Hello forum members,
I'm very happy with LIBREELEC, but currently, but I have one issue with it, I'm not able to solve.
My HD44780 VFD just shows junk when using LIBREELEC.
I bought a Noritake VFD GU140X32F. It can by used with serial or parallel interface and it's HD44780 compatible. I use it with an level shifter (3.3V-5V) and an converter (i2c - parallel).
It tested the the function of the VFD with an Raspberry 4B and raspbian (current version). It works fine. (small python script to display some text to the lines) So, I assume, the wiring is okay.
Using the current version of LIBREELEC (the stable one, of course) is just displaying some wired characters (blancs, rectangles and some "inverted question marks"). I tried it with the same Raspberry 4B and an ODROID C2. Both show the same output.
Of course, I installed and configured the two addons (LCDproc + XBMC-LCDproc) in LIBREEELC. The I2C-port and the device name are checked.
For my boot.ini (RP4) I added:
dtparam=i2c1=on
My LCDd.conf is:
[server]
DriverPath=/storage/.kodi/addons/http://service.lcdd/lib/lcdproc/
Driver=hd44780
Bind=127.0.0.1
Port=13666
[hd44780]
ConnectionType=i2c
Port=0x27
Device=/dev/i2c-1
Speed=0
Keypad=no
OutputPort=no
Size=20x4
CharMap=hd44780_default
DelayBus=true
KeyMatrix_4_1=Enter
KeyMatrix_4_2=Up
KeyMatrix_4_3=Down
KeyMatrix_4_4=Escape
Has anyone some suggestions to become successful?
Thanks in advance,
Joeker
