esp32-airmouse

This project aims to create a Human-Machine interface (HMI) based on an Inertial Measurement Unit (IMU). The IMU converts inertial data into movement in the computer screen that can be used to control things.

client

Here, there is the source code for the pc-side client that will listen to ESP32 data on Bluetooth, plot graphics, log data and convert data into movement.

First, clone the repository, create a virtual environment and install the dependencies:

cd esp32-airmouse/client &&
python -m venv ./ &&
source ./bin/activate &&
pip install -r ./requirements.txt

Before running any script of the client-side, if you are going to use Bluetooth, you need to bind the ESP32 MAC Address in the rfcomm0. For example, for an ESP32 with mac address 24:0A:C4:EE:A3:32, you should run:

sudo rfcomm bind 0 24:0A:C4:EE:A3:32 1

datalogger.py

This script listens to the ESP32 on bluetooth or other serial and logs the data into files. You can customize the variables in the code:

watch_time_in_seconds = 5 # How many seconds do you want to run
time_interval_in_seconds = 0.01 # How many seconds you want to wait between each measurement

After configuring, run the script:

python datalogger.py

monitor.py

This script listens to the ESP32 on bluetooth or other serial and print the output on terminal. You can customize the variables in the code:

time_interval_in_seconds = 0.01 # How many seconds you want to wait between each measurement

After configuring, run the script:

python monitor.py

animator.py

This script listens to the ESP32 on bluetooth or other serial and plot some graphics about the data.

To run the script, do:

python animated_plotter.py

src

Here we have the code that needs to be uploaded into ESP32. We use PlatformIO for this.
