Struct ftd2xx_embedded_hal::I2c

pub struct I2c<'a> { /* fields omitted */ }

FTDI I2C interface.

This is created by calling Ft232hHal::i2c.

Implementations

impl<'a> I2c<'a>

pub fn set_stop_start_len(&mut self, start_stop_cmds: u8)

Set the length of start and stop conditions.

This is an advanced feature that most people will not need to touch. I2C start and stop conditions are generated with a number of MPSSE commands. This sets the number of MPSSE command generated for each stop and start condition. An increase in the number of MPSSE commands roughtly correlates to an increase in the duration.

Example

use ftd2xx_embedded_hal as hal;

let ftdi = hal::Ft232hHal::new()?.init_default()?;
let mut i2c = ftdi.i2c()?;
i2c.set_stop_start_len(10);
