AVR Studio, Atmega8, C ++, CTC timer

Hello, I have a problem with my code. Namely, if my program is used in the ISR will my display of comic characters. Since my debugger does not work I can not move to full and I'm just not there anymore. Here is my code:

#define F_CPU 3686400 #include <avr/io.h> #include <avr/delay.h> //Delays //Muss über der lcdlib.h stehen sonst fehler da man delay in der lcdlib.h braucht #include <avr/interrupt.h> #include <arndt/lcdlib.h> //Notwendig für das LCD-Display // Befehle für das Display ISR (TIMER1_COMPA_vect); int main(void) { lcdInit(); //Iinitialisierung DDRC = 0x00; //Eingang PORTC = 0xFF; //Pull-up int Pumpe; Pumpe = 0; //Pumpe Nullsetzten, wird im Hauptprogramm gesetzt und Definiert ** while(1) { lcdGoto(2,1);lcdWrite("1"); if (!(PINC&0b000010)) //Wenn die If-bedingung drin ist Zeigt das LcdDisplay lustige Zeichen an nach dem es wahr wurde //Zum kontrolierten Start des Programms { lcdGoto(1,14);lcdWrite("Q"); // If (Pumpe = 1) //Soll erst gemacht werden, wenn Pumpe = 1, 5 sec lang an ist //Wir später gemacht // { //Timer0 konfigurieren TCCR1A = (1<<WGM10); //CTC Modus aktiv TCCR1B |=(1<<CS11)|(0<<CS10); //Prescaler8 // (1<<CS10)|(1<<CS11) Prescaler 64 // TCNT1 = 0; //Timer Intitialisieren //Keine sichtbaren Veränderungen // TCCR1B |= 0x08; //Modus: Zählen bis Vergleichswert //Überflüssig OCR1A = 460800-1; //Vergleichswert speichern 5sec //Berechnungsformel((Frequenz/Prescaler)/Zeit in ms) TIMSK|= 0x10; // Interrupt bei vergleichswert sei(); //Global Interrupts erlauben // } lcdGoto(1,15);lcdWrite("W"); //Hier kommt das Programm nie hin, WARUM }** }

}

ISR (TIMER1_COMPA_vect) //Interrupt bei Vergleichswert CompA //Muss sich den Wert aus Pumpe mitnehmen { cli(); //Interrupts sperren DDRC = 0x00; //Eingang PORTC = 0xFF; //Pull-up int Pumpe; //Test Variable für das Hauptprogramm // lcdClear(); lcdGoto(1,1);lcdWrite("Pumpenfehler"); if(!(PINC = 0x01)) //Test { Pumpe = 1; //Pumpe an //Zustand = 1; } sei(); //Interrupts erlauben

} // (Return pump) Must the value in return pump in pump

Image with the sign still follows and schonmal Thanks in advance.

The best answer

The two ** before while (1) and after} (from while (1) do not do not belong. White but how I can change it in the question :)
