//! # FTDI Example
//!
//! This example uses a FT232H USB to SPI device to develop the drivers
//! without the use of a microcontroller.
//!
//! One-time device setup instructions can be found in the [libftd2xx crate].
//!
//! With the [adafruit FT232H breakout] create the following connections:
//!
//! * Connect SCK to D0
//! * Connect MOSI to D1
//! * Connect MISO to D2
//! * Connect CS to D3
//! * Connect Vdd to 3.3V or 5V
//! * Connect Vss to GND
//!
//! Run the example with `cargo run --example ftdi`.
