Hello,
i have a SSD1306 Adafruit OLED 128x64 4pin GPIO
But I didn't´get it to work.
Can anyone help please?
It is so complicated
LibreELEC:~ # LCDd -c /storage/.config/LCDd.conf
Could not open driver module /usr/lib/lcdproc/hd44780.so: /usr/lib/lcdproc/hd44780.so: cannot open shared object file: No such file or directory
Driver [hd44780] binding failed
Could not load driver hd44780
There is no output driver
Critical error while initializing, abort.
LibreELEC:~ # i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

And here is my LCDd.conf

# Select what type of connection. See documentation for availabe types.
ConnectionType=i2c
# I/O address of the LPT port. Usual values are: 0x278, 0x378 and 0x3BC.
# For I2C connections this sets the slave address (usually 0x20).
Port=0x3C
# Device of the serial, I2C, or SPI 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, lcd2usb, and usb4all)
# [default: 800; legal: 0 - 1000]
#Contrast=0
# Set brightness of the backlight (lcd2usb and usb4all):
# Brightness is the brightness while the backlight is set to 'on'.
# [default: 800; legal: 0 - 1000]
#Brightness=1000
# OffBrightness is the brightness while the backlight is set to 'off'.
# [default: 300; legal: 0 - 1000]

# 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=128x64
# 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 controller with 'extended mode',
# set this flag to get into 4-line mode. On displays with just two lines, do
# not set this flag.
# As an additional restriction, controllers with and without extended mode
# AND 4 lines cannot be mixed for those connection types that support more
# than one display!
#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]

# 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 <KeepAliveDisplay> 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 <RefreshDiplay> 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
