Introduction

With this series of learnings and tasks i want to learn and become proficient in ArduPilot development, main phases will be:

1. Toolchain & Workflow (Linux, build, debug)
2. ArduPilot Architecture (AP_HAL, libraries, scheduling)
3. Flight Dynamics + Tuning (multirotor + UGVs)
4. State Estimation (EKF3, GPS, mag, baro, rangefinder)
5. Sensors & Drivers in ArduPilot (I2C/SPI/UART/CAN)
6. MAVLink, Logs, Telemetry, Analysis
7. Custom Features / Automations (modes, failsafes, payload logic)

Toolchain & Workflow (Linux, build, debug)

The goal of this phase is:

1. Build ArduPilot from source
2. Run Copter + Rover in SITL
3. Connect with MAVProxy / QGC
4. Create a mission in simulation
5. Download and analyze a log
6. Rebuild firmware in <2 minutes
