GPIO assignment

Hi,

next problem. I have looked in the code how the assignments are and have found the following:

Pin - Function
12 - Vol +
13 - Vol -
15 - next
16 - previous
11 - play / pause
03 - LED (outp.)

Is that correct?
And follow the numbers the physical pin numbering or assigning such as shown here?

Error "Object reference not set to an instance of an object"

Hi,

i have the program compiled with the VS 17 under Win7 and tried to run it on the PI with root.

I got the following error:

Autostart

--DE--

Moin Moin,

ich habe folgendes Problem, wie ich es auch drehe und wende, ich bekomme das Programm nicht in den Autostart. Zumindest nicht mit offenem Terminal, so das RFID-Cards eingelesen werden können.
Der Raspi startet mit der Grafischen Oberfläche und als PI eingeloggt.

Meine Frage nun, wie ist der Autostart gedacht? Oder ist es sogar erforderlich in der Konsole zu booten?

Vielen Dank schon einmal für die Hilfe.
MfG Jim

Good Day,

I have the following problem, I don't get the program the autostart. At least not with open terminal, that the RFID cards can be readed.
The Raspi starts with the graphical interface and logs in as PI.

My question, how is the Autostart thought? Or is it better to boot in the console?

Thanks a lot for the help.
MfG Jim
