一、摘要

1.描述

本文主要描述的是如何通过使用C#解析常用MCU的刷写格式文件，如Bin，S19，Hex，Mot，Serc。
本软编写的语言是基于C#语言，并未使用其他关联的DLL文件，所以不同的电脑之间兼容性很好，不会出现调用异常的问题。
郑重申明，关于实现方法，我也是从网上很多地方学习而来，大家若觉得版权问题可以联系我随时删除。

2.关键字

文件解析，C#，Bin，S19，Hex，Mot，Serc。

二、为何选择C#解析

C#解析文件有很多好用的字符串处理函数，不过其实方式方法都一样，只要知道了解析方法，使用任何语言都是一样轻松的。

三、BIN文件解析

     /*-----define---------------------------------*/private const int BLOCK_BUFF_LEN = 83886080;private const byte MOT_LINE_LEN = 16;private const byte HEX_LINE_LEN = 16;/*-----enum and struct------------------------*/private class DataInfo_Type{internal int len;internal uint startAddr;internal uint endAddr;internal byte[] buff;}/*-----variable statement---------------------*/private readonly List<DataInfo_Type> g_DataInfos = new List<DataInfo_Type>();/************************************************ Name    :PushDataInfo* Author  :WangHu* Function:**** Version :V1.0.0* Data    :2022.5.20***********************************************/private void PushDataInfo(uint? startAddr, uint? endAddr, uint? minStartAddr, uint? maxEndAddr, byte[] p_buff, int len){int m = 0; int n = 0;if (minStartAddr == null) { minStartAddr = 0; }if (maxEndAddr == null) { maxEndAddr = 0xFFFFFFFF; }if ((startAddr > maxEndAddr) || (endAddr < minStartAddr)) { return; }if (startAddr < minStartAddr) { m = (int)(minStartAddr - startAddr); }if (endAddr > maxEndAddr) { n = (int)(endAddr - maxEndAddr); }len = len - m - n;DataInfo_Type dataInfo = new DataInfo_Type{len = len,startAddr = (uint)(startAddr + m),endAddr = (uint)(endAddr - n),buff = new byte[len]};CommonLib.Copy(dataInfo.buff, p_buff, m, len);g_DataInfos.Add(dataInfo);}/************************************************ Name    :AnalysisBinFile* Author  :WangHu* Function:**** Version :V1.0.0* Data    :2022.5.20***********************************************/private bool AnalysisBinFile(string path, uint? minStartAddr, uint? maxEndAddr){try{FileStream file = new FileStream(path, FileMode.Open);int lenth = (int)file.Length;if (lenth == 0) { return false; }byte[] data = new byte[BLOCK_BUFF_LEN];uint? startAddr = minStartAddr;if (startAddr == null) { startAddr = 0; }uint? endAddr = (uint?)(startAddr + lenth - 1);_ = file.Read(data, 0, lenth);PushDataInfo(startAddr, endAddr, minStartAddr, maxEndAddr, data, lenth);file.Close();return true;}catch { return false; }}

四、BIN文件生成

     /************************************************ Name    :StorageBinFile* Author  :WangHu* Function:**** Version :V1.0.0* Data    :2022.5.20***********************************************/private bool StorageBinFile(string path, uint startAddr, byte[] p_buff, int len){try{Stream file = new FileStream(path, FileMode.Create);BinaryWriter binWriter = new BinaryWriter(file, Encoding.Unicode);binWriter.Write(p_buff, (int)startAddr, len);binWriter.Close();file.Close();return true;}catch { return false; }}

五、S19，M0T，SREC文件解析

     /************************************************ Name    :MotCheckSum* Author  :WangHu* Function:**** Version :V1.0.0* Data    :2022.5.20***********************************************/private byte MotCheckSum(byte[] buff, int len){byte ret = 0x00;for (int i = 0; i < len; i++) { ret += buff[i]; }return (byte)(0xFF - ret);}/************************************************ Name    :AnalysisMotFile* Author  :WangHu* Function:**** Version :V1.0.0* Data    :2022.5.20***********************************************/private bool AnalysisMotFile(string path, uint? minStartAddr, uint? maxEndAddr, List<string> ignoreLines){int lenth = 0;uint? startAddr = null;uint? endAddr = null;byte[] data = new byte[BLOCK_BUFF_LEN];StreamReader reader = new StreamReader(path);while (true){string line = reader.ReadLine();if (line == null) { break; }if (line == string.Empty) { continue; }if (ignoreLines != null) { foreach (string str in ignoreLines) { if (str == line.Replace(" ", "")) { continue; } } }string type = line.Substring(0, 2);int len = (line.Length / 2) - 1;if (len != (Convert.ToInt32(line.Substring(2, 2), 16) + 1)){reader.Close();reader.Dispose();return false;}byte[] buff = new byte[256];for (int i = 0; i < len; i++) { buff[i] = Convert.ToByte(line.Substring((i + 1) * 2, 2), 16); }if (buff[len - 1] != MotCheckSum(buff, len - 1)){reader.Close();reader.Dispose();return false;}uint address;switch (type){case "S1":address = 0;address |= ((uint)buff[1]) << 8;address |= ((uint)buff[2]) << 0;if (startAddr == null) { startAddr = address; }if ((endAddr != null) && (address != (endAddr + 1))){PushDataInfo(startAddr, endAddr, minStartAddr, maxEndAddr, data, lenth);lenth = 0;startAddr = address;}endAddr = address + (uint)(len - 4) - 1;CommonLib.Copy(data, lenth, buff, 3, len - 4);lenth += len - 4;break;case "S2":address = 0;address |= ((uint)buff[1]) << 16;address |= ((uint)buff[2]) << 8;address |= ((uint)buff[3]) << 0;if (startAddr == null) { startAddr = address; }if ((endAddr != null) && (address != (endAddr + 1))){PushDataInfo(startAddr, endAddr, minStartAddr, maxEndAddr, data, lenth);lenth = 0;startAddr = address;}endAddr = address + (uint)(len - 5) - 1;CommonLib.Copy(data, lenth, buff, 4, len - 5);lenth += len - 5;break;case "S3":address = 0;address |= ((uint)buff[1]) << 24;address |= ((uint)buff[2]) << 16;address |= ((uint)buff[3]) << 8;address |= ((uint)buff[4]) << 0;if (startAddr == null) { startAddr = address; }if ((endAddr != null) && (address != (endAddr + 1))){PushDataInfo(startAddr, endAddr, minStartAddr, maxEndAddr, data, lenth);lenth = 0;startAddr = address;}endAddr = address + (uint)(len - 6) - 1;CommonLib.Copy(data, lenth, buff, 5, len - 6);lenth += len - 6;break;case "S7":case "S8":case "S9":break;default:break;}}if (lenth != 0) { PushDataInfo(startAddr, endAddr, minStartAddr, maxEndAddr, data, lenth); }reader.Close();reader.Dispose();return true;}

六、S19，M0T，SREC文件生成

     /************************************************ Name    :StorageMotFile* Author  :WangHu* Function:**** Version :V1.0.0* Data    :2022.5.20***********************************************/private bool StorageMotFile(string path, uint? startAddr, byte[] p_buff, int len){try{int lenth;int block = len / MOT_LINE_LEN;byte[] buff = new byte[256];if (startAddr == null) { startAddr = 0x00; }StreamWriter writeFile = new StreamWriter(path);string str = "S011000000486578766965772056312E3038D1";writeFile.WriteLine(str);if ((len % MOT_LINE_LEN) != 0) { block += 1; }byte addrLen = startAddr > 0xFFFFFF ? (byte)4 : (byte)3;for (int i = 0; i < block; i++){for (int j = 0; j < addrLen; j++) { buff[j + 1] = (byte)((startAddr + (i * MOT_LINE_LEN)) >> ((addrLen - j - 1) * 8)); }lenth = ((i + 1) * MOT_LINE_LEN) > len ? len - (i * MOT_LINE_LEN) : MOT_LINE_LEN;buff[0] = (byte)(lenth + addrLen + 1);CommonLib.Copy(buff, addrLen + 1, p_buff, MOT_LINE_LEN * i, lenth);buff[lenth + addrLen + 1] = MotCheckSum(buff, lenth + addrLen + 1);str = "S" + Convert.ToString(addrLen - 1, 16);str += CommonLib.ToStr(buff, lenth + addrLen + 2).Replace(" ", "");writeFile.WriteLine(str);}buff[0] = (byte)(addrLen + 1);CommonLib.Fill(buff, 1, 0xFF, 4);buff[addrLen + 1] = MotCheckSum(buff, addrLen + 1);str = "S" + Convert.ToString(11 - addrLen, 16);str += CommonLib.ToStr(buff, addrLen + 2).Replace(" ", "");writeFile.WriteLine(str);writeFile.Flush();writeFile.Close();return true;}catch { return false; }}
