Unofficial Rust bindings and wrappers for Pico Technology oscilloscope drivers

This is a meta-crate re-exporting functionality from a number of sub-crates. These crates expose common, high-performance, high-level APIs that hide the differences between the numerous Pico drivers.

Sub Crates

  • pico-common

    Common enums, structs and traits.
  • pico-sys-dynamic

    Dynamically loaded unsafe bindings for every Pico oscilloscope driver. This crate contains unsafe code.
  • pico-driver

    Common, safe wrappers implementing the PicoDriver trait. This crate contains unsafe code.
  • pico-download

    Download missing drivers on any platform.
  • pico-device

    Device abstraction over PicoDriver trait. Detects available channels and valid ranges.
  • pico-enumeration

    Cross driver device enumeration. Detects devices via USB Vendor ID and only loads the required drivers.
  • pico-streaming

    Implements continuous gap-less streaming on top of PicoDevice.


On linux pico-enumeration requires libudev-dev to be installed.


Some tests open and stream from devices and these fail if devices are not available, for example when run in CI. To run these tests, ensure that ignored tests are run too:

cargo test -- --ignored


There are a number of examples which demonstrate how the wrappers can be used

cargo run --example streaming_cli

Displays an interactive command line interface that allows selection of device, channel configuration and sample rate. Once capturing, the streaming rate is displayed along with channel values.

cargo run --example enumerate

Attempts to enumerate devices and downloads drivers which were not found in the cache location.

cargo run --example open <driver> <serial>

Loads the specified driver and attempts open the optionally specified device serial.

Usage Examples

Opening and configuring a specific ps2000 device as a PicoDevice:

use std::sync::Arc;
use pico_sdk::prelude::*;

let driver = Driver::PS2000.try_load()?;
let device = PicoDevice::try_open(&driver, Some("ABC/123"))?;

Enumerate all required Pico oscilloscope drivers, configure the first device that’s returned and stream gap-less data from it:

use std::sync::Arc;
use pico_sdk::prelude::*;

let enumerator = DeviceEnumerator::new();
// Enumerate, ignore all failures and get the first device
let enum_device = enumerator
                .expect("No device found");

let device =;

// Get a streaming device
let stream_device = device.into_streaming_device();

// Enable and configure 2 channels
stream_device.enable_channel(PicoChannel::A, PicoRange::X1_PROBE_2V, PicoCoupling::DC);
stream_device.enable_channel(PicoChannel::B, PicoRange::X1_PROBE_1V, PicoCoupling::AC);

struct StdoutHandler;

impl NewDataHandler for StdoutHandler {
    fn handle_event(&self, event: &StreamingEvent) {
        println!("Sample count: {}", event.length);

// When handler goes out of scope, the subscription is dropped
let handler = Arc::new(StdoutHandler);

// Subscribe to streaming events

// Start streaming with 1k sample rate

Enumerate all required Pico oscilloscope drivers. If a device is found but no matching driver is available, attempt to download missing drivers and try enumerating again:

use pico_sdk::prelude::*;

let enumerator = DeviceEnumerator::with_resolution(cache_resolution());

loop {
    let results = enumerator.enumerate();

    println!("{:#?}", results);

    let missing_drivers = results.missing_drivers();

    if !missing_drivers.is_empty() {
    } else {
