ftdi-embedded-hal
This is an embedded-hal implementation for the FTDI chips that can use various drivers including libftd2xx and ftdi-rs.
This enables development of embedded device drivers without the use of a microcontroller. The FTDI devices interface with PC via USB, and provide a multi-protocol synchronous serial engine to interface with most GPIO, SPI, I2C embedded devices.
Note: This is strictly a development tool. The crate contains runtime borrow checks and explicit panics to adapt the FTDI device into the embedded-hal traits.
Quickstart
- Enable the "libftd2xx-static" feature flag to use static linking with libftd2xx driver.
- Linux users only: Add udev rules.
[dependencies.ftdi-embedded-hal]
version = "0.11"
features = ["libftd2xx-static"]
Limitations
- Limited trait support: SPI, I2C, Delay, InputPin, and OutputPin traits are implemented.
- Limited device support: FT232H, FT2232H, FT4232H.
- Limited SPI modes support: MODE0, MODE2.
Examples
SPI
Communicate with SPI devices using ftdi-rs driver:
use ftdi_embedded_hal as hal;
let device = ftdi::find_by_vid_pid(0x0403, 0x6010)
.interface(ftdi::Interface::A)
.open()?;
let hal = hal::FtHal::init_freq(device, 3_000_000)?;
let spi = hal.spi()?;
Communicate with SPI devices using libftd2xx driver:
use ftdi_embedded_hal as hal;
let device = libftd2xx::Ft2232h::with_description("Dual RS232-HS A")?;
let hal = hal::FtHal::init_freq(device, 3_000_000)?;
let spi = hal.spi()?;
I2C
Communicate with I2C devices using ftdi-rs driver:
use ftdi_embedded_hal as hal;
let device = ftdi::find_by_vid_pid(0x0403, 0x6010)
.interface(ftdi::Interface::A)
.open()?;
let hal = hal::FtHal::init_freq(device, 400_000)?;
let i2c = hal.i2c()?;
Communicate with I2C devices using libftd2xx driver:
use ftdi_embedded_hal as hal;
let device = libftd2xx::Ft232h::with_description("Single RS232-HS")?;
let hal = hal::FtHal::init_freq(device, 400_000)?;
let i2c = hal.i2c()?;
GPIO
Control GPIO pins using libftd2xx driver:
use ftdi_embedded_hal as hal;
let device = libftd2xx::Ft232h::with_description("Single RS232-HS")?;
let hal = hal::FtHal::init_default(device)?;
let gpio = hal.ad6();
Control GPIO pins using ftdi-rs driver:
use ftdi_embedded_hal as hal;
let device = ftdi::find_by_vid_pid(0x0403, 0x6010)
.interface(ftdi::Interface::A)
.open()?;
let hal = hal::FtHal::init_default(device)?;
let gpio = hal.ad6();
