STM32串口调试助手接收HEX格式FF 2C

STM32发送数据,可是串口调试助手一直接收的是FF,换波特率接受干脆就停止了。请问是怎么回事啊,有没有可能是串口线坏掉了

2个回答

只有串口调试助手设置的串口参数,和stm32程序设置的参数一样才能正常收发数据。当然也不排除串口线的RX坏掉了,换根串口线试试

惨不忍睹帅 嗯嗯,如果串口接收到了数据是不是表明软件的串口配置没什么问题?

stm32 如何在 KEIL 中 建立内部 EEPROM HEX 文件
我以前用过51,会建立两个project target,一个是CORE 用来跑main(),一个EEPROM 里面只有一个eeprom.c 里面没有函数只有一个u8数组,烧写的时候会把eeprom.hex中的数组下载到单片机的类eeprom中,然后主程序初始化的时候将eeprom.c 数组中的数据全部读出来,并按照相应地址映射到变量中,今天在STM32上研究很久建立eeprom工程,所以我也同样只在eeprom.c中定义一个数组,没有定义其他函数,也没有加启动文件,于是出现下面的错误 ..\OBJ\eeprom.sct(7): error: L6236E: No section matches selector - no section to be FIRST/LAST.,有没有哪位大神知道的帮帮忙指导下谢谢。
请问,用STLink 烧录程序进stm32,连接正常,后面每次都烧录的是出错之前的程序,怎么解决?
请问,用STLink 烧录程序进stm32,连接正常,烧录进去了,但是没有现象。 之前用mcu的串口下载程序的时候,如果只是选择默认的而不点击hex文件也会出现上面的问题。就烧录的是出错之前的文件,后面编译的文件没烧录进去

Hex Tile Equations 等式问题
Problem Description An amusing puzzle consists of a collection of hexagonal tiles packed together with each tile showing a digit or '=' or an arithmetic operation '+', '-', '*', or '/'. Consider continuous paths going through each tile exactly once, with each successive tile being an immediate neighbor of the previous tile. The object is to choose such a path so the sequence of characters on the tiles makes an acceptable equation, according to the restrictions listed below. A sequence is illustrated in each figure above. In Figure 1, if you follow the gray path from the top, the character sequence is"6/3=9-7". Similarly, in Figure 2, start from the bottom left 3 to get "3*21+10=73". There are a lot of potential paths through a moderate sized hex tile pattern. A puzzle player may get frustrated and want to see the answer. Your task is to automate the solution. The arrangement of hex tiles and choices of characters in each puzzle satisfy these rules: The hex pattern has an odd number of rows greater than 2. The odd numbered rows will all contain the same number of tiles. Even numbered rows will have one more hex tile than the odd numbered rows and these longer even numbered rows will stick out both to the left and the right of the odd numbered rows. 1.There is exactly one 2. '=' in the hex pattern. 3. There are no more than two '*' characters in the hex pattern. 4. There will be fewer than 14 total tiles in the hex pattern. 5.With the restrictions on allowed character sequences described below, there will be a unique acceptable solution in the hex pattern. To have an acceptable solution from the characters in some path, the expressions on each side of the equal sign must be in acceptable form and evaluate to the same numeric value. The following rules define acceptable form of the expressions on each side of the equal sign and the method of expression evaluation: 6.The operators '+', '-', '*', and '/' are only considered as binary operators, so no character sequences where '+' or '-' would be a unary operator are acceptable. For example "-2*3=-6" and "1 =5+-4" are not acceptable. 7.The usual precedence of operations is not used. Instead all operations have equal precedence and operations are carried out from left to right. For example "44-4/2=2+3*4" is acceptable and "14=2+3*4" is not acceptable. 8.If a division operation is included, the equation can only be acceptable if the division operation works out to an exact integer result. For example "10/5=12/6" and "7+3/5=3*4/6" are acceptable. "5/2*4=10" is not acceptable because the sides would only be equal with exact mathematical calculation including an intermediate fractional result. "5/2*4=8" is not acceptable because the sides of the equation would only be equal if division were done with truncation. 9.At most two digits together are acceptable. For example, " 9. 123+1 = 124" is not acceptable. 10.A character sequences with a '0' directly followed by another digit is not acceptable. For example,"3*05=15" is not acceptable. With the assumptions above, an acceptable expression will never involve an intermediate or final arithmetic result with magnitude over three million. Input The input will consist of one to fifteen data sets, followed by a line containing only 0. The first line of a dataset contains blank separated integers r c, where r is the number of rows in the hex pattern and c is the number of entries in the odd numbered rows. The next r lines contain the characters on the hex tiles, one row per line. All hex tile characters for a row are blank separated. The lines for odd numbered rows also start with a blank, to better simulate the way the hexagons fit together. Properties 1-5 apply. Output There is one line of output for each data set. It is the unique acceptable equation according to rules 6-10 above. The line includes no spaces. Sample Input 5 1 6 / 3 = 9 - 7 3 3 1 + 1 * 2 0 = 3 3 7 5 2 9 - * 2 = 3 4 + 8 3 4 / 0 Sample Output 6/3=9-7 3*21+10=73 8/4+3*9-2=43
Hex Factorial 的计算
Problem Description The expression N!, reads as the factorial of N, denoting the product of the first N positive integers. If the factorial of N is written in hexadecimal without leading zeros, can you tell us how many zeros are there in it? Take 15! as an example, you should answer "3" because (15)10! = (13077775800)16, and there are 3 zeros in it. Input The input contains several cases. Each case has one line containing a non-negative decimal integer N (N ≤ 100). You need to count the zeros in N! in hexadecimal. A negative number terminates the input.

求助大佬!感谢! 1、只要串口接收到的数据流中存在0x1A,就会抛出“索引超出数组界限”。 2、关键代码如下: ``` private void Form1_Load(object sender, EventArgs e) { sp1.Parity = Parity.None; sp1.BaudRate = int.Parse("9600"); sp1.ReceivedBytesThreshold = 5; //设置触发字节数 //--------------------------------------------------------------------- Control.CheckForIllegalCrossThreadCalls = false; // sp1.DataReceived += new SerialDataReceivedEventHandler(sp1_DataReceived); //串口接收事件 sp1.DtrEnable = true; sp1.RtsEnable = true; sp1.ReadTimeout = 1000; sp1.Close(); } ``` ``` private void button_open_Click(object sender, EventArgs e) { try { sp1.Open(); } catch { sp1.Close(); MessageBox.Show("没有此串口!"); } } ``` ``` void sp1_DataReceived(object sender, SerialDataReceivedEventArgs e) { if (sp1.IsOpen) { byte[] byteRead = new byte[sp1.BytesToRead]; //获取串口接收缓冲区中字节数 try { Byte[] receivedData = new Byte[sp1.BytesToRead]; sp1.Read(receivedData, 0, receivedData.Length); this.Invoke(new EventHandler(delegate { textBox1.Text = Convert.ToString(receivedData.Length); })); sp1.DiscardInBuffer(); //clear //------------------------------------------------- if (receivedData[0] == 0xAA && receivedData[1] == 0x55) { string Recostr = string.Empty; if (DataType == 0) Recostr = "Hex: " + arr2string(receivedData, 0, receivedData.Length); else Recostr = "Dec: " + arr2string(receivedData, 0, receivedData.Length); RecodLine = DateTime.Now.ToString("G") + " " + Recostr; this.Invoke(new EventHandler(delegate { listBoxAutoRefesh(RecodLine); })); receok = true; } } catch (System.Exception ex) { sp1.DiscardInBuffer(); MessageBox.Show(ex.Message, "出错提示"); } } } ``` 3、现象截图如下: ![图片说明](https://img-ask.csdn.net/upload/201908/26/1566806558_35429.png) 4、接收数据流验证过百来个字节,经实验,只要数据流中任何位置存在0x1A,都会抛出“索引超出数组界限”异常。
C# HttpWebResponse如何获取response body的HEX格式的数据?
``` public static string Post(string url, string content) { string result = ""; #region 添加Post 参数 byte[] data = Encoding.UTF8.GetBytes(content); try { HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url); req.Method = "POST"; req.KeepAlive = false; req.ContentType = "application/x-www-form-urlencoded"; req.ContentLength = data.Length; Stream reqStream = req.GetRequestStream(); reqStream.Write(data, 0, data.Length); reqStream.Close(); #endregion HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); Stream stream = resp.GetResponseStream(); //获取响应内容 using (StreamReader reader = new StreamReader(stream, Encoding.UTF8)) { result = reader.ReadToEnd(); req.Abort(); } return result; } return ""; } ``` 请问这个代码如何修改得到HEX数据?
QR 的问题
Problem Description QR Codes (the smallest, which is 21 pixels by 21 pixels, is shown below) are square arrays of black or white pixels (modules) which include Position Detection Patterns (the square bull's-eye patterns), Timing Patterns (the alternating black and white lines), Alignment Patterns in larger QR Codes , Format Information (the stippled pixels), Version information in larger QR Codes and Data and Error Correction Codewords (gray 8 pixel blocks). The 21-by-21 QR Code has 26 data and error correction codewords. At the lowest error correction level for this code, 19 are data codewords and 7 are error correction codewords. Data may be encoded as numeric at 3 numbers per 10 bits, as alphanumeric at 2 characters per 11 bits, as 8 bit bytes or as Kanji at 13 bits per character. Data is encoded in groups of(mode,character count,character data bits).The mode can change within the data stream. The mode is specified by a 4 bit code and the character count by a varying number of bits depending on the mode and QR Code size. For the 21-by-21 code, the character count bits are: The entire data stream ends in the termination code which may be truncated if there is not enough room. Any partially filled codeword after the termination code is filled with 0 bits. Any remaining codewords are set to 11101100 followed by 00010001 alternating. Numeric strings are encoded 3 digits at a time. If there are remaining digits, 2 digits are encoded in 7 bits or 1 digit in 4 bits. For example: 12345678 -> 123 456 78 -> 0001111011 0111001000 1001110 Prefix with mode (0001) and count (8 -> 0000001000) is (4 + 10 + 10 + 10 +7) bits: 0001 0000001000 0001111011 0111001000 1001110 Alphanumeric strings encode the haracters (<SP> represents the space character): 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ<SP>$%*+-./: as numbers from 0 to 44, then two characters are encoded in 11 bits: <first char code5> * 45 + <second char code> if the number of characters is odd, the last character is encoded in 6 bits. For example: AC-42 -> (10,12,41,4,2) -> 10*45+12=462, 41*45+4=1849, 2->00111001110 11100111001 000010 Prefix with mode and count is (4 + 9 + 11 + 11+ 6) bits: 0010 000000101 00111001110 11100111001 000010 The 8 bit binary and Kanji modes will be straightforward for the purposes of this problem. Kanji codes will just be opaque 13 bit codes; you need not decode the characters they represent, just the hexadecimal values. For example: 8 bit 0x45 0x92 0xa3 -> 01000101 10010010 10100011 Prefix with mode and count is (4 + 8 + 8 + 8 + 8) bits: 0100 00000011 01000101 10010010 10100011 Kanji 0x1ABC 07x0345 -> 1101010111100 0001101000101 Prefix with mode and count is (4 + 8 + 13 + 13) bits: 1000 00000010 1101010111100 0001101000101 To illustrate forming the 19 codeword content of a QR Code, combine the first 3 sequences above (for numeric, alphanumeric and bytes). Concatenate the bits, split into 8bit code words add the termination codeword, any fill bits and fill bytes (41 + 41 + 36 data bits + 4 bit termination code = 122 -> 6 fill bits are needed to get 16 bytes, and to fill out the 19 bytes, 3 fill bytes are needed): 0001 0000001000 0001111011 0111001000 1001110 0010 000000101 00111001110 11100111001 000010 0100 00000011 01000101 10010010 10100011 0000 000000 11101100 00010001 11101100 split into 8 bit codewords: 00010000 00100000 01111011 01110010 00100111 00010000 00010100 11100111 01110011 10010000 10010000 00001101 00010110 01001010 10001100 00000000 11101100 00010001 11101100 -> HEX 10207B72271014E77390900D164A8C0EC11EC Write a program to read 19 codewords and print the orresponding data. Input The first line of input contains a single integer P, (1 <= P <= 1000), which is the number of data sets that follow. Each data set is a single line of input consisting of the data set number, N, followed by a single space and 38 hexadecimal digits giving the 19 bytes of QR Code data. The valid hexadecimal digits are 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E and F. Output For each data set there is one line of output. It contains the data set number (N) followed by a single space, the number of QR decoded characters in the result, a single space and the character string corresponding to the QR Code data. In the output string, printable ASCII characters (in the range 0x20 to 0x7e) are printed as the ASCII character EXCEPT that backslash (\) is printed as \\ and pound sign (#) is printed as \#. Non-printable 8 bit data is output as \xx, where x is a hexadecimal digit (e.g. \AE). Non-printable 8 bit data is any value that is less than the ASCII value of a space (0x20) or greater than 0x76. 13 bit Kanji values are printed as #bxxx, where b is 0 or 1 and x is a hexadecimal digit (e.g. #13AC).

只能读取传感器16进制的输出而无法读取ASCII; 16进制转ASCII码
使用串口调试助手读取传感器的数据时,发现遇到如下情况: 1 在接收设置里选择 Hex,则读出的数据为16进制数 2 若在接收设置里ASCII, 则读出的数据为乱码 3 使用16进制转ASCII工具,将从传感器读取的16进制数据转出的结果仍旧为乱码 谁能解释一下原因? 谢谢!
