Crate pico_driver[−][src]
Expand description
Common, safe wrappers for Pico Technology oscilloscope drivers.
This is a sub crate that you probably don’t want to use directly. Try the top level
pico-sdk
crate which exposes everything from here.
Each Pico Technology oscilloscope relies on a native driver for communication and this driver will vary depending on the device product range. Each of these drivers has an interface which differs by either a few function arguments or a vastly differing API.

PS4000ADriver
, PS5000ADriver
, PS6000Driver
and PS6000ADriver
wrap
their corresponding loaders and expose a safe, common API by implementing
the PicoDriver
trait. These can be constructed with a Resolution
which tells the wrapper where
to resolve the dynamic library from. The LoadDriverExt
trait supplies a shortcut to load a driver
directly from the Driver
enum via try_load
and try_load_with_resolution
.
Examples
Using the raw safe bindings to open and configure the first available device:
use pico_common::{ChannelConfig, Driver, PicoChannel, PicoCoupling, PicoInfo, PicoRange}; use pico_driver::{LoadDriverExt, Resolution}; // Load the ps2000 driver library with the default resolution let driver = Driver::PS2000.try_load()?; // Load the ps4000a driver library from the applications root directory let driver = Driver::PS4000A.try_load_with_resolution(&Resolution::AppRoot)?; // Open the first device let handle = driver.open_unit(None)?; let variant = driver.get_unit_info(handle, PicoInfo::VARIANT_INFO)?; let ch_config = ChannelConfig { coupling: PicoCoupling::DC, range: PicoRange::X1_PROBE_2V, offset: 0.0 }; driver.enable_channel(handle, PicoChannel::A, &ch_config)?;
