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) |
