[STM32 Drone programming from scratch] 9-2. Checking for throttle and SwA when FC booting and arming

In this video, among the safety features, when FC booting and motor arming, the position of the SwA and throttle stick is checked to prevent accidents caused by sudden rotation of the motors and a buzzer alert is implemented.
M-HIVE "STM32 Drone programming from scratch"
This is the only course about the drone embedded system development from sensor interface, the most basic feature, to PID control for the flight control.
