Class Ft23xxI2cBus

Represents an I2C bus implementation using the FT23xx device.

public sealed class Ft23xxI2cBus : II2cBus, IDisposable

Implements:
Meadow.Hardware.II2cBus, System.IDisposable

Properties

Gets the handle to the FT23xx device used by the I2C bus.

public IntPtr Handle { get; }

Gets or sets the bus clock speed.

public I2cBusSpeed BusSpeed { get; set; }

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public void Dispose()

Writes data from the write buffer to a peripheral on the bus, then resets the bus and reads the return data into the read buffer.

Type	Name	Description
`System.Byte`	peripheralAddress	The address of the I2C peripheral.
`System.Span<System.Byte>`	writeBuffer	The buffer to read data from.
`System.Span<System.Byte>`	readBuffer	The buffer to read returning data into.

Reads bytes from a peripheral.

public void Read(byte peripheralAddress, Span<byte> readBuffer)

Type	Name	Description
`System.Byte`	peripheralAddress	The I2C address to read.
`System.Span<System.Byte>`	readBuffer	The buffer used for data reception.

Writes a number of bytes to the bus.

public void Write(byte peripheralAddress, Span<byte> writeBuffer)

Type	Name	Description
`System.Byte`	peripheralAddress	The address of the I2C peripheral.
`System.Span<System.Byte>`	writeBuffer	The data to be written.
