dshot

Source: drivers/dshot

Description

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, DShot1200
• telemetry via separate UART and publishing as esc_status message
• sending DShot commands via CLI

Examples

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.

gps

Source: drivers/gps

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

ina220

Source: drivers/power_monitor/ina220

Description

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.

Description

This is a PCA9685 PWM output driver.

It runs on I2C workqueue which is asynchronous with FC control loop, fetching the latest mixing result and write them to PCA9685 at its scheduling ticks.

It can do full 12bits output as duty-cycle mode, while also able to output precious pulse width that can be accepted by most ESCs and servos.

roboclaw

Source: drivers/roboclaw

Description

This driver communicates over UART with the Roboclaw motor driver. 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>

Usage

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

   stop

septentrio

Source: drivers/gnss/septentrio

Description

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.

Examples

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:
