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>

Bonjour,

Ci-dessous un petit script PowerShell que j'ai crée pour trouver toutes les roms en doublon que j'avais sur ma recalbox (le script se base sur les nom renseigné dans le fichier gamelist.xml, donc il faut que les roms soit scrap).
SI un doublon est trouvé il est affiché à l'écran puis stocker dans un fichier texte

Pour le lancer via PowerShell :
PowerShell.exe -ExecutionPolicy Bypass -File .\doublon.ps1

Il dispose de trois arguments, la source (dossier roms de la recalbox), la destination (l'endroit ou est stocké le fichier de résultat), et système (si vous voulez scanner uniquement un dossier de rom précis, par défaut il scanne tout).

Pour plus d'infos sur le script
dans powershell
Get-help doublon.ps1 -full
