GPIO default on HIGH

[pfichtner]

For which GPIO pin? This one?

"name": "switch_gpiopin",
"label": "GPIO Pin switched HIGH when button press detected"

[pfichtner]

Please give https://github.com/pfichtner/SipDoorbell/releases/tag/0.1.2 a try

[Kunstflieger]

Thanks for this fast support!
I mean this one:
"label": "GPIO Pin to connect a push button which triggers a call"

If I enter Pin e.g. "2" than it starts to ring until GPIO 2 is connected to ground (always closed). I want to use start ringing if GPIO 2 is connected to groun (always open).

Reopened since the fix doesn't solve the problem, will fix later

In my configuration I connected the push button to the digital pin and VCC, will have a look if I'll support your setup as well and how.

[pfichtner]

@Kunstflieger so which setup do you use?
https://kalitut.com/raspberrypi-gpio-pull-up-pull-down-resistor/
I am using variant 4 so the pin get's high when the switch gets closed. If I understand you right your schematic is variant 3? So you want to have support for this variant, right?

[pfichtner]

@Kunstflieger Would you also have the need for support for the internal pullup?

[Kunstflieger]

I didn´t used a Pull-UP resistance. Just GPIO --> GND. So it makes sense to us a Pull-UP resistor and I will test it today.

[pfichtner]

@Kunstflieger I added support for pullup and pullup-internal as well.
Please download and flash firmware.bin of https://github.com/pfichtner/SipDoorbell/actions/runs/5870078571

Now you can configure the input mode

Mode	Description
PULLUP	Initiate call if input gets low, no internal pullup resistor
PULLUP (internal)	Initiate call if input gets low, internal pullup resistor
PULLDOWN	Initiate call if input gets high

Haven't tried the image on my own, yet

Unfortunately no response from OP @Kunstflieger: Will close it without the knowledge if the PR fixes OP's problem or not
