[−][src]Crate buspirate

Bus Pirate client library

This library implements the Bus Pirate binary protocol, allowing Rust programs to interact with a Bus Pirate and in turn to interact with SPI, I2C, UART, etc devices. The implemented protocol is that of the Bus Pirate v3.6.

The library API uses types to ensure safe switching between different Bus Pirate modes and to provide functions relating only to the current mode. At initialization, the bus pirate is assumed to be in its normal terminal mode, and so the first step implemented by this library is to switch into binary mode. After that, the caller may transition into other binary modes as desired.

The entry point is BusPirate::new, which takes (and consumes) a serial writer and a serial reader as defined by embedded_hal::serial. If you are running on a general computing platform then you can use serial_embedded_hal to connect with a serial port provided by your operating system:

let port = Serial::new(
    "/dev/ttyUSB0",
    &PortSettings {
        baud_rate: serial_embedded_hal::BaudRate::Baud115200,
        char_size: serial_embedded_hal::CharSize::Bits8,
        parity: serial_embedded_hal::Parity::ParityNone,
        stop_bits: serial_embedded_hal::StopBits::Stop1,
        flow_control: serial_embedded_hal::FlowControl::FlowNone,
    },
)?;
let (tx, rx) = port.split();
let bp = BusPirate::new(tx, rx);

A BusPirate object represents a Bus Pirate in normal terminal mode, not yet configured to speak a binary protocol. Method init can then transition into "binary bit-bang" mode, yielding a bitbang::BitBang object:

let bb = bp.init()?;

As well as offering direct control over the Bus Pirate's pins, bit-bang mode is also a gateway into the other more specialized protocol modes. For example, SPI mode:

let spi = bp.to_spi()?;

Modules

bitbang	Module `bigbang` contains the API for "binary bit-bang" mode.
peripherals	Module `peripherals` represents the general (mode-agnostic) peripherals on a Bus Pirate module.
spi	Module `spi` contains the API for SPI mode.

Structs

BusPirate

BusPirate represents a Bus Pirate device in its normal terminal mode, not yet initialized into any binary mode.
