Bascom State Machine Menu
Beim der Umsetzung des Beispielcodes von Atmel für AVR Butterfly [[1]] (in IAR-C bzw. die GCC-Portierung) nach Bascom [[2]] entstand folgende hoch effiziente State Machine zur Umsetzung eines Menüs für einen Datalogger.
Der Code wurde hier stark reduziert, so dass vom gesamten Programm das Menü als Rahmen mit allen Unterprogrammen (leer) übrig geblieben ist.
Die Menü-Struktur
Als Beispiel wird hier die um die Umsetzung des Menüs aus dem AVR Butterfly Evaluation Kit in Bascom gezeigt:
Sample Code Variante 1: unübersichtlich und wenig Code
Der Code ist die 1:1 Umsetzung des C-Codes aus dem AVR Butterfly Evaluation Kit. Das Code-Beispiel wurde für den Bascom Simulator optimiert und kann dort direkt mit den Ziffern-Tasten bedient werden (NumLock!). Auf dem Simulator-LCD-Display werden die Ebenen mit angezeigt (3 -> 31 -> 32 -> 321 etc.)
Getestet im Bascom-Simulator der Versionen:
- BASCOM 1.11.9.1 [OK]
- BASCOM 1.11.8.7 [Probleme mir der LCD Darstellung]
- BASCOM 1.11.8.1 [OK]
Die Codelänge des Samples beträgt ca. 2300Byte. Der größte Teil geht für die LCD-Anzeige, Anzeigetexte etc. drauf. Der State Machine selber ist sehr schlank, da nur Pointer (Zeiger) gesetzt werden.
Weitere Erklärungen stehen im Quelltext.

Sample Code Variante 2: übersichtlich und viel Code
Die Variante 1 ist leider unübersichtlich, da 3 Tabellen getrennt geführt werden (die State Machine, die Menütexte und die zugehörigen Unterprogrammeinsprünge). Nachfolgend eine Variante, in der nur eine Tabelle (Select Case State...) geführt wird. In jedem Statement Blocks steht ein Menütext (falls erforderlich), der Pointer für den Unterprogrammeinsprung (falls erforderlich) und ein Datensatz für die Verzweigung der State Machine (zwingend erforderlich).
Die Codelänge des Samples beträgt jetzt immerhin 3300Byte anstatt der 2300Byte von Variante 1. Dafür ist das Menü deutlich einfacher zu editieren.
Weitere Erklärungen stehen im Quelltext. Die Bedienung erfolgt wie bei Variante 1.
