- 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.
- ArduPilot Firmware
- INAV is expected to support H743 in 2.6.
- H743-SLIM has betaflight firmware preloaded for QC
- BetaFlight target is not on the Github, pls download BetaFlight firmware from our website.
- If you flash ArduPilot firmware via BetaFlight configurator. there is a known issue that flash process will freeze at 50% if “full chip erase” is selected. Disable full chip erase when flashing, then reset to default in Mission Planner after flashing.
- It is highly recommended to use STM32CubeProgrammer to erase MCU and upload firmware http://www.mateksys.com/?p=6905
