GpioPadDescriptor

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

OpenSessionForDev

Takes a raw #GpioPadDescriptor and returns an #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 and an u32 DeviceUnk.

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 an #II2cSession session.

OpenSession

Takes an I2cDevice and returns an #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.

OpenSession2

Same as OpenSession but takes a DeviceCode instead of a I2cDevice.

II2cSession

This is "nn::i2c::ISession".

sasbus

This is "nn::sasbus::IManager".

This was added with [3.0.0+].

Cmd Name
0 OpenSession

OpenSession

Takes an u32 that must be 0 and returns an ISession.

This opens a session for communicating over SPI4. While code exists to support both SPI1 and SPI4 communication, SPI4 is currently hardcoded as the only available interface.

ISession

This is "nn::sasbus::ISession".

Cmd Name
0 #Write
1 #Read
2 #StartPeriodicReceiveMode
3 #StopPeriodicReceiveMode

Write

Takes a type-0x21 input buffer and an u8 SpiCommand. No output.

Read

Takes a type-0x22 output buffer and an u8 SpiCommand. No output.

StartPeriodicReceiveMode

Takes an u8 SpiCommand (padded to u32), an u32, two u64s and a copy handle. No output.

StopPeriodicReceiveMode

No input/output.
