Relay(PINIO)
- PINIO1, PIO1 pad, Low Level by default
- PINIO2, Camera switch, C1 ON by default
# GPIOs
- PA4 PINIO1 OUTPUT GPIO(81) LOW //PIO1 pad
- PB5 PINIO2 OUTPUT GPIO(82) LOW //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 //PIO1 GPIO
- RC7_OPTION 28 //Relay On/Off, Use CH7 of Transmitter to control PIO1 Low/High Level
- RELAY_PIN2 82 //Camera switch GPIO
- RC8_OPTION 34 //Relay2 On/Off, Use CH8 of Transmitter to control high/low level on PB5 pad
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.
