Struct ftd2xx_embedded_hal::I2c [−][src]
pub struct I2c<'a, Device: FtdiCommon> { /* fields omitted */ }
Expand description
FTDI I2C interface.
This is created by calling FtHal::i2c
.
Implementations
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);
Enable faster I2C transactions by sending commands in a single write.
This is disabled by default.
Normally the I2C methods will send commands with a delay after each
slave ACK to read from the USB device.
Enabling this will send I2C commands without a delay, but slave ACKs
will only be checked at the end of each call to read
, write
, or
write_read
.
Example
use ftd2xx_embedded_hal as hal; let ftdi = hal::Ft232hHal::new()?.init_default()?; let mut i2c = ftdi.i2c()?; i2c.set_fast(true);
