octasonic-rs

Rust library for interacting with the Octasonic 8 x HC-SR04 breakout board over SPI.

This code has been tested on a Raspberry Pi 3 Model B running Raspian Jessie and Rust stable 1.16.0

You must enable SPI on the Raspberry Pi for this library to work! Use the Raspberry Pi Configuration utility to do this.

Examples

The blink example sends SPI commands to the octasonic board to blink the LED. This is the easiest way to verify that the board is working correctly.

cargo run --example blink

Demo

The demo example shows readings from each sensor and shows how to set various parameters on the board.

cargo run --demo

Piano

The piano example generates MIDI instructions based on sensor readings and writes them to stdout.

This output can be piped into fluidsynth to generate music.

Install fluidsynth:

sudo apt-get install fluidsynth

Compile the example using the release configuration:

cargo build --release --example piano

Run the example

./target/release/examples/piano | fluidsynth -a alsa -s -l /usr/share/sounds/sf2/FluidR3_GM.sf2
