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.

Relay(PINIO)

# GPIOs

PA4 PINIO1 OUTPUT GPIO(81) LOW //”Vxs” power switch
PB5 PINIO2 OUTPUT GPIO(82) LOW //Camera input 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 //”Vxs” power switch PINIO
RC7_OPTION 28 //Relay On/Off, Use CH7 of Transmitter to control Vxs ON/OFF
RELAY_PIN2 82 //Camera input switch PINIO
RC8_OPTION 34 //Relay2 On/Off, Use CH8 of Transmitter to control C1 or C2 input

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

F405-HDTE has INAV fw preloaded for QC

ArduPilot

Support musical tone alarm with 5V passive buzzer
Download latest ArduPilot firmware from HERE.

INAV

With INAV firmware, DSHOT can not work on S3, S5,S7 because of DMA clash, pls use ONESHOT or MULTISHOT and calibrate ESC PWM range.
Support 5V passive buzzer
Download INAV firmware 4.1.x from our website.

BetaFlight

If using 5V passive buzzer, CLI “set beeper_frequency = 2500”
MATEKF405TE target was supported since BF4.3 RC3.
set dshot_bitbang = ON when using X6 and X8 DSHOT,
You may download BF 4.3 directly from BF configurator, BF 4.2.x from our website (click “Firmwares” button at upper right corner)
Barometer SPL06-001 is not supported by Betaflight.
