A smart car uses an on-board camera to collect runway data and then stores the data in the memory of the Central Control Board of the car. After the vehicle runs for a week, serial communication is sent to the computer and saved as a binary file.

The software then reads the binary file, reads 40*80 = 3200 data at a time, then draws 3200 gray pixels with GDI, and uses the timer, reading data from the file and re-drawing the file at intervals, this animation is similar to the player function.

This is a software written in vc6.0 when I was a junior. Now I want to, but it is not very practical. I can only collect on-site data and perform some host computer simulation. However, it's just a little effort of my junior year. Now clean up the hard disk, and make a video of the effect demonstration of the software, as a souvenir, and then delete it.

 

The main technical problems are reading files, GDI plotting, and timer.

1. Read files

 Void Cpicmoviedlg: onopenfile (){ // Todo: add your control notification handler code here  // Open the file  // Create a file name cache (filebuffer) and a file read cache (rbuffer)  // If the cache is not set here, an error will occur in the subsequent settings. If the request is dynamic, use memset or for loop to clear the Array  Char Filebuffer [5010] = {0}, rbuffer [row * column] = {0 }; // Define a cfile class to process files // Cfile in; // put it in the member variables in this dialog box. Because I want to continue to operate this file. There must be a long generation cycle .??? Balance Measure  // Define a cfiledialog class to display the standard open file dialog box Cfiledialog indlg (false, null, _ T (" Custom file type (*. Sav) | *. Sav | all files (*. *) | *. * | "), Null); indlg. m_ofn.lpstrtitle = _ T (" Open a custom file "); // Set a file name cache, because the built-in file name cache length of cfiledialog is only, but in many cases, the file path is much larger than this number. To be safe, you must set a file name cache. Indlg. m_ofn.lpstrfile = filebuffer; // Set the cache Length Indlg. m_ofn.nmaxfile = 5000; // Display the dialog box and process the events with the OK button  If (Indlg. domodal () = idok ){ // Open the file in read-only mode If (In. Open (indlg. getpathname (), cfile: moderead) {operatefile (); bstopflag = 1; // The file is not automatically played after it is opened.  // Close the file  // In. Close (); // place the statement inProgramEnd Time.  // MessageBox ("file opened successfully", "done", mb_iconexclamation | mb_ OK ); } Else {MessageBox (" Opening the file failed. You may not close the current file. "," Failed ", Mb_iconstop | mb_ OK); bopenflag = 0 ;}}}

 

 

 

2. pixels drawn by GDI

 

VoidCpicmoviedlg: draworigin (byte datatemp [] [column], CDC * PDC ){For(IntI = 0; I <row; I ++)For(IntJ = 0; j <column; j ++ ){IntRecwidth = 8;IntRecheight = 14; colorref clrrec = RGB (datatemp [I] [J], datatemp [I] [J], datatemp [I] [J]); PDC-> rectangle (recwidth * j/2, recheight * I/2, recwidth * (J + 1)/2, recheight * (I + 1)/2 );// The following Fill function overwrites all the original paint effects.PDC-> fillsolidrect (recwidth * j/2, recheight * I/2, recwidth/2, recheight/2, clrrec );}}
 

 

 

 

 

3. Timer

 

When the dialog box is initialized, set the timer and then execute the drawing function in the timer event. For more information about the usage, visit the internet.
