gps

Source: drivers/gps (opens new window)

Description

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).

Implementation

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).

Examples

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

Usage

ina226

Source: drivers/power_monitor/ina226 (opens new window)

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 (opens new window)

Description

This module is responsible for driving the output 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.

On startup, the module tries to occupy all available pins for PWM/Oneshot output. It skips all pins already in use (e.g. by a camera trigger module).

Implementation

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

roboclaw

Source: drivers/roboclaw (opens new window)

Description

This driver communicates over UART with the Roboclaw motor driver (opens new window). It performs two tasks:

• actuator_controls_0 UOrb 주제를 기반으로 모터를 제어합니다.
• 휠 인코더를 읽고 wheel_encoders UOrb 주제에 원시 데이터를 게시합니다.

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 사용 가능해지면, actuator_controls_0 메시지를 Roboclaw에 작성하십시오.
2. 일정한 속도로 Roboclaw에서 인코더 데이터를 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
