Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

NAME
gpioctl -- GPIO control utility
SYNOPSIS
gpioctl -l [-f ctldev] [-v] gpioctl -t [-f ctldev] pin gpioctl -c [-f ctldev] pin flag [flag ...] gpioctl [-f ctldev] pin [0|1]
DESCRIPTION
The gpioctl utility could be used to manage GPIO pins from userland and list available pins. The options are as follows: -c pin flag [flag ...] Configure pin by setting provided flags. The following flags are currently defined: IN Input pin OUT Output pin OD Open drain pin PP Push pull pin TS Tristate pin PU Pull-up pin PD Pull-down pin II Inverted input pin IO Inverted output pin -f ctldev GPIO controller device to use If not specified, defaults to /dev/gpioc0 -l list available pins -t pin toggle value of provided pin number -v be verbose: for each listed pin print current configuration
EXAMPLES
o List pins available on GPIO controller defined by device /dev/gpioc0 gpioctl -f /dev/gpioc0 -l o Set the value of pin 12 to 1 gpioctl -f /dev/gpioc0 12 1 o Configure pin 12 to be input pin gpioctl -f /dev/gpioc0 -c 12 IN
