Enum libftd2xx::ClockBitsIn

}

Modes for clocking data bits into the FTDI device.

This is an argument to the clock_bits_in method.

Variants

MsbPos = 34

Positive clock edge MSB first.

The data will be shifted up so that the first bit in may not be in bit 7 but from 6 downwards depending on the number of bits to shift (i.e. a length of 1 bit will have the data bit sampled in bit 0 of the byte sent back to the PC).

The data will be sampled on the rising edge of the CLK pin.

MsbNeg = 38

Negative clock edge MSB first.

The data will be shifted up so that the first bit in may not be in bit 7 but from 6 downwards depending on the number of bits to shift (i.e. a length of 1 bit will have the data bit sampled in bit 0 of the byte sent back to the PC).

The data will be sampled on the falling edge of the CLK pin.

LsbPos = 42

Positive clock edge LSB first.

The data will be shifted down so that the first bit in may not be in bit 0 but from 1 upwards depending on the number of bits to shift (i.e. a length of 1 bit will have the data bit sampled in bit 7 of the byte sent back to the PC).

The data will be sampled on the rising edge of the CLK pin.

LsbNeg = 46

Negative clock edge LSB first.

The data will be shifted down so that the first bit in may not be in bit 0 but from 1 upwards depending on the number of bits to shift (i.e. a length of 1 bit will have the data bit sampled in bit 7 of the byte sent back to the PC).

The data will be sampled on the falling edge of the CLK pin.

Trait Implementations

impl Clone for ClockBitsIn

fn clone(&self) -> ClockBitsIn

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClockBitsIn

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for ClockBitsIn

fn eq(&self, other: &ClockBitsIn) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
