§device: Rc<RefCell<Context>>

Implementations§

Source§

impl UltradebugGpio

Source

pub const PIN_SPI_ZB: u8 = 4u8

Request the upstream SPI bus to tristate so ultradebug may drive the SPI bus (platforms-ultradebug only).

Source

pub const PIN_RESET_B: u8 = 5u8

Reset the chip attached to ultradebug.

Source

pub const PIN_BOOTSTRAP: u8 = 6u8

Request bootstrap mode on the chip attached to ultradebug.

Source

pub const PIN_TGT_RESET: u8 = 7u8

Reset the target system attached to ultradebug (platforms-ultradebug only).

Source

pub fn open(ultradebug: &Ultradebug) -> Result<Self>

Source

pub fn pin(&self, pinname: &str) -> Result<UltradebugGpioPin>

Source

pub fn pin_name_to_number(&self, pinname: &str) -> Result<u8>

Given an ultradebug pin name, return its pin number.
