getSpeed
Gets the current clock speed of SPI communication.
func getSpeed() -> Int Returns
The current clock speed.
Gets the current clock speed of SPI communication.
func getSpeed() -> Int The current clock speed.
import SwiftIOThe SwiftIO library allows you to access and control the hardware in an easy way.
final class SPISPI is a four wire serial protocol for communication between devices.
@frozen struct IntA signed integer value type.
func getMode() -> (CPOL: Bool, CPHA: Bool, bitOrder: BitOrder) Gets the SPI mode.
enum BitOrderThe bit order that the data is sent on SPI bus: MSB or LSB.
init(_ idName: Id, speed: Int = 5_000_000, csPin: DigitalOut? = nil, CPOL: Bool = false, CPHA: Bool = false, bitOrder: BitOrder = .MSB) Initializes a specified interface for SPI communication as a master device.
var CPHA: Bool { get }The phase to sample data, false for the first edge of the clock pulse, true for the second edge.
var CPOL: Bool { get }The state of SCK line when it’s idle.
var LSB: Bool { get }Whether the bit order is LSB.
var MSB: Bool { get }Whether the bit order is MSB.
var bitOrder: BitOrder { get }The bit order on data line.
var cs: Bool { get }A boolean value that tells whether the cs pin is set (true) or not (false).
let obj: UnsafeMutableRawPointervar speed: Int { get }The transmission speed of SPI communication.
