Changing GPIO behaviour in (

Thu Jul 19, 2018 4:23 pm


I am using together with the GPIO Plugin on my Raspberry to drive the ... pi_program through the WebInterface. It's working fine except for the default GPIO defination.

The Relays are are low active and when I reboot my Raspberry they are in the OFF Position.
As soon as I define the GPIO's in Picontrol GPIO Plugin the Relays close. See attachment "Relays Closed.JPG"

Waveshare wiki says this: "When the Raspberry Pi outputs Low Level from its IO, the LED related to the corresponding channel lights up. At the same time, the relay NO (normally open contacts) closes."

But for my project I need them to stay in the normally open state, I had a similar with a previous project where I user WebIOPi and there I had the config file where I could define the state for Startup.

for I didn't manage to find the config for the GPIO
I need to change the behaviour so that the GPIO Plugin start the Relays in the low active state. see attachment "Relays Open.JPG"

is there someout around who can help me?
