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.
- Enable the "libftd2xx-static" feature flag to use static linking with libftd2xx driver.
- Linux users only: Add udev rules.
