GpioPadDescriptor

Bits	Description
7-5	Controller index
4-3	Port index
2-0	Pin number

OpenSessionForDev

Takes a raw #GpioPadDescriptor and returns a #IPadSession session for it.

OpenSession

Same thing as #OpenSessionForDev except it takes a GpioPadName which is then converted to a #GpioPadDescriptor. Returns an #IPadSession session.

OpenSessionForTest

Same as #OpenSession but panics on failure.

OpenSession2

Same as #OpenSession but takes a DeviceCode instead of a GpioPadName.

IPadSession

This is "nn::gpio::IPadSession".

OpenSessionForDev

Takes an u32 port, an u16 addr, an AddressingMode (1 for 10-bit, 0 otherwise) and a SpeedMode (400000 or 100000). Returns a #II2cSession session.

OpenSession

Takes an I2cDevice and returns a #II2cSession session for it.

HasDevice

Takes an I2cDevice and returns true if the device exists or false otherwise.

HasDeviceForDev

Takes an u32 port, an u16 addr, an AddressingMode (1 for 10-bit, 0 otherwise) and a SpeedMode (400000 or 100000). Returns true if the device exists or false otherwise.
