Split an integer to as many 7-bit parts as needed so it can be sent using the firmata protocol

Demo Code


using System.Collections.Generic;

public class Main{

        /// Split an integer to as many 7-bit parts as needed so it can be sent using the firmata protocol
        /// </summary>
        /// <param name="value">The integer value we want to convert</param>
        /// <param name="minimumBytes">This is used to ensure that </param>
        /// <returns>A series of 7-bit values representing the value</returns>
        public static IEnumerable<byte> GetBytesFromInt(int value,int minimumBytes = 2)
        {//from   w w w .  j ava 2s  . co  m
            while (true)
            {
                // There is no need to send another byte (everything will be 0 from now on)
                if ( minimumBytes-- <= 0 && value <= 0 )
                    yield break;

                // Cache the value we want to return
                byte returnValue = (byte) (value & 0x7f);
                // Prepare the value for the next iteration
                value = value >> 7;
                // yield return the current 7-bit value
                yield return returnValue;
            }
