ShiftOut mit mehr als 16 Bit

International Deutsch
1

Hallo
Ich versuche diese Prozedur auf 48 Bit auszuweiten bekomme es aber einfach nicht und erbitte nun eure Hilfe.
Das ist das was ich im Moment habe ,was auch einwandfrei funktioniert.

unsigned int sequence0[16] = {
  0x0,0x1,0x2,0x4,0x8,0x10,0x20,0x40,0x80,0x100,0x200,0x400,0x800,0x1000,0x2000,0x4000};

unsigned int sequence1[16] = {
  0x0,0x1,0x3,0x7,0xf,0x1f,0x3f,0x7f,0xff,0x1ff,0x3ff,0x7ff,0xfff,0x1fff,0x3fff,0x7fff};

digitalWrite(latchPin, LOW);

      shiftOut(dataPin, clockPin, MSBFIRST, B00000000);  
      shiftOut(dataPin, clockPin, MSBFIRST, B00000000);  
      shiftOut(dataPin, clockPin, MSBFIRST, B00000000); 
      shiftOut(dataPin, clockPin, MSBFIRST, B00000000); 
      shiftOut(dataPin, clockPin, MSBFIRST, sequence0[encoder0Pos]>>8);
      shiftOut(dataPin, clockPin, MSBFIRST, sequence0[encoder0Pos]);

    digitalWrite(latchPin, HIGH);

Das sequence 0 und 1 dann später mehr Daten beinhalten müssen ist klar ,mir gehts nur um die Ausgabe per shiftOut.

Vielen dank für eure Mühe und Zeit im vorraus

Wenn es geht, wo ist dann das Problem genau?

32 Bit bekommt man in einen unsigned long. Das kann man dann einfach >> 16 und >> 24 schieben. Weiß nicht wo du die anderen Bytes herbekommst.

Die Hardware kann bei 6 SR auch Probleme machen. 100nF Abblockkondensatorn an jedem IC nicht vergessen! SPI zu verwenden wäre auch nicht verkehrt.

Vielen Dank für die Antwort .
Funktionieren tut es einwandfrei mit 16 bit .
die 100 nf pro ic ist klar .

Darum geht es :

So ich habe es nun anders gelöst. Für die es Interessiert oder nach sowas googlen und nix finden.

  0x0,0x1,0x3,0x7,0xf,0x1f,0x3f,0x7f,0xff};

Danke für die anreize.
