Ok, also nach ewigem rumprobieren werd ich jetzt dann doch mal eine Frage stellen, auch wenn sie wahrscheinlich relativ dumm ist.
Ich habe gestern meinen ATmega16 angeschlossen und versucht zu programmieren (winAVR + ponyprog). Die Übertragung des Programms scheint zu funktionieren, denn die Verifizierung der Daten nach der Übertragung hat nix zu meckern. Mein letztes Program sah so aus, dass ich einfach Port A-C komplett als Ausgänge gemacht habe und auch alle auf 1 (hoffe ich doch, habe aber auch schon alles auf 0 probiert usw).


#include <avr/io.h>

int main(void)
{
DDRC = 0xFF;
PORTC = 0xFF;
DDRB = 0xFF;
PORTB = 0xFF;
DDRA = 0xFF;
PORTA = 0xFF;

while (1)
{

}
return 0;
}

Ich habe rundrum überall 0V an den "Ausgängen"... Als ich mal JTAG aktiviert hatte, hat mir das aber Spannung geliefert an den PINS C2,3 u 5, so wie es sein soll, also ganz kaputt kann das Teil nicht sein.
Da dies mein erster uC ist und ich auch bisher nicht wirklich viel Ahnung habe, ist es schon deprimierend, dass es jetzt an einer läppischen LED scheitern soll. Ich denke, ich sollte einen anderen uC probieren (ich habe noch 2 ATtiny26 rumliegen). Vielleicht habe ich ja schon den ersten auf dem Gewissen... :(
Hat irgendwer nen Tipp, wie ich irgendwie rausfinden kann, ob ich das Teil nun in die Tonne treten kann, oder doch vielleicht nur irgendwas falsch gemacht hab? Wenn es wenigstens 1x funktioniert hätte, dann könnte ich ausschliessen, dass es an meiner Programmierung (die ja wirklich ned soo schwer ist) oder an meinem Programmer liegt... Noch sind es zu viele Unbekannte. Ich hatte die Probleme etwas später erwartet.
Kann man annehmen, dass wenn man das Ding fehlerfrei programmieren kann, dass dann auch normalerweise auch das Programm ablaufen sollte?
Oder muss man das Programm noch irgendwie starten? Ich dachte gehört zu haben, dass das von alleine losläuft, sobald der Reset nach dem Programmieren wieder weg is...

Auf meinem 90S8515 läuft das Programm einwandfrei, nen Fehller seh ich so spontan auch nicht...

hier mal ne etwas dynamischere Version:


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

void warte(int loop) //loop: wartezeit in ms
{
int i;
for(i=0;i<loop;i++) _delay_ms(1);
}

int main(void)
{
DDRC = 0xFF;
DDRB = 0xFF;
DDRA = 0xFF;

for (;;)
{
PORTB = 0xFF;
PORTA = 0xFF;
PORTC = 0xFF;
warte(400);
PORTB = 0x00;
PORTA = 0x00;
PORTC = 0x00;
warte(400);
}
}


kompiliert wird aber richtig, oder? makefile korrekt?

zur Sicherheit nochmal die .hex für nen Mega32:

Vielen Dank schonmal für die Hilfe. Meine Vermutung war auch schon das Makefile, da ich mit sowas noch keinerlei Erfahrung habe.
Ich kann es mal posten, ich habe es mit diesem Makefile-Generator von winAVR gemacht.

Also bis auf ein paar ganz kleine Abweichungen sieht das schon gleich aus... Ich weiss nicht, könnte vielleicht daran liegen, dass das hier für den ATmega 16 ist (obwohl die ja ned arg anders sind, oder?).
EDIT: Oh, noch was ist mir aufgefallen:
Warum ist das, was mir in PonyProg angezeigt wird, nicht dasselbe wie das, was ich im .hex-File sehe? Ist das normal so?

funktionierts denn jetzt?
Leider nein ](*,)
Ich habe rundrum an allen pins, die nicht an den Programmer oder VCC angeschlossen sind, ziemlich genau 0V. :/
Ich denke es hat fast keine Sinn mehr weiterzumachen. Ich werde jetzt glaube ich mal den ATtiny auspacken und damit testen ob ich was zum Laufen bring. Hätte ich nur einen zweiten mega16 gekauft, dann könnte ich jetzt prüfen, obs an der HW liegt :|


EDIT:
*andenkopfklatsch*
Ok, ich habe nochmal alle Kabel rausgerissen und neu reingestopft, daran hat es aber bestimmt nicht gelegen. Ich hatte aber blöderweise eine LED beim RESET dran, um zu sehen, wann das proggen fertig ist. Irgendwie wird die aber leider meinen uC dazu gebracht haben zu denken, dass er immer resetted wird :/ (oder was anderes aber mein elektronisch unwissendes Hirn erklärt sich das jetzt so...)

Danke an alle, die sich die Zeit und Mühe gemacht haben mir zu helfen. Jetzt kanns endlich losgehen :)
