Problem mit ATMEGA162 - PORTC.4; 5; 6; 7 funktioniert nicht
Hallo,
es geht eigentlich noch um die Stellpultsteuerung aus dem Thema "Zähler". Ich habe folgendes Problem:
Die Ausgänge (PortC.4; PortC.5; PortC.6; PortC.7) vom "ATMEGA162 16PU 0908H" funktionieren nicht. An den Ausgängen hängen Transistoren, die die Weichen schalten. Wenn ich den µC aus der Schaltung nehme und eine Drahtbrücke von +5V auf die jewailigen Pins tippe schalten die Weiche. Dann habe ich den µC in das STK500 geschteckt und ein kleines Testprogramm geschrieben wobei die LEDs blinken sollten. PortC.0 bis PortC.3 haben auch wie gedacht funktioniert, nur die LEDs von PortC.4 bis PortC.7 haben weder geleuchtet noch geblinkt.
Alle anderen Pins des µC arbeiten wie gewünscht.
Ein zweiter µC hat das selber Ergebnis gerbracht.
Wo liegt der der Fehler?
LG Felix
Ich kenne diesen Kontroller nicht, aber vielleicht haben diese Pins eine Sonderfunktion und müssen erst über spezielle Register zu Ausgangspins umgeschaltet werden?
Kannst du mal den Quellcode posten?
Also, das aktuelle Programm sieht folgendermaßen aus:

Das Programm ist sicherlich nicht optimal Programmiert, ich komme in dieser Art und Weise relativ gut klar

Hallo Felix!
Diese Pins sind mit dem JTAG-Interface vorbelegt. JTAG musst du über die Fuse-Bits deaktivieren. Dann läuft es.

Hallo Felix!
Laut Datenblatt hat der ATmega162 1024 Byte SRAM. Davon verbrauchst du mit den von dir gezeigten Anweisungen ca. 150 %.
Du hattest bis jetzt nur Glück, dass du noch keine Variablen und Prozeduren gebraucht hast -- sonst wäre dein Programm irgendwie unkontrollierbar im Speicherwirrwarr abgesoffen.
Stelle HWSTACK, SWSTACK und FRAMESIZE auf jeweil 100 zurück. Damit hast du viel mehr als genug -- auch für große Projekte.

Hallo Gerold,
vielen Dank für deine Schnelle Nachricht. Ich habe noch 2 Fragen:
- Was ist ein JTAG-Interface?
- Wie und wo kann ich (der/die/das) JTAG über die Fuse-Bits deaktivieren
LG Felix
Edit: ich werde deinen letzten Beirag beherzigen
| modellfreund hat folgendes geschrieben: |
| - Was ist ein JTAG-Interface? |
Hallo Felix!
Kurz gesagt: Es ist wie die ISP (In System Programming) Schnittstelle, eine Möglichkeit, das Programm vom Computer zum µC zu übertragen. JTAG hat den Vorteil, dass man damit das Programm zusätzlich auch debuggen (sozusagen, beim Laufen beobachten) kann. Das ist für Assembler oder C-Programmierer manchmal nicht schlecht, für Bascom-Hardcore-Programmierer vielleicht mal interessant, aber für dich und mich absolut unwichtig und kann gefahrlos deaktiviert werden.
| modellfreund hat folgendes geschrieben: |

Mit welchem Programm änderst du die Fuse-Bits?
Lesestoff: http://halvar.at/elektronik/kleiner_bascom_avr_kurs/ Kapitel 22, 23, 24
Eine genaue Anleitung für den ATmega162 kann ich dir nicht geben. Ich habe weder einen ATmega162, noch im Moment irgend ein Elektronik-Programm auf meinem Computer installiert.

Zu der Frage was ein JTAG-Interface ist (ich wusste es ehrlich gesagt auch nicht so genau): http://de.wikipedia.org/wiki/JTAG
Das umstellen der Fuse Bits sollte mit dem Programm geschehen, mit dem du deinen Code auf den µC bringst. Ich habe nur in C programmiert und mit PonyProg2000 gab es da jedenfalls ein extra Menü.

Ups, da war gerold schneller^^

Das ist der Standardfehler " Datenblatt nicht gelesen "
