## dshot
Source: [drivers/dshot](https://github.com/PX4/PX4-Autopilot/tree/main/src/drivers/dshot)
### 설명
This is the DShot output driver. It is similar to the fmu driver, and can be used as drop-in replacement
to use DShot as ESC communication protocol instead of PWM.
On startup, the module tries to occupy all available pins for DShot output.
It skips all pins already in use (e.g. by a camera trigger module).
It supports:
- DShot150, DShot300, DShot600
- telemetry via separate UART and publishing as esc_status message
- sending DShot commands via CLI
### 예
Permanently reverse motor 1:
```
dshot reverse -m 1
dshot save -m 1
```
After saving, the reversed direction will be regarded as the normal one. So to reverse again repeat the same commands.
### Usage {#dshot_usage}
```

## gps
Source: [drivers/gps](https://github.com/PX4/PX4-Autopilot/tree/main/src/drivers/gps)
### 설명
GPS driver module that handles the communication with the device and publishes the position via uORB.
It supports multiple protocols (device vendors) and by default automatically selects the correct one.
The module supports a secondary GPS device, specified via `-e` parameter. The position will be published
on the second uORB topic instance, but it's currently not used by the rest of the system (however the
data will be logged, so that it can be used for comparisons).
### 구현
There is a thread for each device polling for data. The GPS protocol classes are implemented with callbacks
so that they can be used in other projects as well (eg. QGroundControl uses them too).
### 예
Starting 2 GPS devices (the main GPS on /dev/ttyS3 and the secondary on /dev/ttyS4):
```
gps start -d /dev/ttyS3 -e /dev/ttyS4
```
Initiate warm restart of GPS device
```
gps reset warm
```

## ina220
Source: [drivers/power_monitor/ina220](https://github.com/PX4/PX4-Autopilot/tree/main/src/drivers/power_monitor/ina220)
### 설명
Driver for the INA220 power monitor.
Multiple instances of this driver can run simultaneously, if each instance has a separate bus OR I2C address.
For example, one instance can run on Bus 2, address 0x41, and one can run on Bus 2, address 0x43.
If the INA220 module is not powered, then by default, initialization of the driver will fail. To change this, use
the -f flag. If this flag is set, then if initialization fails, the driver will keep trying to initialize again
every 0.5 seconds. With this flag set, you can plug in a battery after the driver starts, and it will work. Without
this flag set, the battery must be plugged in before starting the driver.

(eg. Pixracer), it uses the main channels. On boards with an IO chip (eg. Pixhawk), it uses the AUX channels, and the
px4io driver is used for main ones.

## roboclaw
Source: [drivers/roboclaw](https://github.com/PX4/PX4-Autopilot/tree/main/src/drivers/roboclaw)
### 설명
This driver communicates over UART with the [Roboclaw motor driver](https://www.basicmicro.com/motor-controller).
It performs two tasks:
- Control the motors based on the OutputModuleInterface.
- Read the wheel encoders and publish the raw data in the `wheel_encoders` uORB topic
In order to use this driver, the Roboclaw should be put into Packet Serial mode (see the linked documentation), and
your flight controller's UART port should be connected to the Roboclaw as shown in the documentation.
The driver needs to be enabled using the parameter `RBCLW_SER_CFG`, the baudrate needs to be set correctly and
the address `RBCLW_ADDRESS` needs to match the ESC configuration.
The command to start this driver is: `$ roboclaw start <UART device> <baud rate>`

roboclaw <command> [arguments...]
Commands:
start
stop
status print status info
```

## septentrio
Source: [drivers/gnss/septentrio](https://github.com/PX4/PX4-Autopilot/tree/main/src/drivers/gnss/septentrio)
### 설명
Driver for Septentrio GNSS receivers.
It can automatically configure them and make their output available for the rest of the system.
A secondary receiver is supported for redundancy, logging and dual-receiver heading.
Septentrio receiver baud rates from 57600 to 1500000 are supported.
If others are used, the driver will use 230400 and give a warning.
### 예
Use one receiver on port `/dev/ttyS0` and automatically configure it to use baud rate 230400:
```
septentrio start -d /dev/ttyS0 -b 230400
```
Use two receivers, the primary on port `/dev/ttyS3` and the secondary on `/dev/ttyS4`,
detect baud rate automatically and preserve them:
```
septentrio start -d /dev/ttyS3 -e /dev/ttyS4
```
Perform warm reset of the receivers:
```
gps reset warm
```
### Usage {#septentrio_usage}
