General firmware section for the Rock64?

[theophile]

Sure. I'm using LibreELEC with Kodi's bundled LCDproc addon. The following LCD.conf gets the LCD working with the "stock" wiring to the GPIO pins as the unit is shipped. I would expect it to work with "vanilla" LCDproc as well.

Code:

# LCDd.conf -- configuration file for the LCDproc server daemon LCDd # # This file contains the configuration for the LCDd server. # # The format is ini-file-like. It is divided into sections that start at # markers that look like [section]. Comments are all line-based comments, # and are lines that start with '#' or ';'. # # The server has a 'central' section named [server]. For the menu there is # a section called [menu]. Further each driver has a section which # defines how the driver acts. # # The drivers are activated by specifying them in a driver= line in the # server section, like: # #  Driver=curses # # This tells LCDd to use the curses driver. # The first driver that is loaded and is capable of output defines the # size of the display. The default driver to use is curses. # If the driver is specified using the -d <driver> command line option, # the Driver= options in the config file are ignored. # # The drivers read their own options from the respective sections. ## Server section with all kinds of settings for the LCDd server ## [server] # Where can we find the driver modules ? # IMPORTANT: Make sure to change this setting to reflect your #            specific setup! Otherwise LCDd won't be able to find #            the driver modules and will thus not be able to #            function properly. # NOTE: Always place a slash as last character ! DriverPath=/storage/.kodi/addons/service.lcdd/lib/lcdproc/ # Tells the server to load the given drivers. Multiple lines can be given. # The name of the driver is case sensitive and determines the section # where to look for further configuration options of the specific driver # as well as the name of the dynamic driver module to load at runtime. # The latter one can be changed by giving a File= directive in the # driver specific section. # # The following drivers are supported: #  bayrad, CFontz, CFontzPacket, curses, CwLnx, ea65, EyeboxOne, futaba, #  g15, glcd, glcdlib, glk, hd44780, icp_a106, imon, imonlcd,, IOWarrior, #  irman, joy, lb216, lcdm001, lcterm, linux_input, lirc, lis, MD8800, #  mdm166a, ms6931, mtc_s16209x, MtxOrb, mx5000, NoritakeVFD, #  Olimex_MOD_LCD1x9, picolcd, pyramid, rawserial, sdeclcd, sed1330, #  sed1520, serialPOS, serialVFD, shuttleVFD, sli, stv5730, svga, t6963, #  text, tyan, ula200, vlsys_m428, xosd, yard2LCD Driver=hd44780 # Tells the driver to bind to the given interface.
