| 47 | * There are 2 communication channels:
|
---|
| 48 | * - 1 connection with the ground station to display the values. Output for analog sticks is normalized in the range [-1, 1] (float values)
|
---|
| 49 | * - 1 connection with the target to send the controller values (and receive controller state modification requests)
