Rasperri Pi + Runeaudio + LCD I2C 2004 20x4

[dom_france]

Hello,

First, I would like to thank you for this update version (this image) :
RuneAudio_rpi2_rp3_0.4-beta_20170229_2GB.img.gz

I tried it this week end, because, I would like to automatically play a playlist with MPC and a service when my Raspberri switch on, and with this image, OK for me.

After, I transfer a python script (name shutdown.pi) to switch off my rasperry pi 3, OK, very good too, my solution is OK.

Now, I would like to add a display, with I2C protocole, like LCD I2C 2004 20x4, and I need your help, because I can not start the order "i2cdetect -y 1" to scrut my electronic editing.

Thank you per Advance

Hello everybody,

today, I try to install "gcc" (because Adafruit library need gcc) but without success : no space enough on my system :



it's strange because my SD card is a 16GB... only 2GB for system...

Can someone help me step by step for the establishment of my display?

Thank you...

DOM



I use this version : RuneAudio_rpi2_rp3_0.4-beta_20170229_2GB.img.gz
because I wanted these 5 points:

1) autoplay at startup (on usbkey with lots of music folder
2) GPIO management OK
3) button shutdown (electric)
4) random reading at startup
5) I2C display

my last point (5) is difficult for me, please help me...

Bye

Hi,

in this forum how-to-enable-i2c-t1287.html, I see this :


3) Open /etc/modules-load.d/raspberrypi.conf with:

nano /etc/modules-load.d/raspberrypi.conf

And add this at the end:

i2c-bcm2708
i2c-dev

But I don't have a file name "raspberrypi.conf in /etc/modules-load.d...

?

My Raspberry is a raspberry pi 3 Model B.

A+++

Tonight I try this with success, but I'm no sure :

I make a new file in /etc/modules-load.d with this name : i2c.conf

I edited this file with "nano /etc/modules-load.d/i2c.conf" and I put this (and only this) : i2c-dev

I save and quit this file.

Then, i type this : modprobe i2c-dev

and finally, i2cdetect -y 1 ok :



but I'm no sure...

is it normal that I have the past by creating a file in /etc/modules-load.d ?

[dom_france]

WIth this order "lsmod | grep i2c", I get this :



... Normal ?

OK or NOT OK ?
