Software

Monitoring is done through a serial connection between the host and the Arduino.

Application ardperf must be running on the host that sends statistics to the corresponding serial interface (e.g. /dev/ttyUSB0). Arduino UNO listens to the serial interface and if data is received, it displays it on the LCD screen.

Dependencies

• Python 3.10
• Arduino IDE

Installation

1. Upload sketch ardperf.ino to Arduino UNO using Arduino IDE.

2. Install ardperf.py application:

   python3 -m pip install "git+https://github.com/endygamedev/ardperf.git"

Usage

Example of running an application to send statistic to Arduino:

python3 -m ardperf \
    --device=/dev/ttyUSB0 \
    --verbose

Mandatory argument --device specifies the path to serial interface of the host.

Optional --verbose argument specifies whether to output statistics to STDOUT.
