GPIO plugin behaviour towards pullup / pulldown resistors

---

Hi,

Does anyone know if the gpio-plugin sets pullup/pulldown state on inputs??
When not, what would be the best way to set these?

@djazzz

try with “inverted”

{ 
  "id": "presence-sensor",
  "class": "GpioPresence", 
  "name": "motion detector",
  "gpio": 18,
  "inverted": true
}

so by changing to inverted, it sets pulldown-resistor?

and default there is a pullup?

@djazzz No, you need configure the pullup/pulldown resistors as part of the device tree setup

For example, see ee https://github.com/fivdi/onoff/wiki/Enabling-Pullup-and-Pulldown-Resistors-on-The-Raspberry-Pi

EDIT: Note beyond, with Raspberry Pi, most GPIOs have either their pull-up or pull-down resistor activated by default. The defaults can be seen in Table 6-31 on pages 102 and 103 of the BCM2835 ARM Peripherals documentation.

thanks !
