Szia, köszi a segítséget!

A setNumber bejött, most viszont a void smartDelay-ben levő PrintOutput-ra írja hogy has no member in sevseg. Az ino-ban pirossal van írva a hibaüzenet tárgya.

Ami azért érdekes,mert a void loop-ban is van egy sevseg.PrintOutput és azon átsiklott.

Te érted ezt? Csatolom az eddigiek figyelembe vételével átírt ino-t:

#include "SevSeg.h"
#include "TinyGPS++.h"

//Instance aanmaken voor GPS en Display
SevSeg sevseg;
TinyGPSPlus gps;

//int Snelheid variable vullen
int Snelheid=88;

void setup() {
     byte numDigits = 2;
     byte digitPins[] = {A2, 5};
     byte segmentPins[] = {6, 7, 4, A3, A4, A1, A0, A5};  
     sevseg.begin(COMMON_ANODE, numDigits, digitPins, segmentPins);
     sevseg.setBrightness(50);
     Serial.begin(9600);  
}

void loop()
{
  Snelheid = (gps.speed.kmph());
  sevseg.setNumber(Snelheid,0);  
  sevseg.PrintOutput();
  smartDelay(10);
}


void smartDelay(unsigned long ms)
{
  unsigned long start = millis();
  do
  {
    while (Serial.available())
      gps.encode(Serial.read());
      sevseg.PrintOutput();
  } while (millis() - start < ms);
}

void printFloat(float val, bool valid, int len, int prec)
{
  if (!valid)
  {
    while (len-- > 1)
    displayNumber(0000);
      Serial.print('*');
    Serial.print(' ');
  }
  else
  {
    Serial.print(val, prec);
    int vi = abs((int)val);
    int flen = prec + (val < 0.0 ? 2 : 1); // . and -
    //flen += vi >= 1000 ? 4 : vi >= 100 ? 3 : vi >= 10 ? 2 : 1;
    flen += vi >= 10 ? 2 : 1;
    for (int i=flen; i<len; ++i)
      Serial.print(' ');
      displayNumber(val);
  }
  smartDelay(0);
}

void displayNumber(int toDisplay) {

  //for(int digit = 4 ; digit > 0 ; digit--) {

    }

    //Turn on the right segments for this digit
    lightNumber(toDisplay % 10);
    toDisplay /= 10;

    delayMicroseconds(DISPLAY_BRIGHTNESS); //Display this digit for a fraction of a second (between 1us and 5000us, 500 is pretty good)

    //Turn off all segments
