On this page, you will find all the informations needed to compile, install & use LCD4linux on Armadeus board.
Compilation & installation
Manually: Go in software/target/package/lcd4linux directory and update your local SVN repository:
svn update
Then, compile the beast:
make lcd4linux
This will install 2 files in your /local/export/: lcd4linux executable and lcd4linux.conf Launch your target, mount NFS and copy lcd4linux in /usr/bin of you target and lcd4linux.conf in /etc Change acces rights for lcd4linux.conf:
# chmod 600 /etc/lcd4linux.conf
Automatically: in buidlroot do a:
make menuconfig
and in package selection, choose LCD4Linux. Relaunch buildroot compilation and install generated rootfs on your target.
Usage
- LCD4linux needs GPIO & // port emulation drivers to be loaded first. So, please refer to GPIO Driver page (you need to have gpio.ko & ppdev.ko modules loaded).
Be sure to have a /dev/parport/0 node. (automatically created when your run loadgpio.sh script)
- a configuration file (/etc/lcd4linux) is also needed to configure layout and widget, so if you want to change these parameters, this is the place to look at
- LCD4linux is then easily launched:
# /usr/bin/lcd4linux
It automatically daemonizes itself.
