Helper to easily generate CRC checksum in Swift. Validated by http://crccalc.com
Once you have your Swift package set up, adding CrcSwift as a dependency is as easy as adding it to the dependencies value of your Package.swift.
dependencies: [
.package(url: "https://github.com/ivanesik/CrcSwift.git", from: "0.0.3")
]To integrate CrcSwift into your Xcode project using CocoaPods, specify it in your Podfile:
pod 'CrcSwift', '~> 0.0.3'// A401000AFF061101011300D3
var dataArray: [UInt8] = [0xA4, 0x01, 0x00, 0x0A, 0xFF, 0x06, 0x11, 0x01, 0x01, 0x13, 0x00, 0xD3]
var data = Data(dataArray)
// With Mode variables presets and `[UInt8]` input
CrcSwift.computeCrc8(data, mode: .cdma2000) // 0xbe
CrcSwift.computeCrc16(data, mode: .modbus) // 0x71CA
CrcSwift.computeCrc32(data, mode: .mpeg2) // 0x72E70589
// With Mode variables presets and `Data` input
CrcSwift.computeCrc8(dataArray, mode: .cdma2000) // 0xbe
CrcSwift.computeCrc16(dataArray, mode: .modbus) // 0x71CA
CrcSwift.computeCrc32(dataArray, mode: .mpeg2) // 0x72E70589
// Or you can manually set your CRC variables
let manualCrc16 = computeCrc16(
data,
initialCrc: 0x0000,
polynomial: 0x8005,
