编译固件
To build PX4 for this target:
sh
make radiolink_PIX6_default
Installing PX4 Firmware
The firmware can be installed in any of the normal ways:
Build and upload the source
shmake radiolink_PIX6_default upload
Load the firmware using QGroundControl. You can use either pre-built firmware or your own custom firmware.
INFO
At time of writing the only pre-built software is
PX4 main
(see Installing PX4 Main, Beta or Custom Firmware). Release builds will be supported for PX4 v1.17 and later.
:::
PX4 配置
In addition to the basic configuration, the following parameters are important:
参数 | 设置 |
---|---|
SYS_HAS_MAG | This should be disabled since the board does not have an internal mag. You can enable it if you attach an external mag. |
Powering the PIX6
The PIX6 has 2 dedicated power monitor ports, each with a 6 pin connector. One is the Analog power monitor (POWER1
), and the others is the I2C power monitor (POWER2
).
The power module that comes with the flight controller with a wide voltage input range of 2-12S (7.4-50.4V), a maximum detection current of 90A (single ESC maximum detection current is 22.5A), a BEC output voltage of 5.3±0.2V, and a BEC output current of 2A.
The PIX6 also supports power modules from other manufacturers, such as holybro_pm02d.
Recommended Accessories
GPS Modules
Radiolink manufactures a variety of high-performance GPS,Dual Anti-interference Technology Worry-free of UAV High-power Image Transmission, High-Voltage Lines, or Other Strong Signal Interference.

USART2 | /dev/ttyS1 | TELEM1 (flow control) |
USART3 | /dev/ttyS2 | TELEM2 (flow control) |
UART4 | /dev/ttyS3 | GPS2 |
UART7 | /dev/ttyS4 | Debug Console |
UART8 | /dev/ttyS5 | PX4IO |
Analog inputs
The Radiolink PIX6 has 3 analog inputs, one 6V tolerant and two 3.3V tolerant.
- ADC Pin12 -> ADC 6.6V Sense
- ADC Pin4 -> ADC IN1 3.3V Sense
- ADC Pin13 -> ADC IN2 3.3V Sense
遥控器
A Radio Control (RC) system is required if you want to manually control your vehicle (PX4 does not require a radio system for autonomous flight modes).
You will need to select a compatible transmitter/receiver and then bind them so that they communicate (read the instructions that come with your specific transmitter/receiver).
- Spektrum/DSM receivers connect to the DSM/SBUS RC input.
- PPM or SBUS receivers connect to the RC IN input port.
- CRSF receiver must be wired to a spare port (UART) on the Flight Controller. Then you can bind the transmitter and receiver together.
CRSF Parameter Configuration
Find and set the following parameters:
Set RC_CRSF_PRT_CFG to the port that is connected to the CRSF receiver (such as
TELEM1
).This configures the serial port to use the CRSF protocol. Note that some serial ports may already have a default serial port mapping or default MAVLink serial port mapping that you will have to un-map before you can assign the port to CRSF. For example, if you want to use
TELEM1
orTELEM2
you first need to modify MAV_0_CONFIG or MAV_1_CONFIG to stop setting those ports.There is no need to set the baud rate for the port, as this is configured by the driver.
Enable RC_CRSF_TEL_EN to activate Crossfire telemetry.
For more information about selecting a radio system, receiver compatibility, and binding your transmitter/receiver pair, see: Remote Control Transmitters & Receivers.
