# GPIOs

• PE4 PINIO1 OUTPUT GPIO(81)   //Vsw 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    //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

or

• 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.

ArduPilot

• FPort support, details here https://discuss.ardupilot.org/t/frsky-fport-support-testers-wanted/50669
• PWM 5 & 6 not working in ArduPilot firmware has been fixed in latest firmware later than Oct.30 https://github.com/ArduPilot/ardupilot/pull/12685
• External MS5611 has been supported on F765-WING with latest ArduPilot firmware, Hook up MS5611 module to I2C1(CL1,DA1) or I2C2(CL2,DA2),   set GND_PROBE_EXT = 4 for the MS5611.  GND_PRIMARY = 1 to use the external barometer as the primary

——————————

• Camera-1 and Vsw On by default.
• If using 2 cameras, both should be set with identical video format, both PAL or both NTSC.
• Rx5 is not supported for now.
• If FC board and top BEC plate are not connected via Vbat/G/Vx ,  you might solder other BEC output to FC Vx and G pad for powering up servos.

——————————

• No VB2 and CU2 definitions in INAV target
• OSD font uploading could break off in MacOS  INAV configurator, pls use Windows version.
