    uart in c --- ich hänge

    Anzeige

    Powerstation Test
    bräuchte mal hilfe!
    bin neu in das thema eingestiegen: habe einen simplen code für kommunikation geschrieben, es kommuniziert aber nix.

    musste auf c umsteigen, da Bascom nur 4kB in der demoversion verarbeitet.
    kann mal jemand über meinen code drüberschauen, hab das makefile auch angeheftet:

    Code:
    #include <avr/io.h>
    #include <avr/interrupt.h>
    
    
    
    #define BAUD        19200UL
    #define UBRR_BAUD   ((F_CPU/(16UL*BAUD))-1)
    
    void uart_init(void)
    {
        // Baudrate einstellen (Normaler Modus)
        UBRRH = (unsigned char) (UBRR_BAUD>>8);
        UBRRL = (unsigned char) (UBRR_BAUD & 0x0ff);
    
        // Aktivieren des Empfängers, des Senders und des "Daten empfangen"-Interrupts
        UCSRB = (1<<RXCIE)|(1<<RXEN)|(1<<TXEN);
    
        // Einstellen des Datenformats: 8 Datenbits, 1 Stoppbit
        UCSRC = (1<<URSEL)|(1<<UCSZ1)|(1<<UCSZ0);
    }
    
    
    int main(void)
    {
        // USART initialisieren
        uart_init();
    
    	
    	// LED anmachen zum darstellen der bereitschaft
            DDRB   = 0b00000001;              //  geändert
            PORTB |= (1<<1);                    //   geändert
            PORTA |= (1<<1);    //falsch
    
    
    	
    	//interrupts aktivieren
        sei();
    	
    	
    	//hauptschleife (debug)
    	while(1);
    	{	
    	for (int i=0; i<100; i++)
    		{
    	    // ... warten bis der Sendepuffer leer ist ...
    		while ( !( UCSRA & (1<<UDRE)) );	
    			
    		UDR = i;
    		}
    	
    	}
    
        //// Nichts tun. Die Interrupts erledigten den Rest
        //while (1);
    }
    
    // Interrupt wird ausgelöst sobald neue Daten im USART-Empfangspuffer liegen
    SIGNAL(SIG_UART_RECV)
    {
        unsigned char buffer;
    
        // Daten aus dem Puffer lesen ...
        buffer = UDR;
    
        // ... warten bis der Sendepuffer leer ist ...
        while ( !( UCSRA & (1<<UDRE)) )
            ;
        // ... und gleich wieder zurück schicken
        UDR = buffer;
    }

    # make clean = Clean out built project files.

    # make coff = Convert ELF to AVR COFF.

    # make program = Download the hex file to the device, using avrdude.

    #
    # make debug = Start either simulavr or avarice as specified for debugging,

    #
    # make filename.s = Just compile filename.c into the assembler code only.

    Der Mega8 hat kein PortA.
    Wenn du eine Led an ein Port machen willst, dann zuerst DDRx setzen.
    Wenn du das AVR-Studio verwendest brauchst du kein Makefile.
    Sonst sehe ich auf die Schnelle keinen Fehler.
    Sonst Hardware sicher OK?

    DANKE

    das mit dem PORTA hab ich auch schon gesehen, war aber nicht so wichtig.

    Der Fehler war, dass ich in der Taktfrequenz 'ne 0 zu viel hatte,
    der Teil mit dem Empfangen und wieder zurückschicken funktioniert jetzt auch.

    Es bleibt lediglich das Problem, dass er mir aus der inneren Schleife keine Daten sendet.

    Hast du vielleicht nen Ansatz für mich??

    da hat sich ein semikolon hinter dein while geschmuggelt! weis nciht obn absichtlich doer nciht, jedenfalls schleift er sich im das while dusselig uind ignoriert die nachfolgenden geschweiften klammern ...

    ich glaube dein hyperterminal wird dich erschlagen wenn du es so zubombadierst! versuchs doch mal andersherum

    schreib deine daten in deiner ISR in einen puffer und in der hauptschleife zählst du nur die bytes im puffer mit und was das eltzte zeichen war, wenn da ein \r oder ein \n steht, liest du ein, was davor steht und gibst es aus (\n ist das standard terminalzeichen in C, \r glaube ich aber im terminal, deswegen solltest du auf beides prüfen) ... vergiss dann nur nicht den puffer zurückzusetzen ^^

    Zur Untersützung des Themas hier:
    http://www.tschallener.net/AVR/intr_usart.pdf

    in der pdf ist unten noch ein Link, dann kannste Dir ein eigenes Headerfile zusammenstellen mit den Funktionen/Prototypen die Du brauchst.

    Mir hat es sehr geholfen!
