概要

elm327の研究やってみた。
練習問題やってみた。

練習問題

c#で、ELM327のエミュレータを書け。

サンプルコード


using System;
using System.IO.Ports;
using System.Threading;
using System.Globalization;

public class ELM327 {
	public string talk(string a) {
		string res = "";
		string ans = "4" + a.Substring(1, 2) + " ";
		if (a.Substring(0, 3) == "ATZ")
			res += "ELM327 v1.4";
		else if (a.Substring(0, 2) == "AT")
			res += "OK";
		else if (a.Substring(0, 5) == "01 00")
			res += "41 00 FF FF FC FF";
		else if (a.Substring(0, 5) == "01 01")
			res += "41 01 84 07 61 00";
		else if (a.Substring(0, 5) == "01 20")
			res += "41 20 FF FF FC FF";
		else if (a.Substring(0, 5) == "01 40")
			res += "41 40 FF FF FC FF";
		else if (a.Substring(0, 5) == "01 60")
			res += "41 60 FF FF FC FF";
		else if (a.Substring(0, 5) == "01 80")
			res += "41 80 FF FF FC FF";
		else if (a.Substring(0, 5) == "01 A0")
			res += "41 A0 FF FF FC FF";
		else if (a.Substring(0, 5) == "01 C0")
			res += "41 C0 FF FF FC FF";
		else if (a.Substring(0, 2) == "01")
				res += ans + "00 00 00 00";
		else if (a.Substring(0, 2) == "03")
			res += "43 03 00 03 01 03\r\n43 13 01 04";
		else if (a.Substring(0, 5) == "09 02")
			res += "49 02 1Z3768470804";
		else
		{
			res += ans + " NO DATA\n";
		}
		return res;
	}
}
public class Program {
	public static void Main() {
		var elm = new ELM327();
		bool flg = true;
		while (flg)
		{
			string a;
			Console.Write(">");
			a = Console.ReadLine();
			var len = a.Length;
			if (a == "")
				flg = false; 
			Console.WriteLine(elm.talk(a));
		}
		Console.WriteLine("bai!");
	}
}




実行結果

>elm1
>ATZ
ELM327 v1.4
>01 00
41 00 FF FF FC FF
>01 22
41  00 00 00 00
