    #----------------------------------------------------------------------------
    # WinAVR Makefile Template written by Eric B. Weddington, Jörg Wunsch, et al.
    #
    # Released to the Public Domain
    #
    # Additional material for this makefile was written by:
    # Peter Fleury
    # Tim Henigan
    # Colin O'Flynn

    # Markus Pfaff

    # Frederik Rouleau
    # Carlos Lamas
    #
    #----------------------------------------------------------------------------
    # On command line:
    #
    # make all = Make software.
    #
    # make clean = Clean out built project files.
    #
    # make coff = Convert ELF to AVR COFF.
    #
    # make extcoff = Convert ELF to AVR Extended COFF.
    #
    # make program = Download the hex file to the device, using avrdude.
    #                Please customize the avrdude settings below first!
    #
    # make debug = Start either simulavr or avarice as specified for debugging, 
    #              with avr-gdb or avr-insight as the front end for debugging.
    #
    # make filename.s = Just compile filename.c into the assembler code only.
    #
    # make filename.i = Create a preprocessed source file for use in submitting
    #                   bug reports to the GCC project.

    # To rebuild project do "make clean" then "make all".

    #     calculate timings. Do NOT tack on a 'UL' at the end, this will be done
    #     automatically to create a 32-bit value in your source code.

    Hallo Bääääär,
    im Moment kann ich nur feststellen, dass bei mir auch nichts geht.
    (Es wird überhaupt nichts übertragen. Noch nicht einmal ein Buchstabe.)
    Folgendes habe ich bis jetzt aber schon gefunden:

    Makefile:
    - MCU = atmega8 und nicht atmega32
    - F_CPU ist beim Asuro nicht 16000000, sondern nur 8000000
    - Dieses Makefile erzeugt einige, mir unverständliche, warnings

    main.c
    - Im bei dir fehlenden Init() wird das Interuptsystem in der CPU mit sei(); erst gestartet. Kann hier aber sein, das es nicht notwendig ist.
    - Im bei dir fehlenden Init() wird die Taktfrequence für den IR-Baustein gesetzt. Das fehlt bei dir.
    - Laut Band II, darf die Sendegeschwindigkeit nicht größer als 2400 Baud sein
    - Die Anzahl zu sendender Zeichen ist 13 und nicht 14 (\n und \r sind jeweils EIN Zeichen)
    - Am Ende fehlt ein "while(1);" vor dem return

    serial.h
    - "#define cBlockung 1" soll bestimmt cBlocking heißen

    serial.c
    - Es fehlt ein "#include <avr/signal.h>"
    - In "SIGNAL (SIG_USART_RECV)"
    --- " - 1 " fehlt im if
    - In "SIGNAL (SIG_USART_DATA)"
    --- "if (WritePointer0 > cWrite...." muß < haben
    --- //printf(WriteBuffer[WritePointer0++]); Ist zum Glück auskommentiert.
    --- Du würdest beim ausführen der Zeile auf alle Fälle den Zeiger WritePointer0
    --- mit dem da angehängten ++ um eine Stelle weiterzählen lassen.
    --- Das Zeug in einer Klammer () bei Funktionsaufrufen wird ausgeführt!

    Getestet habe ich auch die Variante, dass alles in einer Datei (test.c) steht und dann so wie im Band II laufen sollte. Geht bei mir aber aktuell auch nicht. Jetzt muss ich aber erst mal Schluß machen.

    P.S.: Klasse, dass du noch an's Makefile gedacht hast.
    Lieber Asuro programieren als arbeiten gehen.

    - In "SIGNAL (SIG_USART_DATA)"
    --- "if (WritePointer0 > cWrite...." muß < haben
    Und das war der Fehler. Er hat nie das Ende des Strings erreichen können, deswegen kam auch unendlich mal ein und dasselbe Zeichen. Ich hasse Tippfehler!

    Es ist schon richtig, ich habe her auch keinen Asuro sondern einen Atmega32 mit 16Mhz. Soweit stimmt das schon.
    Das Makefile habe ich mit MFile gemacht. Sollte eigentlich gehen.
    --- //printf(WriteBuffer[WritePointer0++]); Ist zum Glück auskommentiert.
    --- Du würdest beim ausführen der Zeile auf alle Fälle den Zeiger WritePointer0
    --- mit dem da angehängten ++ um eine Stelle weiterzählen lassen.
    --- Das Zeug in einer Klammer () bei Funktionsaufrufen wird ausgeführt!
    Ja, das war nur ein versuch mit einer anderen Funktion, um zu testen, wo der Fehler liegt, Sorry, habe ich nur vergessen zu löschen.
    - Am Ende fehlt ein "while(1);" vor dem return
    Wohl war, das mach ich schnell noch.

    Allerdings kommt auch bei mir nix mehr an. Aber der Cursor im HyperTerminal blinkt heftig. Also wrd irgendwas empfangen, nur was?

    Vielen Dank,
    Bääääär

    Oki, senden geht jetzt ohne Probleme. (es lag wohl daran, dass ich nur einmal gesendet habe (im programm) und das senden war schon vorbei, als ich das HyperTerminal aufgemacht hatte...). Aber empfangen geht noch nicht. Hier nochmal der ganze Code:
    Die serial.h bleibt gleich.

    serial.c:

    int main (void) {

    	RS232_init(9600);
    	while(1) {
    		RS232_receive(c, 1, cBlocking);
    		RS232_send("You typed: ", 11, cBlocking);
    		RS232_send(c, 1, cBlocking);
    		RS232_send("\n\r", 2, cBlocking);
    	}
    	return 0;
    }
    Nur damit erstmal alles hier oben ist, so wie es momentan funktioniert (und nicht funktioniert)

    Hallo Bääääär,
    bei mir geht das Empfangen auch nicht. (Umgestellt auf Asuro 2400 Baud, und includes)
    Ich kann aber keine weiteren Fehler entdecken.
    Für Heute gebe ich auf.
    Lieber Asuro programieren als arbeiten gehen.

    Hmm. Immerhin sagt mir das, dass der Fehler nicht im Aufbau meiner Schaltung liegt. Das ist doch schonmal erfreulich.
