Detailed Description

R/C input interface.

Definition in file drv_rc_input.h.

Macro Definition Documentation

◆ _RC_INPUT_BASE

#define _RC_INPUT_BASE 0x2b00

Definition at line 72 of file drv_rc_input.h.

◆ 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.

Definition at line 59 of file drv_rc_input.h.

◆ RC_INPUT_ENABLE_RSSI_ANALOG

#define RC_INPUT_ENABLE_RSSI_ANALOG _IOC(_RC_INPUT_BASE, 1)

Enable RSSI input via ADC.

Definition at line 75 of file drv_rc_input.h.

Referenced by PX4IO::ioctl(), and px4io_main().

◆ RC_INPUT_ENABLE_RSSI_PWM

#define RC_INPUT_ENABLE_RSSI_PWM _IOC(_RC_INPUT_BASE, 2)

Enable RSSI input via PWM signal.

Definition at line 78 of file drv_rc_input.h.

Referenced by PX4IO::ioctl(), and px4io_main().

◆ RC_INPUT_RSSI_MAX

#define RC_INPUT_RSSI_MAX 100

Maximum RSSI value.

Definition at line 64 of file drv_rc_input.h.
