Mapping Sony Bravia remote RM-ED060 CEC for Android Kodi player

I recently bought an Android box to replace my Raspberry Pi 3 player running Xbian.

One of the features I love the most on Raspberry Pi is support for CEC, since I prefer to have only one remote in use. I have controlled Kodi by using my RM-ED060 remote from my Sony Bravia KDL-50W815B that looks like this:

I did some small customization to remote configuration in Kodi on Raspberry pi by hand and I wanted to keep as much of that with my new Android box.

In order to re-map keys I used Kodi add-on called keymap editor which allows you to map almost every key you want.

This is my current gen.xml file that can be found in Android/data/org.xbmc.kodi/files/.kodi/userdata/keymaps/

<keymap>
<global>
<keyboard>
<key id="61670">activatewindow(videos,tvshowtitles)</key>
<key id="61669">activatewindow(pictures)</key>
<key id="61668">activatewindow(music)</key>
<key id="61664">activatewindow(weather)</key>
<key id="61666">info</key>
<key id="61665">contextmenu</key>
<key id="61667">activatewindow(videos,files)</key>
</keyboard>
</global>
<fullscreenvideo>
<keyboard>
<key id="61453">osd</key>
<key id="61667">subtitledelayminus</key>
<key id="61668">subtitledelayplus</key>
<key id="61669">showsubtitles</key>
<key id="61670">activatewindow(subtitlesearch)</key>
<key id="61638">aspectratio</key>
<key id="61453">osd</key>
<key id="61665">info</key>
<key id="61666">codecinfo</key>
</keyboard>
</fullscreenvideo>
</keymap>

If you would like to have the same configuration without doing the re-configuration of the keys yourself, you should copy this file to the same directory.

If you are wondering what are those key id definitions, here are all the codes that I was able to identify with keymap editor for this TV:

61448 - Return/Back
61453 - Select/OK
61488 - 0
61489 - 1
61490 - 2
61491 - 3
61492 - 4
61493 - 5
61494 - 6
61495 - 7
61496 - 8
61497 - 9
61568 - Up
61569 - Down
61628 - Stop
61636 - Rew
61637 - Fwd
61638 - Rec
61664 - Guide
61665 - Options
61666 - Info
61667 - Red
61668 - Green
61669 - Yellow
61670 - Blue
61750 - Left
61751 - Right

Compile lcdproc hd44780 driver on Raspberry Pi running Debian Stretch

In order to get my 20×4 LCD display with cheap IIC/I2C/TWI/SPI Serial Interface Board running on Raspberry Pi I had to use patched hd44780.so file downloaded from NeighborGeek. You can check it out here…

This worked fine on my RPi3 running Debian Jessie, but recently I have upgraded to Stretch and found out that his driver now is having issues. After running for longer period of time the screen would be full of garbage characters.

I thought I could repeat the steps, download source, patch the source, compile and use again hd44780.so file instead of the one provided by distribution.

First thing I did was to download latest source from GitHub:

wget https://github.com/lcdproc/lcdproc/archive/master.zip
unzip master.zip
cd lcdproc-master

Now I tried to apply the hd44780-i2c.c patch but it failed. Then I checked the hd44780-i2c.c file in the source I found out that patch is no longer needed just proper configuration in LCDd.conf.

In order to compile the latest driver from GitHub following steps are needed:

./autogen.sh
./configure --disable-libusb --disable-libusb-1-0 --enable-drivers=hd44780 --disable-libftdi
make

After you have compiled the driver, go to directory:

 cd /usr/lib/arm-linux-gnueabihf/lcdproc/

and backup existing file just in case something goes wrong:

cp hd44780.so hd44780.so.orig

Then copy the newly compiled driver in proper place:

cp /usr/local/src/lcdproc-master/server/drivers/hd44780.so .

Edit LCDd.conf and add the following after hd44780 part:

i2c_line_RS=0x01
i2c_line_RW=0x02
i2c_line_EN=0x04
i2c_line_BL=0x80
i2c_line_D4=0x10
i2c_line_D5=0x20
i2c_line_D6=0x40
i2c_line_D7=0x80
Backlight=yes
BacklightInvert=yes

You can download my newly compiled driver and LCDd.conf from this link  hd44780_debian_stretch.

I hope this has saved you some time and got your 20×4 LCD working with Debian Stretch.

Update

I have moved my LCD display to Pine64 SBC and since this is different architecture I needed to re-compile it using the same steps as above.

You can dowload aarch64 version hd44780.so aarch64.

Upgrade Xbian installation to support Raspberry Pi 3

Recently I bought two Raspberry Pi 3 devices, one for my RetroPie gaming center and one for my Kodi / Xbian always-on media-center.

Retropie with version 3.6 came out of the box with Raspberry Pi 3 support, so it was an easy to replace old unit with new one.

Xbian needs new kernel package (4.4.4+) to support Raspberry Pi 3. There are two ways to get your Xbian to support your new device: Continue reading “Upgrade Xbian installation to support Raspberry Pi 3”
