Guide : Install LCD-PI Screen On Your Current System

Hi all

Here is a quick guide to let you install the screen on your current system

Needed files :
Modules : http://aliappz8.free.fr/tmp/modules3.10 ... ite.tar.gz
You can download other modules (kernel) versions from download page : http://www.hwlevel.com/hwlevel/Downloads/downloads.html
Kernels 3.10.32 : http://aliappz8.free.fr/tmp/kernel_lcd-pi.rar

Info :
Tested on Weezy and Kali Linux

Guide :
1. From your current Pi system run the following command as root (this will extract the archive to your system) :
Code: Select all
wget http://aliappz8.free.fr/tmp/modules3.10.32_lcd-pi.lite.tar.gz
tar -zxvf modules3.10.32_lcd-pi.lite.tar.gz -C /


2. Edit the file /etc/modules (if you don't have it create one)
and add this line to it, use the line that belong to your screen model, this step does not seem to be absolutely necessary
Code: Select all
#uncomment for LCD-PI32
ssd1289

Code: Select all
#uncomment for LCD-PI43 or LCD-PI50
ssd1963

Code: Select all
#uncomment for LCD-PI33
d51


3. Extract kernel_lcd-pi.rar to your main SD (the one accessible from MS Windows) ... if you don't have enough space copy only the kernel image that belong to your screen version

4. Edit the file cmdline.txt present on your SD and put on it that line
Code: Select all
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait fbcon=map:10

4.2 "fbcon=map:10" is to use your LCD-PI as default screen

5. Edit the file config.txt present on your SD and and this 2 lines at the bottom of the file (choose the code that belong to your screen model)
Code: Select all
# uncomment to use kernel with LCD-PI43/LCD-PI50 driver compiled into kernel and SPI compression enabled
kernel=kernel_lcd-pi4+c.img

Code: Select all
# uncomment to use kernel with LCD-PI43/LCD-PI50 driver compiled into kernel and SPI compression disabled
kernel=kernel_lcd-pi4+.img

Code: Select all
# uncomment to use kernel with LCD-PI33 driver compiled into kernel and SPI compression enabled
kernel=kernel_lcd-pi33c.img

Code: Select all
# uncomment to use kernel with LCD-PI33 driver compiled into kernel and SPI compression disabled
kernel=kernel_lcd-pi33.img

Code: Select all
# uncomment to use kernel with LCD-PI32 driver compiled into kernel
kernel=kernel_lcd-pi32.img


6. Boot your Pi

7. To start the Gui as usual use "startx", it will use your current config not the LCD-PI

8. To start the Gui to your LCD-PI Screen use the following command (use the one that belong to your screen version) :
Code: Select all
startx -- -config /etc/X11/xorg.conf_LCD-PI33

Code: Select all
startx -- -config /etc/X11/xorg.conf_LCD-PI35

Code: Select all
startx -- -config /etc/X11/xorg.conf_LCD-PI43

Code: Select all
startx -- -config /etc/X11/xorg.conf_LCD-PI50


Enjoy ;)

Message to Admin : can you please put the files on your server ;) thanks

Hello. I've been trying to connect the LCD-PI35 to mynew Raspberry Pi B+, but the kernel is outdated. I can use the screen when I your old kernel, but then the USBs and the ethernet don't work. And if I use the new kernel the screen doesn't work although the other connections do. Will there be a new update to make LCD-PI work in Raspberry PI B+?

Thank you.
