Forum: Mikrocontroller und Digitale Elektronik Amtel Evaluationboard V2.01 - Programmieren mit WINAVR

Hallo,

ich möchte mit meinem Amtel Evaluationboard V2.01 den µC ATMEGA32 so 
programmieren, dass die beiden LEDs mit dem Taster 1 eingeschaltet und 
dann blinken und mit dem Taster 2 wieder ausgeschaltet werden sollen.

Jedoch kenn ich mich mit dem Programm WINAVR nicht aus um bräuchte mal 
Tipps, bzw. ne Beispieldatei, wie ich das  kann.
Bis jetzt habe ich eine Makefile-Datei angelegt und weiß jetzt nicht was 
ich genau einstellen, etc. machen muss.

Hab jedoch schon Probleme mit dem Makefile:

 "make.exe" all

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

to the

code to

done

Wieso nicht einfach mal die Suche bemühen und nach "no rule to make 
target" suchen?

hol dir avr studio von atmel
da schreibste das ganze in C,
jagst es durch den compiler,
dann rauf auf den AVR über ISP
mit ponyprog oder avrdude!

Wenn er sowieso das AVRStudio nutzt, kann er doch auch gleich über das 
AVRStudio den µC flashen?

Wenn eine aktuelle Version des AVRStudios das vom Threadstarter wohl als 
geläufig vorausgesetzte, aber zumindest mir unbekannte, generische "... 
Amtel Evaluationboard V2.01" unterstützt, dann ja, ansonsten wohl eher 
nicht.

Würde es sich dabei z.B. um das aktuelle Evaluationboard von Pollin 
handeln, dann geht es schon mal nicht.

Aufgrund der genannten Bezeichnung gehe ich davon aus,
dass es sich um das von Pollin vertriebene Evo Board handelt.
Dieses wird von Atmel AVR Studio 4.x nicht direkt unterstützt,
ist aber problemlos über die ISP mit einem geeigneten Programmer oder 
direkt über ne RS232 programmierbar!
Via USB/Rs232 Converter nicht zu empfehlen,
da extrem langsam!

Du möchtest also ein main.hex bauen (Der Ziel-Stamm soll 'main' heißen).

Und hier müssen die Quelldateien stehen. Aufgeführt ist main.c.  Gibt es 
die?  (Groß/Kleinschreibung muss stimmen.)  Vermutlich doch nicht.

      PORTD ^=  _BV(PD7);
      delay_10th_s(100);
      PORTD ^=  _BV(PD5);
      PORTD ^=  _BV(PD6);
      PORTD ^=  _BV(PD7);
      delay_10th_s(100);
      }
    return (0);
    }
}



nur habe ich probleme mit den eingängen also hauptsächlich PD2. das 
programm springt sofort in den else teil, aber sobald ich PD2 drücke 
springt dieser nicht in den if teil. woran liegt es???

Es liegt an der Nichtkenntnis der Abschnitte

des AVR-GCC-Tutorials
int main(void)
{
  // Einmalige Initialisierung
  DDRD &= ~(_BV(PD2)); // Eingang für Taster
  DDRD |= _BV(PD3); // Ausgänge...
  DDRD |= _BV(PD5);
  DDRD |= _BV(PD6);
  DDRD |= _BV(PD7);

  // Endlose Arbeitsschleife
  while(1)
  {
    if ((PIND & (1 << PD2))) // Liefert Taster HIGH an PD2?
    {
      // PD2 ist HIGH
      // Pollin-Boards mit active-high Taster: Taster ist gedrückt
      PORTD ^=  _BV(PD5);
      delay_10th_s(100);
      PORTD ^=  _BV(PD6);

    }
    else
    {

Danke für die Erläuterung, habe irgendwie PORTD hingeschrieben, obwohl 
ich ja PIND brauche -.- Naja. Aber jetzt klappt es, dankeschön für deine 
Tipps.
Dann werde ich mich mal an meine 12x12 LED-Matrix ranmachen.

Lerne lieber erst, mit dem Board umzugehen, bzw. den AVR  zu 
beherschen...
