Hello.
I run carpi on Raspberry Pi 2 B, 5inch HDMI LCD , 800 × 480 touch on the controller ads7846 . Unfortunately, the touch interface is controlled by gpio and I have a problem with connecting controllers and radio fm . I'm not good at this whole gpio . I know that the setting is listed in the file
Code:
/opt/CarPC/config/gpio_description
but ... What the rotor is changed gpio as I connected
Code:
# Left Control
button:10:system_mode_toggle
encoder:sl:2:sr:2:clk:13:dt:19:volume_minus:volume_plus

# Right Control
encoder:sl:2:sr:2:clk:6:dt:26:radio_seek_down+xbmcbuiltin_PlayerControl(previous):radio_seek_up+xbmcbuiltin_PlayerControl(next)
button:17:xbmcbuiltin_Fullscreen
but do not know how to change the DT. As for radio, it's black magic at all .
With this configuration, nothing works , even touch
Can I count on some help ?
I'm sorry for the google translator

Code:
# For more options and information see

# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# goes off screen, and negative if there is too much border
#overscan_left=25

#overscan_bottom=25

# uncomment to force a console size. By default it will be display's size minus
# overscan.

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
