About

Small script written in Python for Recalbox project ( http://recalbox.com/ )
running on Raspberry Pi 2,3, which displays all necessary info on a 16x2 CLCD display
You must scrap your rom to make this script work correctly when playing.

Credits

• Original version of the recalbox script from Godhunter74
• Original project for retropie from zzeromin (https://github.com/zzeromin/RetroPie-Clcd)
• Thanks to zzeromin smyani, zerocool, GreatKStar
• Recalbox team http://www.recalbox.com

Features

• Current Date and Time
• IP address of eth0, wlan0
• CPU Temperature and Speed
• Emulation and ROM informations
• Daemon provide to manage start/stop of the script

Development Environment

• Raspberry Pi 3
• Recalbox v4.1
• 16x2 I2C HD447800 LCD (A00)

Installation

Raspberry Pi I2C GPIO Pinout

1602 LCD + IIC/IC2, 16x2 HD44780A00 or HD44780A02 (A00 = Ascii + japanese fonts, A02 = Ascii + European fonts)

Connection of the I2c to a raspberry pi 3

Scripts installation

• connect in ssh to your recalbox and mount partition to rw mode

mount -o remount, rw /

• Copy
  recalbox_clcd.py
  recalbox_clcd_off.py
  I2C_LCD_driver.py
  lcdScroll.py
  to /recalbox/scripts folder with winscp for example

• Copy
  S97LCDInfoText
  to /etc/init.d/

• then give execute right on all file

chmod +x /recalbox/scripts/recalbox_clcd_off.py
chmod +x /recalbox/scripts/recalbox_clcd_off.py
chmod +x /recalbox/scripts/I2C_LCD_driver.py
chmod +x /recalbox/scripts/lcdScroll.py
chmod +x /etc/init.d/S97LCDInfoText

Activate I2C inside recalbox

• Edit /etc/modules.conf
• Add at the end of the file

i2c-bcm2708
i2c-dev

• Edit the /boot/config.txt
  add at the end of line

bcm2708.vc_i2c_override=1

• reboot

Check I2C address

You should check your I2C address of 16x2 CLCD as this device can have different adress.
Those are two address each other normally => 0x27 or 0x3f.

Execute the following command (could take some time to complete)

i2cdetect -y 1

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- 27 -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

edit line #22 in I2C_LCD_driver.py in /recalbox/scripts with the correct adress show by the command (in this example :0x27).

nano I2C_LCD_driver.py

# LCD Address
ADDRESS = 0x27 # or 0x3f

Important note

To make this script work with Scummvm, they should be scrap but the path in the gamelist.xml should be a folder and not the scummvm "fake file".

<path>./FT/</path>
instead of 
<path>./FT/ft.scummvm</path>

great thank you,
could it be possible to do a wiki, please ?

[Choum]

could be possible, for the moment I still working to clean-up the code and do a more simple one.

@choum Libretro is written wrong here:
https://github.com/Choum28/Recalbox-Clcd/blob/master/recalbox_clcd.py#L255

[Choum]

Thank will be fix in the next commut.

[Choum]

I have add an entry to the French and English wiki.

[Choum]

Any return about this script especially on stable version of recalbox ?

Is there a way to "intercept" retroachievemet unlock ?
Same for kodi I didn't find a way to know which file is been playing, I saw that kodi already have some kind of script that do that but it require LCDPROC which seems to not be avalaible on recalbox.

[paradadf]

@choum I don't have the required hardware, so I can hardly comment on that (yet, at least).
About kodi... the people on its forum is very responsive if you don't find another way to do it online.

[voljega]

@choum I think you're only the second one here to have a lcd display for its recalbox ...

[cissou]

For kodi I think you can use the jsonrpc api :
http://kodi.wiki/view/JSON-RPC_API

[paradadf]

It would be cool if the script would identify recalbox's language (store in recalbox.conf) and show the dictionary for it. There are not so many strings to translate and you can allways fallback to english it the languague isn't supported.

[Choum]

@paradadf This is now implement. Just check the different translation if some word are incorrect, (missing turkish and chinese translation)

[paradadf]

@choum you are so efficient! Great job! I'm on my phone now, but I'll try to correct some translations tomorrow.

[Choum]

I have redo all the translation implementation, all texts are now in .lang text file to make translation easiest.

The script support all recalbox language (from 4.1).
Non European alphabet like Greek, Chinese, Russian, Arabic will use English (GB) texts (European console name)
Japanese use English text with his own specific console name.
Because the lcd HD44780 display them correctly ( but I think it could be possible for Japanese).
Future unsupported language will also use English (GB) texts in not found in .lang file.

@choum hi! I´m not sure if you´ve missed the issues and PR I made on your repo, but wanted to give you a heads up about the installation script I wrote. Currently, it is based on the changes I made on my fork. Mainly and most important moving the scripts to a separated folder to have it better organized.

Hello,

I saw them today, this is wonderfull.

@choum
Bonjour,
achat de l'afficheur sur aliexpress. (1602 16x2 HD44780 Character LCD blue + 1pcs IIC/I2C 1602 Serial Interface)
branchement ok (rétro-éclairage)
et configuration (copie des fichier & modifications) mais a la commande: i2cdetect -y 1
ça ne fonctionne pas rien de détecté.
D’où viens le pb ?
merci de votre aide.

Bonjour,
message d'euure au lancement !

sous windows avec putty:

# chmod +x clcd-install.sh

merci de votre aide.

Bonjour,

Pour le script aucune idée, je ne l'ai pas pas encore testé ni développé.

Pour la commande i2cdetect -y 1, elle devrait normalement fonctionner, une fois les modifications effectuées ET le raspberry redémarré.

Si tu fais un : LS /dev/

Tu vois un I2c-1 (ou autre I2C)

[paradadf]

@la-vague I don’t speak french, but you have to copy the clcd-install.sh script preferably to /recalbox/scripts/ with, e.g. WinSCP. Connect with putty and navigate to that folder wirh cd /recalbox/scripts/, then chmod +x ./clcd-install.sh and finally run the script with ./clcd-install.sh. Follow the instructions then...
