AVR-Studio Simulator - EEPROM Auslesen bringt immer 0xFF
Moinsen.
Mal wieder ein Problem.
Für eine Aquariensteuerung (Mehrkanalschaltuhr etc.) schreib ich gerade das Programm. Die Hardware selbst ist noch nicht vorhanden, deshalb teste ich die Funktionen gerade im Simulator des AVR-Studio.
In diesem Programm sollen Werte für die Schaltzeiten im EEPROM abgespeichert werden. Beim Start des Programms sollen die Werte dann in Structs übernommen werden, die im RAM liegen.
Und genau da kommt das Problem: Aus noch unbekannten Gründen wird dort immer 0xFF ausgelesen.
Dabei ist es egal, welche der drei folgenden Aufrufe ich verwende:
Code:
Channel[CH1].TH_Off = EEP_ReadByte(S_T1_OFFH);
Channel[CH1].TH_Off = EEP_T1_OffH;
Channel[CH1].TH_Off = EEP_ReadByte(EEP_T1_OffH);
Ich hab mal die betreffenden Dateien hier angehängt. Das gesamte Projekt liegt in nem .zip-Archiv ebenfalls mit dabei. Nicht wundern über die ganzen anderen "Baustellen".
Sieht hier jemand den Fehler?
Oder ist das wieder eines dieser Dinge, wo der Simulator einfach Mist baut?
