gps

소스 코드: 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).

예제

시험을 진행할 때 GPS 신호를 속이는 목적으로 쓸만합니다(유효한 위치 정보를 가지고 있다고 시스템에 시그널을 보냄):

gps stop
gps start -f

GPS 장치 2개를 시작하려면(주 GPS 장치는 /dev/ttyS3에, 보조 GPS 장치는 /dev/ttyS4):

ina226

Source: drivers/power_monitor/ina226

Description

Driver for the INA226 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 INA226 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.

pwm_out

Source: drivers/pwm_out

Description

This module is responsible for driving the output and reading the input pins. For boards without a separate IO chip (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.

It listens on the actuator_controls topics, does the mixing and writes the PWM outputs.

The module is configured via mode_* commands. This defines which of the first N pins the driver should occupy. By using mode_pwm4 for example, pins 5 and 6 can be used by the camera trigger driver or by a PWM rangefinder driver. Alternatively, pwm_out can be started in one of the capture modes, and then drivers can register a capture callback with ioctl calls.

Implementation

By default the module runs on a work queue with a callback on the uORB actuator_controls topic.

Examples

It is typically started with:

pwm_out mode_pwm

To drive all available pins.

Capture input (rising and falling edges) and print on the console: start pwm_out in one of the capture modes:

pwm_out mode_pwm3cap1

This will enable capturing on the 4th pin. Then do:

pwm_out test

Use the pwm command for further configurations (PWM rate, levels, ...), and the mixer command to load mixer files.

Usage

pwm_out <command> [arguments...]
 Commands:
   start         Start the task (without any mode set, use any of the mode_*
                 cmds)

roboclaw

Source: drivers/roboclaw

Description

This driver communicates over UART with the Roboclaw motor driver. It performs two tasks:

  • actuator_controls_0 uORB 토픽을 기반으로 모터를 제어합니다.
  • 바퀴 인코더를 읽고 wheel_encoders uORB 토픽에 생짜 데이터를 내보냅니다

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. For Pixhawk 4, use the UART & I2C B port, which corresponds to /dev/ttyS3.

Implementation

The main loop of this module (Located in RoboClaw.cpp::task_main()) performs 2 tasks:

  1. Roboclaw가 가동중인 경우 actuator_controls_0 메세지를 기록합니다
  2. Roboclaw의 인코더 데이터를 주기적으로 읽습니다.

Because of the latency of UART, this driver does not write every single actuator_controls_0 message to the Roboclaw immediately. Instead, it is rate limited based on the parameter RBCLW_WRITE_PER.

On startup, this driver will attempt to read the status of the Roboclaw to verify that it is connected. If this fails, the driver terminates immediately.

Examples

The command to start this driver is:

$ roboclaw start

<device> is the name of the UART port. On the Pixhawk 4, this is /dev/ttyS3. <baud> is te baud rate.

All available commands are:

  • $ roboclaw start <device> <baud>
  • $ roboclaw status
  • $ roboclaw stop

Usage

roboclaw <command> [arguments...]
 Commands:

safety_button

Source: drivers/safety_button

Description

This module is responsible for the safety button. Pressing the safety button 3 times quickly will trigger a GCS pairing request.

tap_esc

Source: drivers/tap_esc

Description

This module controls the TAP_ESC hardware via UART. It listens on the actuator_controls topics, does the mixing and writes the PWM outputs.

Implementation

Currently the module is implementd as a threaded version only, meaning that it runs in its own thread instead of on the work queue.

Example

The module is typically started with: tap_esc start -d /dev/ttyS2 -n <1-8>

Usage

tap_esc <command> [arguments...]
 Commands:
   start         Start the task
     [-d <val>]  Device used to talk to ESCs
                 values: <device>

vmount

Source: modules/vmount

Description

Mount (Gimbal) control driver. It maps several different input methods (eg. RC or MAVLink) to a configured output (eg. AUX channels or MAVLink).

Documentation how to use it is on the gimbal_control page.

Implementation

Each method is implemented in its own class, and there is a common base class for inputs and outputs. They are connected via an API, defined by the ControlData data structure. This makes sure that each input method can be used with each output method and new inputs/outputs can be added with minimal effort.

Examples

Test the output by setting a fixed yaw angle (and the other axes to 0):

vmount stop
vmount test yaw 30

Usage

vmount <command> [arguments...]
 Commands:
   start

   test          Test the output: set a fixed angle for one axis (vmount must
                 not be running)
