Finding all the codes from RC output to MOTORS input

i have just started figuring out what ARDUPILOT is since ive started building a quadcopter with pixhawk. i’m trying to find the answer for this question: if i move the sticks on the RC (pitch, roll, throttle, yaw) show me in the code how does it effect and activate the motors.

could anyone help me find the correct functions? no need to explain them but it will help a bit :sweat_smile:

Have you read our dev wiki?

i will read it right now, thank you
