PiFace Control and Display 2

Hi you all,

I have bought a Piface Display and Control 2 for my Raspberry Pi 4. On Raspbian it is working like a charm, but I can't figure out to let it work with LibreElec and the LCDProc add-on.
I have copied all the useful config.txt settings from Raspbian to LibreElec with no luck. The driver that I use in LCDProc is: lirc
Can someone help me solve this?

Thanks a lot!

Quote from Da Flex

You have to enable LIRC by creating the config file /storage/.config/lircd.conf. Read here for details.

Da Flex Thanks! I will give it a try.

Da Flex I did what the tutorial told me to. The IR reseiver is working, but the LCD display isn’t. I’ve installed the XBMC LCDproc add-on without any luck. I saw a video on YouTube

Da Flex Yes, the file is present.
I am a step further and the display is flickering now. JeeeeeJ !!! But now I get the following error message:

HD44780: PiFaceCAD: mcp23s17_write_reg: There was a error during the SPI transaction: Invalid argument

any ideas?

Da Flex where could I find these library file in LibreElec?

Nope, no go.

Yesterday I had installed Raspbian on my Pi and installed pifacecad on it and that was working. But when I used LCDproc it also worked, but the display was all scrambled and the LCDd command with the config loaded did not stop.

This morning I read a post on raspberrypi.org that OpenLX has suddenly stopped on December 2015 in devolping there Python software pifacecad.

Why do they still ship those hats then, if they don't developing there software anymore ? I asked the store where I bought the PiFace CAD from for a refund. I hope I could exchange it for something else from Adafruit they are still devolping

That's the pity of Linux, because the most software is freeware the designers and developers are dependent of crowdfunds and the good will from others. If that stops or the costs are higher than the profits some good projects quit.

Anyway, I bought myself an single LCD display from Adafruit with HD44780 driver support. I still have to solder it, apply the LCDproc software, and we're good to go. Then I can also use the Pi without a TV monitor for listing to my music

Thanks again for your support!
