Ich versuche eine Lib zu schreiben, deren Klasse mit mehreren Instanzen benötigt wird. Da die Instanzen keine statischen variablen besitzen, sollten die Werte unabhängig voneinander persistent sein. Leider ändern sich meine Werte nicht.
Diese Lib ist mein ertser Versuch. Libs in Arduino selbst zu basteln:
.*h File
Code:
#ifndef SystemTools_h
#define SystemTools_h
#include <Arduino.h>
class SystemTools{
private:
unsigned long _onOffCountB;
unsigned long _onOffCountB_Tmp;
unsigned long _ET;
bool _startTmp;
unsigned long _onOffCountP;
unsigned long _onOffCountP_Tmp;
public:
SystemTools(){;};
// ++++++++++++++++++ raising edge ++++++++++++++++++++++++++++
bool R_Trigg(bool start);
// +++++++++++++++++++++++++ Timer On Delay +++++++++++++++++++++++
bool TimerOnDelay (bool start, unsigned long PT,unsigned long TimeStamp);
// +++++++++++++++++++++++++ Blink +++++++++++++++++++++++
bool Blink (unsigned long PtHalf,unsigned long TimeStamp);
// +++++++++++++++++++++++++ Blink Pulse+++++++++++++++++++++++
bool BlinkPulse (unsigned long PtHalf,unsigned long TimeStamp);
};
#endif
.*cpp File
Code:
#include <Arduino.h>
#include <SystemTools.h>
// ++++++++++++++++++ Constructor ++++++++++++++++++++++++++++
//SystemTools::SystemTools();
// ++++++++++++++++++ raising edge ++++++++++++++++++++++++++++
bool SystemTools::R_Trigg(bool start)
{
if (!start){
_startTmp = false;
return false;
}
if (start &! _startTmp){
_startTmp = true;
return true;
}
else
{
return false;
}
}
// +++++++++++++++++++++++++ Timer On Delay +++++++++++++++++++++++
bool SystemTools::TimerOnDelay (bool start, unsigned long PT,unsigned long TimeStamp){
if (R_Trigg(start)){
_ET = TimeStamp;
}
if(!start) {return false;}
return ( (_ET+PT-5) < (TimeStamp) ) ? true : false;
// -number for cycle delay
}
// +++++++++++++++++++++++++ Blink +++++++++++++++++++++++
bool SystemTools::Blink (unsigned long PtHalf,unsigned long TimeStamp){
if (TimerOnDelay(_onOffCountB == _onOffCountB_Tmp, PtHalf/2, TimeStamp ) )
{
_onOffCountB++;
}
else{
_onOffCountB_Tmp = _onOffCountB;
}
if(_onOffCountB%2){
return true;
}
return false;
}
// +++++++++++++++++++++++++ Blink Pulse+++++++++++++++++++++++
bool SystemTools::BlinkPulse (unsigned long PtHalf,unsigned long TimeStamp){
if (TimerOnDelay(_onOffCountP == _onOffCountP_Tmp, PtHalf, TimeStamp ) )
{
_onOffCountP++;
Serial.println("RE:" + String(TimeStamp));
return true;
}
else{
_onOffCountP_Tmp = _onOffCountP;
//Serial.println("NOT:" + String(TimeStamp));
}
return false;
}

WS2801_M::color buf[pixel] = {0};

ws1.Glow(&buf[0], false, (systemTools1.BlinkPulse(20, TimeStamp))); //trigg

}
[b]Interessant ist, dass die lib SystemTools korrekt funktioniert, dh dass es da keine Probleme mit dem inkrementieren der Variablenwerte gibt.
Natürlich freut mich neben Lösungsvorschlägen auch, wie man den Code weiter verbessern sollte.
