Programm verzögert

Hallo,

Da ich neu bin weiß ich leider nicht, ob das hier im richtigen Bereich ist. Ich bitte um Verständnis.

Ich habe ein Programm geschrieben, welches Daten aus dem Spiel Project Cars ausliest, diese verarbeitet und dann an einen Arduino weiterleitet.
Jetzt habe ich aber das Problem, dass nach dem das Programm eine Weile lief, die Ausgabe verzögert ist. Also kommt die Nachicht erst nach 1-2 Sekunden an.

Könnt ihr mir Tipps geben, wie ich das ganze verhindern kann?

Sorry das ich jetzt den ganzen Code hochgeladen habe, aber ich weiß nicht wo die Bremse ist.

PS: Ich habe die main.cpp geschrieben, die Restlichen habe ich nur inkludiert.

Main\1:

// Used for memory-mapped functionality
#include <windows.h>
#include <stdio.h>
#include <conio.h>
#include "tserial.h"
#include "bot_control.h"
#include "sharedmemory.h"

// Name of the pCars memory mapped file

#define MAP_OBJECT_NAME "$pcars$"

//Konstanten

const bool debug = true;
const unsigned char maxFPS = 100;
const unsigned char fuelWarn = 10;

char data; //To store the character to send
char lastFlag;

serial comm; //serial is a class type defined in these files, used for referring to the communication device

int main() {

	// Open the memory-mapped file
	HANDLE fileHandle = OpenFileMapping( PAGE_READONLY, FALSE, MAP_OBJECT_NAME );
	if (fileHandle == NULL)
	{
		printf( "Could not open file mapping object (%d).\n", GetLastError() );
		Sleep(2000);
		return 1;
	}

	// Get the data structure
	const SharedMemory* sharedData = (SharedMemory*)MapViewOfFile( fileHandle, PAGE_READONLY, 0, 0, sizeof(SharedMemory) );
	if (sharedData == NULL)
	{
		printf( "Could not map view of file (%d).\n", GetLastError() );

		CloseHandle( fileHandle );
		Sleep(2000);

	}

	// Ensure we're sync'd to the correct data version

			system("cls");
		}

		if(lastFlag != sharedData->mHighestFlagColour){
			data = sharedData->mHighestFlagColour;
			lastFlag = data;
		}

		comm.send_data(data); //The data is sent through the arduino

		if ( _kbhit() && _getch() == 27 ) // check for escape
		{
			break;
		}

		Sleep(1000 / maxFPS);
	}

	// Cleanup
	UnmapViewOfFile( sharedData );
	CloseHandle( fileHandle );

	comm.stopDevice(); //The device is closed down
	getch();

	return 0;
}

Du glaubst doch nicht im Ernst, dass sich das jemand anguckt, oder? Zumal die Fehlerbeschreibung zu wünschen lässt: Welche Ausgabe ist verzögert? Wie merkst du das? Hat das vielleicht etwas mit deinen ganzen sleeps zu tun?

Aber allgemein:
Wie man Probleme nachstellbar und nachvollziehbar macht
Lesen, verstehen, dann bessere Frage stellen.

Sorry, ich weiß nicht wirklich wodurch das Problem entsteht, deshalb habe ich den kompletten Quelltext hinzugefügt.

In dem Programm werden Daten aus einem Spiel ausgelesen. Dabei erscheint aber erst ein paar Sekunden nach dem Ingame der Wert erscheint, die Ausgabe über die Konsole:

printf( "Flag: (%d)\n", sharedData->mHighestFlagColour );

Das liegt wahrscheinlich nicht an den Sleeps, da diese nicht so lang sind, sondern diese sind dafür da damit das Skript nicht zu überlasstend wird. An der Überlasstung liegt es nicht da das Skript nur 1 Mb RAM verbraucht.

Dann versuch es einzukreisen! Darum habe ich dir doch den Link gegeben. Niemand durchforstet auf gut Glück tausende Zeilen Code nach einem vage spezifizierten Fehler. Ohne das zugehörige Gegenstück können wir das Programm ja nicht einmal ausprobieren!

Und was ist mit der Gegenseite? Wie kommen die Daten zu deinem Programm?

So, habe soeben tausende Zeilen Code auf gut Glück nach einem vage spezifizierten Fehler durchforstet.

Bei der Zeit klingt das eher so, als wäre das ein lockerer Waldlauf gewesen

Das Problem tritt auf, weil irgendwie die Main-Loop nicht schnell genug durchlaufen werden kann.

EDIT: Jetzt habe ich den Fehler! Das Problem war diese Zeile:

comm.send_data(data);

Diese wurde zu oft (sinnlos) durchlaufen und somit war der Arduino überlasstet.
