Bascom State Machine Menu
Beim der Umsetzung des AVR Butterfly IAR-C Code (bzw. der GCC-Portierung) nach Bascom [[1]] entstand folgende hoch effiziente State Machine zur Umsetzung eines Menüs für einen Datalogger.
Der Code wurde stark reduziert, so dass für das gesammte Programm der Menü-Rahmen mit allen Unterprogrammen übrig geblieben ist.
Die Menü-Struktur
Sample Code
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.)
Weitere Erklärungen stehen im Quelltext.
'Beispiel für ein State Machine Menü
'Das Beispiel ist für den BASCOM-Simulator angepasst worden
' getestet mit BASCOM 1.11.8.1
' Codelänge 2362 Byte

'Hinweis: Im Simulator müssen die Eingaben in das "Terminal Emulator Window" erfolgen!
