using Eclipse as IDE in Ubuntu. There are also many other ways to do it. I have included in this log what is working for me and how to do it. A quick summary: Install PX4 toolchain Install ninja build system (optional) Clone PX4 source code from Github

The first thing to do before more in-depth research is to actually use PX4 autopilot to fly something. This is a relatively straight forward process once you have a multicopter that is healthy and ready for the sky. Here is a step by step guide on how to flash px4 firmware onto your autopilot hardware
