An MPSSE Context is the high-level interface to an MPSSE FTDI interface.

Fields

device: Device

max_clock_frequency: u32

clock_frequency: u32

gpio_direction: GpioDirection

gpio_value: u8

receive_timeout: Duration

Implementations

impl Context

pub fn new(device: Device) -> Result<Self>

Create a new MPSSE Context given an FTDI device.

pub fn execute(&mut self, commands: &mut [Command<'_, '_>]) -> Result<()>

Execute a slice of commands on the target FTDI device.

pub fn gpio_get(&mut self) -> Result<u8>

Get the GPIO state on the target FTDI device.

pub fn gpio_set(&mut self, pin: u8, high: bool) -> Result<()>

Set the GPIO state of an individual pin on the FTDI device.

pub fn gpio_set_direction(&mut self, pin: u8, output: bool) -> Result<()>

Set the direction of an individual pin on the FTDI device.

pub fn set_clock_frequency(&mut self, frequency: u32) -> Result<()>

Set the clock frequency for serial opertions on the FTDI device.

pub fn invalid_command(&mut self) -> Result<()>

Send an invalid command to the FTDI device (this is typically used in a debugging context to ensure synchronization with the FTDI device).
