Wenn ich es richtig sehe liegt der Fehler in der Initialisierung des richtigen Pi. Der Fehler läuft also in der Abfrage in der Datei gpioControl.js in den Fehler.
Pi kleiner 5 sollte hier also gpio Chip 0 sein. ansonsten 4.
Vielleicht sieht hier einer von euch das Problem: Zeile 9 liest er das Model aus, oder versucht es aus der Info:
der Befehl
cat /proc/cpuinfo
ergibt bei mir in der letzten Zeile:
"Model : Raspberry Pi 3 Model B Rev 1.2"
was hier anscheinend abgefragt wird - mal ein Ausschnitt aus der Datei - am Ende unsere Fehlermeldung:
function getRaspberryModelFromCpuInfo(cpuinfo) {
//Zero reports: Raspberry Pi Zero 2 W Rev 1.0
// RPi Zero family has a different naming.
// All Rpi Zero share the same ChipNum as RPi 1 and thus can all be handled as a Rpi 1.
if (cpuinfo.includes('Zero')) {
return 1;
}
const modelRegEx = /^Raspberry Pi (\d+) Model.*/mi;
const model = modelRegEx.exec(cpuinfo)[1];
return Number(model);
