RC_INPUT0_DEVICE_PATH

#define RC_INPUT0_DEVICE_PATH   "/dev/input_rc0"

Path for the default R/C input device.

Note that on systems with more than one R/C input path (e.g. PX4FMU with PX4IO connected) there may be other devices that respond to this protocol.

Input data may be obtained by subscribing to the input_rc object, or by poll/reading from the device.
