串口编程补充

首先声明此文只适合我这等串口编程新手,也欢迎大神吐槽

参数转换问题:

 /// <summary>        /// 数据转换        /// </summary>        /// <param name="values">要转换的byte数组</param>        /// <param name="factor">计算因子</param>        /// <param name="reh">高位字符</param>        /// <returns></returns>        private double ByteConvertDouble(byte[] values,int factor = 0, bool reh = false)        {            string hexStr = string.Empty;            for (int i = 0; i < values.Length; i++)            {                hexStr += GetHexStr(values[i]);            }            if (reh)                hexStr = hexStr.Substring(1);            double temp = Convert.ToInt32(hexStr, 16) * Math.Pow(0.1, factor);            if (reh)                temp *= (-1);            return temp;        }        /// <summary>        /// byte 转十六进制字符        /// </summary>        /// <param name="b"></param>        /// <returns></returns>        private string GetHexStr(byte b)        {            return (b / 16).ToString("X") + (b % 16).ToString("X");        }

 取数据时要看其所占的位数
