ATMega128A, mehrer getestet PD0 und PD 1 gehen nicht

[Rene H. (ballibou77)]

Hallo,

ich versuche nun seit gestern Mittag einen TWI Master mit einem 
ATMega128A aufzusetzen.

Ohne erfolg.

Also, Ätzbad an, neue Platine gefertigt, neuen ATMega128A aufgelötet, 
ordentlich Flux und getestet.

Nichts.

PD0 und PD1 lassen sich nicht schalten (TWI)

Also, Testcode aufgesetzt:

#include <avr/io.h>
#include <util/delay.h>

int main(void)
{    

DDRC |= (1<<PC0);


DDRD |= (1<PD0);
DDRD |= (1<PD1);


  while(1)                            
    {  
      PORTD &= ~(1<<PD0);
      PORTD &= ~(1<<PD1);
      PORTC &= ~(1<<PC0);
      _delay_ms(500);
      PORTD |= (1<<PD0);
      PORTD |= (1<<PD1);
      PORTC |= (1<<PC0);
      _delay_ms(500);
    }
}

Oszi an PC0 und? tada

Oszi an PD0 und? nichts
Oszi an PD1 und? nichts

Gelesen, gelesen gelesen, aha, M103 fuse. Also Fuses neu gesetzt (siehe 
Screenshots).

und? Nichts.

Ich bekommen an den PINs PD0 und PD1 keinen takt. Egal was ich mache. 
Ich habe den ATMega128 dann ausgelötet. Den dritten ATMega128 
aufgelötet, das selbe.

Ob mit externem Quarz oder ohne. Mit M103 Fuse oder ohne. Die PINs PD0 
und PD1 wollen absolut nicht.

Das Hardware TWI lässt sich ja nicht umstellen auf andere PINs.

Was kann es sein?

> DDRD |= (1<PD0);
> DDRD |= (1<PD1);
Nanu?

Für richtigen Prozessor kompiliert?

∗hüstel∗ ..Leerzeichen regeln.. oder hier alternativ auch _BV()..

[Rene H. (ballibou77)]

Ja, hab eich auch gerade gesehen, angepasst also mit 2 << und trotzdem. 
immernoch das selbe. Die PINs bleiben im HIGH zustand.

[Felix Adam (Gast)]

Machen die anderen Portpins an Port D denn etwas, wenn die als Ausgang 
geschaltet werden und du z. B. 0xFF in PORTD schreibst?

[Rene H. (ballibou77)]

Hallo,

ja das habe ich vergessen anzumerken. Ich habe mittels Oszi alle PINs 
durchgetestet. Hatte ja Zeit, die ganze Nacht bis jetzt. Kein erfolg. 
ALLE PINs am µC lassen mich einen Takt erzeugen. Sich hin und her 
schalten etc. pp.

Nur PD0 und PD1 nicht. Und das bei 3 ATMega128A das kann doch nicht 
sein. Habe hier eine "Produktionspackung" aber ich will nicht unbedingt 
alle 120 aus und ein löten.

[Karl H. (kbuchegg)]

Blöde Frage.
Externen Kurzschluss kannst du ausschliessen?

[Einhart P. (einhart)]

Wenn du Hardware TWI nutzt, dann wirst du die Port-Pins nicht über 
normale I/O Befehle ansprechen können:

Aus dem Datenblatt:

"When the TWEN bit in TWCR is set (one) to enable the Two-wire
Serial Interface, pin PD1 is disconnected from the port and becomes the 
Serial Data I/O pin for the Twowire
Serial Interface."

Für PD0 gilt dasselbe.

[Felix Adam (Gast)]

Das hat der TE in dem Testcode ganz oben ja auch nicht gemacht.

[Rene H. (ballibou77)]

Hallo,

ich habe sogar heute mittag die Platine komplett neu gefertigt und 
erneut zusammen gelötet. Weil ich teilweise verrückt geworden bin habe 
ich dann jede einzelne Leiterbahn geprüft, also mit Durchgangsmessung ob 
ein Kurzschluß vorliegt. Nichts gefunden. Mit ner Lupe die Lötstellen 
angesehen. Nichts.

Also entweder sie die alle Defekt (Montagsproduktion) die mögen mich 
einfach nicht.

Ja, bei TWI ist das klar, nur siehe oben, es läuft nur ein "testcode" 
noch nichts mit TWI oder sonst was.

Für den Fall das wir uns hier einig sind und sagen "defekt" kann ich die 
"tauschen"?

Also das war jetzt eine Nagelneue Industrieverpackung. Also frisch 
geöffnet. Das ist das erste mal das ich Teile von RS beziehe und das 
sowas -.-

Mit vorherigen ATMega128 aussem eBay einfach in einem Briefumschlag und 
in Zewa eingewickelt hatte ich bislang keine Probleme.

Aber 120 Stück kaputt kann ich mir auch kaum vorstellen.

[Einhart P. (einhart)]

Hast du 'mal das TWCR Register im Testcode entsprechend gesetzt?

[Felix Adam (Gast)]

Es gab neulich schonmal jemanden, bei dem diese beiden Pins gesponnen 
haben. Er hat auch mal probiert, den Port auf Eingang zu stellen und die 
Pullups anzuschalten, woraufhin an PD0 und PD1 eine Spannung zu messeh 
war.
Ist das hier vielleicht auch der Fall?

[Rene H. (ballibou77)]

So, ich habe ihn jetzt ausgelötet und mal einen ATMega128A aus der mitte 
der Packung genommen. Und siehe da. Es geht.

Also sage ich jetzt einfach mal, die sind defekt. Also ATMega128A Nr. 71 
funktioniert tadellos.

Was mache ich nu? Alle testen? Die defekten nach Atmel schicken?

[OldMan (Gast)]

Nee, zum Distri von dem Du Dinger erhalten hast. Oder sind die aus 
China?
Wenn die Quelle China ist: Lehrgeld bezahlt. Mülltonne auf und rein 
damit.

Vielleicht an PDO und PDI gemessen?

[xlomx (Gast)]

Ich bin mal über diesen Atmega102 Kompatibilätsmodus gestolpert. Der ist 
sicher aus?
