/*
  SPS System mit dem Arduino.
  Version 0.10
  18.11.2018 WKLA
  - new standard programming mode
  i added a new programming mode for the default programming, because i thing the old one was a little bit clumsy.
  the new one has a nicer interface, as you now always know where you are.
  Starting with PRG pushed after Reset.
  as a result, all LEDs will shortly blink
  now you are in programming mode.
  * the D1 LED will blink
  * the higher nibble of the address will be shown
  * the D2 LED will blink
  * the lower nibble of the address will be shown
  * the D3 LED will blink
  * the command part (high nibble) will be shown
  * with SEL you can step thru all commands
  * PRG will save the command
  * the D4 LED will blink 
  * the data part (low nibble) will be shown
  * with SEL you can step thru all datas
  * PRG will save the data
  * if the new value has been changed, all LEDs will flash as the byte will be written to the EEPROM
  * address will be increased and now it will start with blinking of the D1 LED
  * 
  * To leave the programming simply push reset.
  

  Version 0.9
  18.11.2018 WKLA
  - BUGs entfernt. Release.
  10.11.2018 WKLA
  - Implementierung Tone Befehl

  Version 0.8
  06.11.2018 WKLA
  - Umstellung auf dbgOut
  - Display TM1637 Anbindung

  Version 0.7
  24.09.2012 WKLA
  - neue Berechnung A = B - A und Swap A,B...
  - Stack auf 16 Bytes berschränkt, wird zu oft gepusht, werden die alten Werte rausgeschoben.

  Basierd auf dem TPS System vom elektronik-labor.
  Erweiterungen:
  - es können bis zu 6 Unterroutinen definiert werden und diese direkt angesprungen werden.
  - neben return gibt's auch einen restart
  - 2 Servoausgänge für übliche RC Servos. (10° Auflösung in Nibble Modus, <1° Auflösung im Bytemodus)
  ACHTUNG: Servo und PWM Ausgänge sind nicht mischbar und können auch nicht gleichzeitig benutzt werden.
  - 2 RC Eingänge (16 Schritte auflösung im nibble Modus, Mitte 8, 255 Schritte im Byte Modus)
  - fkt. auch mit einem ATTiny84 (44 ist leider auf GRund der Programmgröße nicht mehr für den erweiterten Befehlssatz möglich)
  - call stack von bis zu 16 Unterfunktionen
  - neue Register e,f
