installing 16x2 i2c lcd on volumio2

Hello,

I am trying to install a 16x2 lcd via i2c on raspberry pi2 that running volumio-0.979-2016-08-20-pi
I followed andypi’s andypi.co.uk/?p=334 tutorial but cant make it running.

sudo i2cdetect -y 1

sudo mpdlcd --no-syslog
INFO mpdlcd.lcdrunner LCD screen is 16x2
INFO mpdlcd.lcdrunner MPD screen added to lcdproc.
INFO mpdlcd.mpdwrapper Connecting to MPD server at localhost:6600
INFO mpd Calling MPD connect(‘localhost’, 6600, timeout=None)
INFO mpdlcd.lcdrunner Starting update loop.

I got no error but cant make it show mpd info at lcd.

Please help me.
Regards.

Because of i am using i2c lcd i changed andypis LCDd.conf file a little bit like down below.
but still having this problem: sendvid.com/oyhasm6a

Hitachi HD44780 driver

[hd44780]

Select what type of connection. See documentation for types.

ConnectionType=i2c

Port where the LPT is. Usual value are: 0x278, 0x378 and 0x3BC

Port=0x27

Device of the serial interface [default: /dev/lcd]

Device=/dev/i2c-1

Bitrate of the serial port (0 for interface default)

Speed=0

If you have a keypad connected.

You may also need to configure the keypad layout further on in this file.

Keypad=no

Set the initial contrast (bwctusb and lcd2usb) [default: 500; legal: 0 - 1000]

Contrast=100

Set brightness of the backlight (lcd2usb only) [default: 0; legal: 0 - 1000]

Brightness=500
#OffBrightness=0

If you have a switchable backlight.

Backlight=yes

If you have the additional output port (“bargraph”) and you want to

be able to control it with the lcdproc OUTPUT command

OutputPort=no

Specifies if the last line is pixel addressable (yes) or it controls an

underline effect (no). [default: yes; legal: yes, no]

#Lastline=yes

Specifies the size of the LCD.

In case of multiple combined displays, this should be the total size.

Size=16x2

D7=14
D6=23
D5=24
D4=25
RS=7
EN=8
BL=18

For multiple combined displays: how many lines does each display have.

Vspan=2,2 means both displays have 2 lines.

#vspan=2,2

If you have an HD66712, a KS0073 or another ‘almost HD44780-compatible’,

set this flag to get into extended mode (4-line linear).

#ExtendedMode=yes

In extended mode, on some controllers like the ST7036 (in 3 line mode)

the next line in DDRAM won’t start 0x20 higher. [default: 0x20]

#LineAddress=0x10

Character map to to map ISO-8859-1 to the LCD’s character set

[default: hd44780_default; legal: hd44780_default, hd44780_euro, ea_ks0073,

sed1278f_0b, hd44780_koi8_r, hd44780_cp1251, hd44780_8859_5, upd16314 ]

(hd44780_koi8_r, hd44780_cp1251, hd44780_8859_5 and upd16314 are possible if

compiled with additional charmaps)

#CharMap=hd44780_8859_5

If your display is slow and cannot keep up with the flow of data from

LCDd, garbage can appear on the LCDd. Set this delay factor to 2 or 4

to increase the delays. Default: 1.

#DelayMult=2

Some displays (e.g. vdr-wakeup) need a message from the driver to that it

is still alive. When set to a value bigger then null the character in the

upper left corner is updated every seconds. Default: 0.

#KeepAliveDisplay=0

If you experience occasional garbage on your display you can use this

option as workaround. If set to a value bigger than null it forces a

full screen refresh seconds. Default: 0.

#RefreshDisplay=5

You can reduce the inserted delays by setting this to false.

On fast PCs it is possible your LCD does not respond correctly.

Default: true.

DelayBus=true

If you have a keypad you can assign keystrings to the keys.

See documentation for used terms and how to wire it.

For example to give directly connected key 4 the string “Enter”, use:

KeyDirect_4=Enter

For matrix keys use the X and Y coordinates of the key:

KeyMatrix_1_3=Enter

KeyMatrix_4_1=Enter
KeyMatrix_4_2=Up
KeyMatrix_4_3=Down
KeyMatrix_4_4=Escape

but when i run mpdlcd and play a song my backligt of lcd flickers, it turns on and off continiously. and no info displayed on lcd.
