PWM1~PWM13 are Dshot and PWM capable. However, mixing Dshot and normal PWM operation for outputs is restricted into groups, ie. enabling Dshot for an output in a group requires that ALL outputs in that group be configured and used as Dshot, rather than PWM outputs. If servo and motor are mixed in same group, make sure this group run lowest PWM frequency according to the servo specification. ie. Servo supports Max. 50Hz, ESC must run at 50Hz in this group.

RC INPUT

The Rx6 pin, which by default is mapped to a timer input, can be used for all ArduPilot supported receiver protocols, except CRSF which requires a true UART connection. However, bi-directional protocols which include telemetry, such as SRXL2 and FPort, when connected in this manner, will only provide RC without telemetry.

To allow CRSF and embedded telemetry available in Fport, CRSF, and SRXL2 receivers, the Rx6 pin can also be configured to be used as true UART RX pin for use with bi-directional systems by setting the BRD_ALT_CONFIG to “1” so it becomes the SERIAL6 port’s RX input pin.

With this option, SERIAL7_PROTOCOL must be set to “23”, and:

PPM is not supported.
SBUS/DSM/SRXL connects to the Rx6 pin, but SBUS requires that the SERIAL7_OPTIONS be set to “3”.
FPort requires connection to T6 and SERIAL7_OPTIONS be set to “7”. If Telemetry doesn’t work, try set SERIAL7_OPTIONS = 135.
CRSF also requires a Tx6 connection, in addition to Rx6, and automatically provides telemetry. Set SERIAL7_OPTIONS to “0”.
SRXL2 requires a connection to Tx6 and automatically provides telemetry. Set SERIAL7_OPTIONS to “4”.

Any UART can be used for RC system connections in ArduPilot also, and is compatible with all protocols except PPM. See Radio Control Systems for details.

ArduPilot Relay(PINIO)

Camera-1 and 9Vsw On by default
Make sure 2 cameras are set with identical video format, both PAL or both NTSC.

# GPIOs

PE4 PINIO1 OUTPUT GPIO(81) //9Vsw pad power switch
PE15 PINIO2 OUTPUT GPIO(82) //Camera switch

# RCx_OPTION: RC input option

28 Relay On/Off
34 Relay2 On/Off
35 Relay3 On/Off
36 Relay4 On/Off

e.g.

RELAY_PIN 81 //9Vsw GPIO
RC7_OPTION 28 //Relay On/Off, Use CH7 of Transmitter to switch Vsw
RELAY_PIN2 82 //Camera switch GPIO
RC8_OPTION 34 //Relay2 On/Off, Use CH8 of Transmitter to switch camera

RELAY_PIN3 81 //9Vsw GPIO
RC9_OPTION 35 //Relay3 On/Off, Use CH9 of Transmitter to switch Vsw
RELAY_PIN4 82 //Camera switch GPIO
RC10_OPTION 36 //Relay4 On/Off, Use CH10 of Transmitter to switch camera

The configured feature will be triggered when the auxiliary switch’s pwm value becomes higher than 1800. It will be deactivated when the value falls below 1200.

Check the pwm value sent from the transmitter when the switch is high and low using the Mission Planner’s Initial Setup >> Mandatory Hardware >> Radio Calibration screen. If it does not climb higher than 1800 or lower than 1200, it is best to adjust the servo end points in the transmitter.

Notes & Tips

Supported by ArduPilot latest or beta release 4.1.x or higher

New Gyro ICM-42605/42688-p has been supported by INAV 3.0.2, you might download INAV fw 3.0.2 from configurator.

ICM-42605/42688-p has not been listed in configurator 3.0.1 – configuration – Accelerometer, if you type CLI command “get acc_hardware”, ICM42605 is available.
