What is this repository for?

Tiny and cross-device compatible CRC16 XModem calculator library

Compatible with UKHAS.org.uk message signing, use offset 2 on full message to skip leading "$".

Supports any microcontroller.

Usage

This library is used with only static methods, you don't need to (and can't) initialize any class object.

You have these methods:

• uCRC16XModemLibObject.reset() : Resets internal state
• uCRC16XModemLibObject.feedBit(bool) : Feeds a bit
• uCRC16XModemLibObject.feedByte(char) : Feeds a byte
• uCRC16XModemLibObject.getResult() : Gets CRC16 in a uint16_t

Library provides also two shorthand methods:

• uint16_t CRC = uCRC16XModemLibObject.calculate(MessageCharArray) : Calculates CRC for a message
• uint16_t CRC = uCRC16XModemLibObject.calculate(MessageCharArray, 2) : Calculates CRC for a message starting from offset 2 (recommended use for UKHAS.org.uk)

How do I get set up?

You can get it from Arduino libraries directly, searching by uCRC16XModemLib.

For manual installation:

• Get the ZIP from releases link: https://github.com/Naguissa/uCRC16XModemLib/releases
• Rename to uCRC16XModemLib.zip
• Install library on Arduino

Examples

Included on example folder, available on Arduino IDE.
