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.

ArduPilot Relay

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

# GPIOs

PD10 PINIO1 OUTPUT GPIO(81) //Vsw pad power switch
PD11 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 //Vsw 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 //Vsw 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.

Tips

ArduPilot Firmware has supported the onboard barometer DPS310 since stable Plane-4.0.6 & Copter-4.0.4
H743 is supported by INAV3.0.1 or higher.
H743-WING has betaflight firmware preloaded for QC
If you flash ArduPilot firmware onto FC via INAV/BetaFlight configurator. there is a known issue that flash process will freeze at 50% if “full chip erase” is selected. It is highly recommended to use STM32CubeProgrammer to erase MCU and upload firmware. check this blog https://www.mateksys.com/?p=6905
Crossfire support only exists in “latest” 4.1, not stable 4.0.x, if you load “latest” then Set SERIAL7_PROTOCOL = 23, RSSI_TYPE = 3
