Libreelec does not have apt-get. Apt-get is the debian package manager.

Have you followed post 5 above?

sudo gives you root (admin) privileges. In kodi you are already root user, so just ignore the 'sudo' part.

think i must give up i tried all those settings all i got was a flashing backlight

sudo apt-get ....
get...

is that what u saying

The PCB looks like an I2C adapter for hd44780 LCDs/VFDs. I did some tests with one of these (might have been a different one than yours) some 2 years ago on OE and software-wise it worked out of the box with LCDproc - just some config is needed.

Off the top of my head:

• add dtparam=i2c=on to /boot/config.txt to enable the I2C support
• install the lcdproc addon and configure it to use the HD44780 driver
• copy /etc/LCDd.conf to /storage/.config/LCDd.conf and change the hd44780 section to use I2C

I found a backup of the LCDd.conf on my HDD, the hd44780 section of it looks like this (you may need to change the port to match the I2C address of your adapter board):

Code

[hd44780]
ConnectionType=i2c
Device=/dev/i2c-1
Port=0x27
Backlight=yes
Size=20x4
DelayBus=true
DelayMult=1
Keypad=no

I remember having to do some electrical modifications to the adapter board (these may or may not apply to your board). IIRC the LCD connector pinout/I2C extender connections were different to what lcdproc expected them to be and I had to modify the board to use 3.3V for I2C (it was built for 5V).

so long,
