# Firmware overview
|
||||
|
||||
## Dataflow
|
||||
|
||||
<img src="img/dataflow.svg" width=800 alt="Firmware dataflow diagram">
|
||||
|
||||
The main loop is running at 1000 Hz. All the dataflow is happening through global variables (for simplicity):
|
||||
|
||||
* `t` *(float)* — current step time, *s*.
|
||||
* `dt` *(float)* — time delta between the current and previous steps, *s*.
|
||||
* `gyro` *(Vector)* — data from the gyroscope, *rad/s*.
|
||||
* `acc` *(Vector)* — acceleration data from the accelerometer, *m/s<sup>2</sup>*.
|
||||
* `rates` *(Vector)* — filtered angular rates, *rad/s*.
|
||||
* `attitude` *(Quaternion)* — estimated attitude (orientation) of drone.
|
||||
* `controls` *(float[])* — user control inputs from the RC, normalized to [-1, 1] range.
|
||||
* `motors` *(float[])* — motor outputs, normalized to [-1, 1] range; reverse rotation is possible.
|
||||
|
||||
## Source files
|
||||
|
||||
Firmware source files are located in `flix` directory. The key files are:
|
||||
|
||||
* [`flix.ino`](../flix/flix.ino) — main entry point, Arduino sketch. Includes global variables definition and the main loop.
|
||||
* [`imu.ino`](../flix/imu.ino) — reading data from the IMU sensor (gyroscope and accelerometer), IMU calibration.
|
||||
* [`rc.ino`](../flix/rc.ino) — reading data from the RC receiver, RC calibration.
|
||||
* [`estimate.ino`](../flix/estimate.ino) — drone's attitude estimation, complementary filter.
|
||||
* [`control.ino`](../flix/control.ino) — drone's attitude and rates control, three-dimensional two-level cascade PID controller.
|
||||
* [`motors.ino`](../flix/motors.ino) — PWM motor outputs control.
|
||||
|
||||
Utility files include:
|
||||
|
||||
* [`vector.h`](../flix/vector.h), [`quaternion.h`](../flix/quaternion.h) — project's vector and quaternion libraries implementation.

# Log analysis
|
||||
|
||||
Flix quadcopter uses RAM to store flight log data. The default log capacity is 10 seconds at 100 Hz. This configuration can be adjusted in the `log.ino` file.
|
||||
|
||||
To perform log analysis, you need to download the log right after the flight without powering off the drone. Then you can use several tools to analyze the log data.
|
||||
|
||||
## Log download
|
||||
|
||||
To download the log, connect the ESP32 using USB right after the flight and run the following command:
|
||||
|
||||
```bash
|
||||
make log
|
||||
```
|
||||
|
||||
Logs are stored in `tools/log/*.csv` files.
|
||||
|
||||
## Analysis
|
||||
|
||||
### PlotJuggler
|
||||
|
||||
The recommended tool for log analysis is PlotJuggler.
|
||||
|
||||
<img src="img/plotjuggler.png" width="500">
|
||||
|
||||
1. Install PlotJuggler using the [official instructions](https://github.com/facontidavide/PlotJuggler?tab=readme-ov-file#installation).
|
||||
|
||||
2. Run PlotJuggler and drag'n'drop the downloaded log file there. Choose `t` column to be used as X axis.
|
||||
|
||||
You can open the most recent downloaded file using the command:
|
||||
|
||||
```bash
|
||||
make plot
|
||||
```
|
||||
|
||||
You can perform both log download and run PlotJuggler in one command:
|
||||
|
||||
```bash
|
||||
make log plot
|
||||
```
|
||||
|
||||
### FlightPlot
|
||||
|
||||
FlightPlot is a powerful tool for analyzing logs in [ULog format](https://docs.px4.io/main/en/dev_log/ulog_file_format.html). This format is used in PX4 and ArduPilot flight software.
|
||||
|
||||
<img src="img/flightplot.png" width="500">
|
||||
|
||||
1. [Install FlightPlot](https://github.com/PX4/FlightPlot).
|
||||
2. Flix repository contains a tool for converting CSV logs to ULog format. Build the tool using [the instructions](../tools/csv_to_ulog/README.md) and convert the log you want to analyze.
|
||||
3. Run FlightPlot and drag'n'drop the converted ULog-file there.
|
||||
|
||||
### Foxglove Studio
|
||||
|
||||
Foxglove is a tool for visualizing and analyzing robotics data with very rich functionality. It can import various formats, but mainly focuses on its own format, called [MCAP](https://mcap.dev).
|
||||
|
||||
<img src="img/foxglove.png" width="500">
|
||||
|
||||
1. Install Foxglove Studio from the [official website](https://foxglove.dev/download).
|
||||
|
||||
2. Flix repository contains a tool for converting CSV logs to MCAP format. First, install its dependencies:
|
||||
|
||||
```bash
|
||||
cd tools
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
3. Convert the log you want to analyze:
|
||||
|
||||
```bash
|
||||
csv_to_mcap.py log_file.csv
|
||||
```
|
||||
|
||||
4. Open the log in Foxglove Studio using *Open local file* command.

Flix simulator is based on [Gazebo Classic](https://classic.gazebosim.org) and consists of the following components:
|
||||
|
||||
* Physical model of the drone: [`models/flix/flix.sdf`](models/flix/flix.sdf).
|
||||
* Plugin for Gazebo: [`simulator.cpp`](simulator.cpp). The plugin is attached to the physical model. It receives stick positions from the controller, gets the data from the virtual sensors, and then passes this data to the Arduino code.
|
||||
* Arduino imitation: [`Arduino.h`](Arduino.h). This file contains partial implementation of the Arduino API, that is working within Gazebo plugin environment.

||||
|
||||
To build, go to the `<flix>/tools/csv_to_ulog` directory and run:
|
||||
|
||||
```bash
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ..

Convert a CSV file to ULog:
|
||||
|
||||
```bash
|
||||
./csv_to_ulog log_file.csv
|
||||
```
|
||||
|
||||
ULog file will be saved in the same directory.
