<H2>HiPi PUD Utility</H2><p>The <A HREF="mod_gpio_bcm2835.htm">HiPi::BCM2835</A> module provides access to functions that allow you to set the pull up / pull down resistors on the GPIO pins</p>
<p>The hipi-pud utility is provided to allow access to this facility when not running under sudo and to support the setting of resistors in <A HREF="hipi-device-gpio-pin.htm">HiPi::Device::GPIO::Pin</A></p>
<p>The calling process user must be a member of the group <B>gpio</B> to execute the utility.</p>
<p>You can manage group membership with the <A HREF="control_app_gpio_device.htm">HiPi Control Gui</A>.</p>
<h3>Command Line Help</h3><pre>
usage : hipi-pud PINID SETTING
PINID = bcm2835 gpio pin number
SETTING = c[lear] | u[p] | d[own]
Examples:
clear pull up /down resistors for GPIO 24
hipi-pud 24 clear
set pull up resistor on GPIO 24
hipi-pud 24 up
set pull down resistor on GPIO 24
hipi-pud 24 down
Note: PUD settings cannot be read or queried
and last across restarts.
