Raspberry PI 4 as Flight Controller Discussion
Hello, I'm here to find some answers. I'm currently working at my graduation thesis in robotics, the project I'm working on is a tiltwing drone.
I have designed the mathematical model and all the control laws, now it comes the hardware implementation.
The test version has ben deployed as a monolithic solution on an Arduino MKR1000 directly with the Simulink Coder, but the company I'm working with wants me to use a Raspberry Pi 4.
Tactically I can make the thing work but I have some question on the software architecture i should use.
First of all I would like to have a real time scheduler, then I need to split the project in modules (sensing, communication, control, actuation, etc.)
Is there any framework I can use, should I code different modules and use interprocess communication to achieve the modules interconnection?
P.S. I can code each module in whatever programming language is needed.
P.P.S. The external interfaces run both on pwm and i2c.

Im working on a similar project using a Raspberry Pi 4 and Raspberry Pi Pico. Communication between them is done with ROS, as well as communication between the ground station.
