## UART Mapping
|
||
|
|
|
||
|
|
The UARTs are marked Rn and Tn in the above pinouts. The Rn pin is the
|
||
|
|
receive pin for UARTn. The Tn pin is the transmit pin for UARTn.
|
||
|
|
|
||
|
|
- SERIAL0 -> USB
|
||
|
|
- SERIAL1 -> USART1 (User) (DMA capable)
|
||
|
|
- SERIAL2 -> USART2 (RX tied to inverted SBUS RC input, but can be used as normal UART if :ref:`BRD_ALT_CONFIG<>` =1)
|
||
|
|
- SERIAL3 -> UART3 (GPS) (TX DMA capable)
|
||
|
|
- SERIAL4 -> UART4 (User) (TX DMA capable)
|
||
|
|
- SERIAL5 -> UART5 (DisplayPort, available on DJI air unit connector) (TX DMA capable)
|
||
|
|
- SERIAL6 -> UART6 (tied to internal wireless module, MAVLink2 telem)
|
||
|
|
|
||
|
|
|
||
|
|
## RC Input
|
||
|
|
|
||
|
|
RC input is configured on the SBUS pin (inverted and sent to UART2_RX). It supports all RC
|
||
|
|
protocols except serial protocols such as CRSF, ELRS, etc. Those devices can be connected to USART1 TX and RX, instead.
|
||
|
|
Fport can be connected to USART1 TX also, but will require an external bi-directional inverter and the ref:`SERIAL1_OPTION<SERIAL1_OPTION>' = 4 (HalfDuplex) set.
|
||
|
|
|
||
|
|
## OSD Support
|
||
|
|
|
||
|
|
The LongBowF405WING supports using its internal OSD using OSD_TYPE 1 (MAX7456 driver). External OSD support such DisplayPor is setup by default using UART5. Simultaneous use of the internal OSD and Displayport is allowed. See :ref:`common-msp-osd-overview-4.2` for more info.
|
||
|
|
|
||
|
|
|
||
|
|
## PWM Output
|
||
|
|
|
||
|
|
The LongBowF405WING supports up to 12 PWM outputs .
|
||
|
|
All outputs support DShot.
|
||
|
|
|
||
|
|
The PWM is in 5 groups:
|
||
|
|
|
||
|
|
- PWM 1,2 in group1
|
||
|
|
- PWM 3,4 in group2
|
||
|
|
- PWM 5-6 in group3
|
||
|
|
- PWM 7-9 in group4
|
||
|
|
- PWM 10-12 in group5
|
||
|
|
|
||
|
|
Channels within the same group need to use the same output rate. If
|
||
|
|
any channel in a group uses DShot then all channels in that group would need
|
||
|
|
to use DShot.
|
||
|
|
|
||
|
|
## Battery Monitoring
|
||
|
|
|
||
|
|
The board has a builting voltage and current sensor. The current
|
||
|
|
sensor can read up to 120A continuosly, 160 Amps peak. The voltage sensor can handle up to 6S
|
||
|
|
LiPo batteries.
|
||
|
|
|
||
|
|
The correct battery setting parameters are set by default and are:
|
||
|
|
|
||
|
|
- BATT_MONITOR 4
|
||
|
|
- BATT_VOLT_PIN 10
|
||
|
|
- BATT_CURR_PIN 11
|
||
|
|
- BATT_VOLT_MULT 11.0
|
||
|
|
- BATT_AMP_PERVLT 50
|
||
|
|
|
||
|
|
## Compass
|
||
|
|
|
||
|
|
The LongBowF405WING does not have a built-in compass, but you can attach an external compass using I2C on the SDA and SCL pads.
|
||
|
|
|
||
|
|
## VTX power control
|
||
|
|
|
||
|
|
GPIO 81 controls the VTX BEC output to pins marked "9V" and "Vs1". Setting a RELAY function to this pin and turning it "ON" will remove the supply from these pins.
|
||
|
|
|
||
|
|
## Camera Switch
|
||
|
|
|
||
|
|
GPIO 82 controls which camera input (CC1 or C2 is applied to the internal OSD. A RELAY function can be enabled to control the switching.
|
||
|
|
|
||
|
|
## Buzzer
|
||
|
|
|
||
|
|
An active buzzer output is provided and is controlled as GPIO 80
|
||
|
|
|
||
|
|
## Loading Firmware
|
||
|
|
|
||
|
|
Firmware for these boards can be found at https://firmware.ardupilot.org in sub-folders labeled LongBowF405WING.
|
||
|
|
|
||
|
|
Initial firmware load can be done with DFU by plugging in USB with the
|
||
|
|
boot button pressed. Then you should load the "LongBowF405WING_bl.hex"
|
||
|
|
firmware, using your favourite DFU loading tool.
|
||
|
|
|
||
|
|
Subsequently, you can update firmware with Mission Planner.
