[Huggi0619]

Hi Guys

I want to display a value at a gauge but it doesn't work and I can't figure out what the problem is.
Ist there anybody who can help me please? Wouldbe realy nice.
Here ist the code block from my arduino UNO R4 minima:

Code: Select all

    Serial.print("{Gau:IPGauge5|");
    Serial.print(linearSpeedKmh);
    Serial.println("}");
    ;

The propertiers of the gauge look like the pic in the attachment.

Thank you very much for your fast response and help
