== Overview ==
* COMEX-IC60U supports Linux Mint 18 LTS with full-featured desktop environment
* All necessary drivers and tools are already installed
* Networking, sound, video acceleration, 2D and 3D graphics and other features work out of the box
<br>

== Display Interfaces ==
* By default HDMI output is enabled and eDP output disabled in the Linux package
* To enable eDP output need to remove "video=eDP-1:d" kernel boot option from /boot/grub/grub.cfg and /etc/default/grub
<br>

* The GPIO sysfs interface allows users to manipulate any GPIO from userspace dynamically.
* A basic example of GPIO 417 Pin B57 (P26-6 on SB-COMEX) usage as root user:

$ echo 417 > /sys/class/gpio/export
$ echo out > /sys/class/gpio/gpio417/direction
$ echo 1 > /sys/class/gpio/gpio417/value
## at this point voltage measuring on B57 (or P19-6) should give 1.3V
$ echo 0 > /sys/class/gpio/gpio417/value
## at this point voltage measuring on B57 (or P19-6) should give 0.0V
$ echo 417 > /sys/class/gpio/unexport

* The GPIO framework and GPIO sysfs interface are documented in https://www.kernel.org/doc/Documentation/gpio/gpio.txt
