This repository contains the software source and hardware design files for the v0 prototype of the Pufferfish ventilator. Note that this prototype version does not have a uniform or high level of documentation. We are working to prepare the software and hardware files for the v1 prototype for open-source release. The v1 prototype uses an STM32 microcontroller and a Raspberry Pi 4, while the v0 prototype uses an Arduino Due microcontroller board and a Jetson Nano. The v0 prototype software is for development purposes and supports logging sensor readings and other variables at 667 Hz (limited by the 1.5 ms cycle for reading all 8 I2C sensors currently in use).
To program the Arduino Due
- you need to make sure you have Arduino Due support in your IDE - follow instructions on https://www.arduino.cc/en/Guide/ArduinoDue
- you need to add the libraries in the arduino libraries folder - follow instructions on https://www.arduino.cc/en/guide/libraries
- make sure you use the native USB port (for both programming and running the Arduino): https://www.arduino.cc/en/uploads/Guide/DueSerialPorts.jpg
To use the software
- make sure you have installed pyserial, qtpy, pyqt5, pyqtgraph (you can install these packages with pip3 install. E.g. pip3 install qtpy --user)
- use "sudo usermod -aG $USER dialout" to have access to serial ports without sudo
- use "python3 main.py to launch the program"
